Introduction.
Since the publication of the Enumeratio Plantarum For- mosanarum” and Flora Montana Formose,” a large number of collections has been sent to me for determination, by the Go- vernment of Formosa. The collections are in greater part from the mountainous regions of the island and contain a considerable number of novelties. As the flora of Formosa has a close affinity to the floras of Japan and China, it is very important, in order to work up the materials, to make an exhaustive com- parison of the collections with specimens from the two countries.

At the same time, as the flora of the island contains a con- siderable number of elements from India, including the Himalayas and the Malay peninsula and archipelago, it is equally desirable for my work that the same should be done with the specimens of the regions above mentioned. For a comparison with Japanese specimens, the Herbarium at Tokyo will answer fairly well, as it includes nearly all Japanese plants, though not exhaustively. Chinese plants, however, are here only very poorly represented. I, therefore, found it very unsatisfactory to work up so big a collection only in the Herbarium at Tokyo. Moreover, as a con- siderable number of Chinese plants are represented in the Her- barium at Kew, and also in that at Dahlem, and the type speci- mens of FRANCHET are especially preserved in the Herbarium at Paris, and those of Maximowicz, in that at St. Petersburg. I thought it very necessary for my work to see all the plants represented in the principal herbaria of the West. It was my great good fortune that I was given an opportunity of visiting these different herbaria in order to make an exhaustive com- parison of my materials with the collections preserved in them. With this intention I first went to Kew taking all my materials with me. There I pursued my work with specimens of the floras to which our flora is more or less related. The comparison made, in most cases, was confined to the flora of Asiatic regions, especially, to China, Korea, India, the Himalayas, and the Malay peninsula and archipelago ; but, sometimes, it was extended, when necessary, to Australia, the Arctic and Antarctic regions, Europe, Africa, America and even to Polynesia. I found that many of the species of my collections are represented in the Chinese herbarium at Kew, and alsc among the specimens from other
regions. At the same time, I found also that the greater part
MATERIALS FOR A FLORA OF FORMOSA. 3
of my materials is not yet represented at Kew, and that, in great probability, they are species not yet described. After finishing my work at Kew,” I went to the Herbarium at Paris, in order to see the type specimens of Chinese plants mainly described by FRANcHET. Then, my work was pursued in the Herbarium at Dahlem where are preserved a good many collections of Asiatic flora. My purpose in going to Dahlem was to see especially the specimens mentioned in Prof. Deus’ “Die Flora von Central China.’” In Dahlem, as in Paris, I devoted myself to making notes of the specimens preserved there, as I had not brought my materials with me. I especially devoted myself to making sketches, on tracing paper, of the specimens which are represented only in Dahlem and nowhere else, so that I could make a close comparison with these sketches on my return to Tokyo. After finishing my work, I went, with the same purpose, to the Her-
barium at St. Petersburg

in order to see the type specimens of Maxrmowicz. During my work on the continent, I was successful in placing some species which I had not been able to determine at Kew. Still, many of the plants in my collections which remain as yet undetermined, are not represented in any of the herbaria on the continent. It is, therefore, highly probable that they are species not yet described.
The plants mentioned in the present work are mostly of species newly described and, if not, they are new to the flora of
Formosa, though there are a very few which were previously

2) During my stay at Kew, I was away from my work, for a little more than a week, when I went to Brussels to take part in the International Botanical Congress, then being held there, at which I presented a paper entitled * Botanical Survey of the Government of Formosa, with short Sketches on the Vegetation and Flora of the Island.” The paper is now in press at Brussels.

recorded from that island. The references here made under each species are extremely limited, as there is no space for full ac- counts. Critical views regarding species already described by my- self or by others, are here given. In the present work, it is my desire to mention all the species recorded from Formosa, which have appeared in different publications, since the issue of the Enumeratio Plantarum Formosanarum and Flora Montana For- mosæ. So that, practically speaking, the present work is an exhaustive supplement bringing our former publications up to date.
To mention the number of species of the flora* of the island, known to us up to the present time, there are, in the Enumeratio, 1999 species belonging to 701 genera and 153 families. In my Flora Montana, 392 species are mentioned belonging to 266 genera and 70 families; in the present work, I have mentioned 735 species belonging to 343 genera and 109 families, thus adding to our present knowledge of Formosan flora, 567 species, 72 genera and 2 families. Excluding all those species which appear for a second or third time, in the above three papers, the total number of the plants of the island is 2660 species belonging to 836 genera and 156 families. The following lst shows genera added to those mentioned in our former publications.
Most of them are new to the flora of the island.

In the present work, a few species are mentioned under families different from those to which they are referred in the former publications. As the alteration of families is a matter of importance, I shall here try to comment briefly on this point. There are three species which are properly transferred from one family to another. One is a plant which was called Rehmannia Oldhami Heusr, formerly ıeferred to Serophularinex, but now to Gesneraceæ. The reference to the species is given under the heading of the genus. The plant was first referred to ÆReh- mannia? by W. B. Hemstry who afterwards thought it better to regard it as representing a distinct genus from Ichmannia. He then established a new genus, Matsumuria,’ for the plant, and referred it to Gesneracex on account of its perfectly one-called

ovary with two parietal placente. Almost at the same time, this plant attracted the attention of SOLEREDER who saw the very same specimen at Kew, and established a new genus called Titanotrichum” which was published in September, 1909, when the description of HrMsLEY was in press. The priority has at last been given to the genus of SOLEREDER. In the present work, the plant is mentioned as Titanotrichum Oldhami SOLERED. and is referred to Gesneracex. Another plant is Logania dentata” formerly described by myself, which should be transferred from Loganiacex to Scrophularineæ. In 1906, when I published the plant in my Flora Montana Formosæ, I was informed by Mr. E. D. Merritt that he thought that the Philippine plant Nertera dentata Ermer” (with which my plant is identical) should be refer- red to Hemiphragma heterophylla Wat. of the Himalayas. I also alluded to this matter in the foot notes to my paper in which I expressed the opinion that it was still questionable whether my plant should be referred to Hemiphragma or not. At Kew, I compared it with the type of the latter species and found that they were very similar excepting slight differences in the number of the corolla-lobes and in the attachment of the stamens to the corolla-tube. So far as I can ascertain from the description of Hemiphragma given in BrentHam and Hooker, f. ‘‘ Genera Plan- tarum IT. p. 959,” the genus has a five-lobed corolla and four stamens, affixed to the base of the tube. But, in my plant, the corolla is four-lobed and the stamens are also four, but, affixed to the middle of the tube. It may be questioned, however, if the
flowers of my plant may not be imperfect ones, as it was

collected when the flowering season was nearly over. I examined a considerable number of the specimens, but I could not find more than one or two flowers upon which the description and figures in my papar could be based. It may be well conjectured that my plant in the normal state of its flowers may have a five- lobed corolla with four stamens. I therefore think it better to transfer my plant from Loganiaceæ to Scrophularinex, referring it to Hemiphragma heterophylla Wau. Another plant which I may here mention, is Zllisiophyllum pinnatum Maxtno, which was referred to Hydrophyllaceæ, but, in the present work, is transferred to Serophularineæ. In 1871, Maximowicz established the same genus upon a Japanese plant in ‘ Mél. Biol. Vol. XIII. p. 18”, then named by him as E. reptans. It is very probably to be referred to Polemoniacex, because of its seeds which produce a considerable amount of mucilage in the moist condition,— a character which is all but peculiar to the same family. The plant has also a close relation with Hydrophyllaceæ, so far as the leaves and flowers are concerned. It seemed, therefore, rather questionable to Maxrmowicz himself, to what family the present genus should be referred. In 1876, the same genus was referred to Hydrophyllaceæ by Benruam and Hookek. f. in their ‘ Genera Plantarum” IL. p. 829. A little later, in 1890, it was referred to Scrophularineæ by Baron in “ Bull. Soc. Linn. Paris, No. 105.” Here, he expressed his opinion that the doubtful genus belongs neither to Polemoniaceæ nor to Hydrophyllaceæ, but to Scrophularineæ. Moreover, he stated that its nearest of kin is Litorella of the same family. In 1892, it was again re- ferred to Hydrophyllaceæ by Perer in “ Ener. u. Prantu. Nat. Pfl.- fam. IV. 3-a, p. 63.” As to the nomenclature of the plant, there had been no difficulty, until Mr. T. Marino (1906) called his attention
8 ART. I. —B. HAYATA:
to the similarity of the figures of Moseleya pinnata HeumsL. in Hooxker’s Ic. Pl. XXVI. t, 2592, (1892), and his drawings of Ellisiophyllum reptans Maxim. which he had just made. The same plant is an extremely troublesome one, as to its genus and species as well as its family. Previous to the establishment of Ellisiophyllum by Maxtmowicz, the same plant was fouud in Nepal and is described as Mazus pinnatus WALL. The plant was after- wards referred to Ourisia (1835), then to Hornemannia (1846), then to Sibthorpia (1876) and finally to Moseleya (1893). The last genus was established by W. B. Hemstey, as there was, as he thought, being quite unaware of Ellisiophyllum of Maxrmowrcz, no proper genus for the plant. As is clearly seen in the com- parison of the drawings of Moseleya and Hllisiophylium, above mentioned, they are two different genera established for one and the same plant. Accordingly, it is clear that the former should be reduced to a synonym of the latter. The present plant should, therefore, be referred to Ællisiophyllum with the specific name of pinnatum, as is stated by Mr. 1% Makino.” Now I may return to the question as to what family the plant should properly be referred? In my paper “ Flora Montana Formosæ,” I mentioned the plant under Hydrophylla- ceæ. In 1909, Herr Professor A. Brand wrote me that he had some doubt about this plants belonging to Hydrophyllaceæ and expressed his desire to study it, asking me to send him the materials. This being done, he soon published his paper on Ellisiophyllum” in which he expressed the opinion that BaAıLLox’s statement, to which I have referred above, was correct. Accord- ing to his opinion, all the Hydrophyllaceous plants have, without

exception, two parietal placentæ, which connate themselves in the innerside of the capsules. But, it is quite otherwise with the present plant, which bears only a placenta rising by itself to mid- way from the base of the ovary, i.e. a central placenta, as is the case with Scrophulariaceous plant. The genus is, therefore, not to be referred to Hydrophyllaceæ, but should be referred to Scrophularinex. There is a little difference between his state- ment and Mr. Maxıno’s drawings, regarding the placenta. So far as I can judge from the latter figures, the ovary is perfectly two- celled, with axial placenta. But, in the figures given in HookEr’s Icones Plantarum, the ovary is nearly, but not perfectly, two- celled, as the placentæ are free at the apex. Although these differences exist, they are, in my opinion, to be regarded as results of individual mutability, to which all plants are more or less subject. Taking all these things into consideration I think the plant should be referred to Scrophularineæ, as was stated formerly by BAILLON and quite recently by Prof. Braun. Finally, I may mention one more plant which is also extremely difficult as to its reference. It is Zriplostegia glandulifera Watt. The genus was first established by WaArrich on a Himalayan plant in his manuscript and also in DC. Mem. VII. t. 4, referring it to Valerianeæ, as we see in “DC. Prodr. IV. p. 642.” The genus 4s, however, transferred to Dipsaceæ by BENTHAM and Hooker, f. in their Genera Plantarum II. p. 158, with the remark ‘Genus hucusque ad Valerianeas quibus inflorescentia accedit adscriptum, sed involucellum, semen albuminosum, folia et indumentum omnino Dipsacearum et odore Valerianearum caret,” and also on p. 1230, with another remark, “ Stamina per- fecta sæpe 3 tantum ut in Valeriana affinibusque, et genus omnino medium tenere videtur inter Valerianeas et Dipsaceas,
10 ART eB. HANATA:
etsi characteres essentiales posteriorum.” The genus is also referred to Dipsaceæ by Hemsney in Forses and HEMsLEy’s Index Flora Sinensis, I. p. 399, and also by F. Hack in Ene. u. Prant. Pfl.-fam. IV.-4 p. 187. When I examined the plant in the Herbarium at Tokyo, where we have very few Chinese specimens for comparison, I thought that it must be a plant belonging to Valerianeæ, and I saw that the plant was quite referable to the genus Hæckia, then newly established by Professors ENGLER and GRABNER in DIELS’, “ Die Flora von Central
551)
China. I saw also that the description of 77. Aschersoniana ENG. and GRÆBN. accorded fairly well with my plant, though there are some minute points in which they do not exactly agree. As the plants of this family are usually subject to some muta- bility in the magnitude of flowers and leaves, I thought the present plant to be identical with H. Aschersoniana. During my work in the Herbarium at Dahlem, I examined the type of the Heckia and also the specimens of the Triplostegia of the Hima- layas, and found that they are exactly the same as those with which my plant also is identical. The present plant is, therefore, mentioned, in this work, under the name of Triplostegia glanduli- fera Watt. As to the position of the present genus, it is, in my opinion, much more desirable to refer it to Valerianeæ, than to place it in Dipsaceæ.
I may here mention another remarkable case given in this work. Of all the plants contained in the flora, perhaps the most striking genus is Oreomyrrhis, which is all but peculiar to the Australian flora, belonging to Umbelliferæ. The genus is, not only new to the flora of the island, but also new to that of the

northern hemisphere. Another case of novelty is the addition of two families to the present flora. They are Hernandiaceæ and Myristiceæ.
The materials upon which this work is based are, in greater part, the collections made by the Governmental Botanical Survey, supervised by Mr. T. Kawakami, during 1906-1909. I have also referred to a small set of specimens of Loo-chooan plants, collected by Mr. G. Naxanara, a few dubious specimens from the Loo- choo and Bonin islands, preserved in the Herbarium at Tokyo, and small collections of Formosan plants sent by Mr. 8. Nacasawa and the late N. Kontsxt.
The present work was, in great part, carried out by myself in the Herbarium at Kew. <A few families were examined by the staff of the same laboratory. Of the staff, 1 may mention Dr. O. Starr for doubtful families, Mr. E. N. Brown for Ascle- piadeæ and Aroideæ, Mr. R. A. Rorre for Umbelliferæ and some Orchids.
In conclusion, I must tender my hearty thanks to Prof. J. Marsumura for his encouragement during the present work. I also wish to express my sincere gratitude to Mr. K. Osxrma, Ex-Chief of Civil Government of Formosa, by whose graciousness extended towards myself, I was able to visit the principal herbaria of the West. To Lieut. Col. D. Pram, Director of the Royal Botanic Gardens, Kew; to Monsieur le Prof. Dr. H. Lecomte, Directeur de la Galerie de Botanique du Muséum à Paris; to Herrn Prof. Dr. A. Exczer, Direktor des Kgl.

The present plant is very like, or perhaps the same plant as, HEnry’s specimen No. 1320 labelled C. parviloba. The type of C. parviloba is quite different from our plant and also from Hernry’s specimen, in having hirsute sepals, much thinner and
less glabrous leaves.

Distris. China and Indo-China.
Ogserv. Covered by yellowish soft hairs; leaves trifoliolate, petioles 5 em. long, leaflets ovate acute 8 cm. long, 34 cm. broad, obscurely dentate or nearly entire, lateral leaflets oblique at the base; panicles few-flowered, peduncles 4-5 cm. long; sepals 4, ovate, nearly acute, with yellowish soft hairs on the outside, glabrous inside; stamens many, 12 mm. long, filaments hairy on the margin and outside, quite glabrous on the inside, anthers narrow, glabrous ; achenes hairy, fusiform with two distinct ridges, tails with long hairs.
In my Flora Montana Formosæ, I doubtingly referred this plant to C. Wightiana. After examining more carefully, I have found that the specimen is the same as the Philippine form of C. Leschenaultiana DC. The present plant differs from C. Wightiana in having fusiformed achenes and thread-like filaments. C. Leschenaultiana described in Kuntzze’s “ Monog. Clemat. p. 167,” has lanceolate leaves, while the Formosan plant has ovate

The present plant differs from C. recta and also from C. paniculata in having longer tailed fruit and much more rounded leaves. The leaves have generally three leaflets, or sometimes five-leaflets, then the distance from the first pair to the second
pair is nearly as long as the petioles.

The present variety differs from the type in having much smaller flowers, oyate-lanceolate leaves, and not leafy inflo- rescence. It resembles the type in stamensand achenes, and especially in glabrous sepals turning black when dried. The type has usually larger flowers, with sepals twice as longer as that of the variety, and longer, looser, and less flowered in- florescence, with longer peduncles. The present variety is represented at Kew by a specimen from Hongkong, which is labelled C. uncinata, but is different from the type of the species
mentioned.

I. p. 136, and also very like the European A. arenosa Scor. Although I did not, at that time, see ANDERSON’S specimen, I thought that the plant might be identical with A. tarazxacifoiia. While studying here at Kew, I have compared it with the type of the some species and have found that they are quite different. The Formosan plant is distinguishable from the Indian in having nearly erect and stouter pods, larger seeds, and smaller leaves and also in bearing very long stolons. The Indian plant appears to be of more tender habit, with curved pods, narrower, smaller seeds, and larger, thinner leaves. Moreover, the present plant differs from A. arenosa Scor. in having longer pods, smaller flowers, and leaves with more rounded lobes. The description given above is drawn up from a specimen numbered 680, which is of a rather
elongate form and prostrate habit.

There is a specimen very much like this in the Kew Herba- rium. It is labelled C. hirsuta Lan. but quite different from the type. As the present plant is quite easily distinguishable from the type of ©. hirsuta Linn., it is advisable, in my opinion, to regard it as representing a variety of the type, rather than to
regard it as a form of it.
Cardamine hirsuta Linn. var. rotundiloba Hayarın. v. Herba glabra, caulibus simplicibus 15 cm. longis pauci-foliatis.

In my paper above cited, I mention that the plant is somewhat near C. asarifolia Lixx. from which it is distinguishable by the reniformed or cordate leaves. While studying here at Kew, I have
found that the plant is also near C. viole/olia O. S. Scaurz. from

which it is separable in having rather angulate leaves and very much smaller flowers. Flowers of my plant are 3 mm. long, while those of the Chinese C. violæfolia are 8 mm. long, or even
more. Those of C. asarifolia Linn. are also much larger.

Fl. Lutch. p. 371. As the Formosan plant is exactly identical with Dr. Iro’s plant, I used the same name for my plant. While working here at Kew, I have compared with Mr. SPRAGUE the present plant with the type of the named species, and have found that they are clearly not identical. The former is easily distinguishable from the latter by many points but especially by the very much fewer and much more slender prickles on the fruit. In WarricH's species, the prickles are much more numerous and stronger. Our plant is very near #. subsessilis SPRAGUE (=, echinatus Lour.), but differs from it in having much fewer and more slender prickles. The new species is named in honour of Mr. T. A. Sprague who has cordially assisted me in
many ways during my work at Kew.

The present plant is near C. articulatus ; but differs from it in having more rounded leaves and transversely wrinkled carpels in a dried specimen. The leaves are nearly rounded, or slightly cordate at the base, shortly acute or nearly rounded at the apex, remotely serrulate on the margin, while those of C. articulatus are nearly obovate, acute or rounded, but never cordate, at the base. The carpels of the latter plant are not wrinkled, but rather smooth
even when dried.

The present plant is described in my ‚paper above cited as representing a variety of Rhamnus arguta Maxim. At Kew, I have examined the co-type of the latter plant and found that the diffe- rence between the type and the variety is so great that I have thought it better to raise the latter to specific rank. The new species differs from the other in having slender flowers with longer
styles, and still more in the supra-axillary inflorescence.

The present plant was erroneously regarded by myself and other botanists as identical with A. oblongum War. At Kew, I have compared the plant with the type of the named species and found that they do not entirely agree. I have examined several
forms of Acer oblongum from the Himalayas, China and Formosa,
63 ART. I.—B. HAYATA :
but I have not found that any of the forms of the same species comes in accord with the Loo-chooan plant in respect of the shape of leaves. Accordingly I have thought it better to regard the latter as representing a new variety of the species. The present variety differs from the type in having ovate leaves, quite rounded at the base, acuminate at the apex, with three distinct nerves, and two distinet lateral veins on both sides of the central nerve. The leaves of the type are oblong, or obovately oblong, or rarely ovate-oblong, much more obtuse at the apex, and nearly acute at the base, pinninerved or obscurely three-nerved, with more than six lateral veins on both sides of the central nerve. The new variety is named in honour of Dr. T. Ito who has done so much for the study of the flora of these interesting
Archipelago.

The present plant is described by myself in Tokyo Bot. Mag. XX. p. 54, and afterwards is reduced to a synonym of C. sinensis, in Fl. Mont. Formos. p. 92. Having examined the type of C. sinensis Hemsu. at Kew, I have, however, found that my plant does not quite agree with Hemsrey's species. C. formosana differs from C. sinensis mainly in having narrower leaves with shallower denta- tion, and much larger petaloid sepals. The Formosan plant should, therefore, be regarded as a species distinct from the conti- nental plant.

The present plant is very near D. scabra Tauxs. and D. pulchra VipaL ; but it differs from the former in having dentate stamens and in the number of styles which are usually five; and from the latter, in having quite obtuse leaves. In Vıpar's plant, the leaves are usually more acuminate, and very acute at the apex. Deutzia crenata S. et Z. 0. Taiwanensis Maxtm. cited above may possibly be identical with this plant, thoush I have found some different points between the description of Maxmowicz and that of the present one; for the Deutzia credited in Formosa by Maxrmowrez, so far as is considered from the locality given by him, may not be otherwise than this plant as it is the only one to be found in the lowland of Formosa. Maxrmowicz’s plant is not near D. crenata S. et Z., nor is it referable to a variety of that species; but it must
be a quite different one, so far as the diagnosis is concerned.

As far as I can judge from the description of the variety à. Taiwanensis, it is so very different from D. crenata S. et Z., that it is quite proper to raise it up to specific rank. The fruit of the present plant is very similar to those of Hrnry’s specimen
at Kew.

Very like, or perhaps quite identical with, a Chinese specimen at Kew which is named Trichosanthes palmata Roxs. The type of the same species is quite diferent from the Chinese specimen and also from the present plant. The bracts of the type are usually entire or but a little fimbriate in the
upper ones, while those of my plant are very deeply fimbriate.

Alsomitra integrifoliola Hayata n. n.
Alsomitra clavigera Henry List of Pl. Formos. p. 46; Marsum. et Haıyara Enum. Pl. Formos. p. 164, (non Hook. f.)
Gynostemma integrifoliola CoGnIaux in DC. Monogr. Phanerog. Tip. 316.
The present plant is mentioned in Henry’s List of Plants from Formosa p. 46, as Alsomitra clavigera Hook. f. and is also referred to the same species by myself in Enum. Pl. Formos. p. 164, as the description of Hooker’s plant is, in greater part, in accord with my plant. Mr. E. D. Merritt of the Bureau of Science, P. I., when we were together looking over the Formosan collections in the Herbarium at Tökyö, told me that he thought the plant to be identical with Gynostemma integrifoliola Coan. To what species the present plant should be definitely referred was a very difficult question for me, until I saw the types of Hooxer’s and Cocnıaux’s species and Henry’s specimen, all preserved here in the Kew
Herbarium. A comparison of my plant with the specimens above
122 ; OME, TR, TEU NEN 2
mentioned shows me clearly that it is exactly the same as the specimen in Henry's collection, (which lacks flowers), but quite different from Hooxker’s plant. I have also found that my flowering specimen accords very well with Gynostemma integrifoliola Cocn., the specimen of which lacks fruit. In the original de- scription of Coaniavx, there is mentioned “ fructus fuscus glaber vel leviter puberulus, 7-8 mill., crassus.” The description must, I infer, have drawn up from a premature fruit, as there is given no account about seeds. The fruit of this species are, as is seen in my specimen, as long as 4cm. and has numerous winged seeds. The Gynostemma of Coaniaux, as far as my collections with flowers and fruit are concerned, does not accord with the general characters of Gynostemma, but quite agrees with those of Alsomitra. My plant and also Coantavux’s plant, therefore, should be referred to the latter genus. Accordingly, the new combination, A. integrifoliola Hayara is much to be desired for the present plant. It comes very near to A. clavigera Hoox. f., but differs from it in having much smaller pod which is only half the size of those of the latter plant, and also in having much smaller seeds with thin wings, which are bluntly and ob- scurely indented on the margin. The seeds of Hooxker’s plant are
much larger and have acutely, clearly and grossly indented wings.

The present Begonia is the most common one in Formosa. It differs from B. laciniata Roxg. var, Bowringiana in having quite glabrous leaves. The latter variety is always tomentose or pubescent. The Formosan one should, therefore, be another variety of B. laciniata to which Mr. W. B. Hemsrey also refers in Ind. Fl. Sin. I. p. 322. It bears some resemblance to 2. sinensis ; but differs from it in having larger flowers and glabrous
leaves.
