XXV., ARTICLE 19. LIBRARY NEW YORK SOTANICAL CARDEN Flora Montana Formosz An Enumeration of the Plants found on Mt. Morrison, the Central Chain, and Other Mountainous Regions of Formosa at Altitudes of 83,000—138,000 ft. By B. Hayata, Rigakuhakushi. Yy* Assistant in the Botanical Institute, College of Science, Imperial University, Tokyo. With 41 plates and 16 woodcuts. Introduction. In the year 1905, Professor Marsumura and I jointly published an enumeration” of plants found in Formosa, comprising about two thousand species of flowering plants, ferns and their allies. At that time, our collections, with the exception of a few sets of plants found on Mt. Morrison, did not extend to elevations of any great altitude. It is, therefore, quite proper to regard it as an enumeration of the flora of the low districts. On the botany of the montane zone, there exists no special 1) Mazsumura, J., and Hayara, B.—Enumeratio Plantarum Formosanarum, in Journ. Sci. Coll., Imp. Univ.

In the present work, it is my desire to give some complete information relating to the montane zone of the island. The majority of the collections upon which this work is based, were made by the officers of the Government of Formosa. Some materials were collected by Prof. 8. Honpa in 1896, and by Mr. R. Torm in 1900, both from Mt. Morrison. In November 1905, a botanical excursion was carried out for the first time on the above mountain by Messrs. T. Kawaxamt, 8. Nacasawa and G. NAKAHARA, and numerous specimens were sent to me for determination by Mr. 8. Nacasawa. In October 1906, Messrs. T. Kawaxamt and U. Mort made another excursion to the same mountain, and collected quite a number of plants. Another ascent of the same peak was made by Mr. G. Nakanara who had equal success. Other mountainous districts of Taito and the central ranges were botanically explored by Mr. U. Morr in the same year. Some parts of the hill regions of Taihoku, Taichi, Tainan and Koshiin have been little by little botanized for some years; but the greater part of the island remains as yet unex- plored. All the determinations of the species have been worked out by me; but a few families with which I am not yet thoroughly acquainted are almost entirely omitted in the present paper.

Although the materials here treated are rather limited and further exploration will reveal many new features, the present work will, | hope, throw some light upon the study of the montane flora of the island. In conclusion, I wish to tender my sincere thanks to Prof. J. Marsumura under whose oversight this work has been ecar- ried out. Thanks are also due to Messrs. T. Kawaxamr, S. Na- GasawA and G. Naxanara, who all have generously put their im- portant collections at my disposal. Lastly, I desire to express my cordial gratitude to Mr. N. Konisar whose valuable collections have enabled me to make most interesting discoveries on Conifere and Quercineee. A new species of Conifers is named Cunninghamia Konishii in recognition of his kindness. March 14th., 1908. B. Hayara, Botanical Institute, College of Science, Tokyo. 4 ART.: 19.—B. HAYATA: 1.)

Morrison, the highest peak of the Japanese Empire. This mountain, lying a little within the tropic of Cancer, attains a height of 13,120 ft. It presents various climatal features from tropical through temperate up to those of cold regions, and in winter snow is frequently seen on the summit. The term flora used in this work includes flo- wering plants, ferns and their allies. The lower cryptogams are entirely omitted. I have enu- merated 892 species be- longing to 79 families Most are and 266 genera. of the northern elements. species FLORA MONTANA FORMOS® 5 It is a very interesting matter to compare this flora with the floras of the neighbouring countries, and to consider ‘their relations. So far as I am aware, no attempt of this kind has yet been made. In the year 1905, I published a paper” “ On the Distribution of the Formosan Conifers” in which I pointed out that the flora of the Conifers of Formosa has a far closer relation to that of Japan than to that of China, regardless of geographical proximity. In this paper, I have compared all families of flowering plants in the montane zone, and found that the conclusion I had made from the study of Conifers holds good for the general features of the flora. I shall refer to this matter later on. Before we go further in the discussion of this interesting subject, it is necessary to consider the elements of the montane flora. eececevolesescetoreres Silene Fortunei Vis.

The occurrence of this genus, which is all but peculiar to the flora of Tropical America, is exceptionally remarkable. It is perhaps the most anomalous case we meet with in the Formosan flora. This genus is here represented by a large tree, Oreopanax formosana Hayata. As far as I am aware, we have had no representative of this American genus in any other region on the globe. The tree is found in the mountainous districts on the north-western side of the central ranges, and also on Mt. Morrison, both localities having elevations varying from 6,000—8,000 ft. As the plots are quite inaccessible, it does not seem probable that the tree was planted there by human agency. eé) Malay Elements. These elements are rather less numerous. There are in all 98, or 25% of the whole number mentioned in the list. Among them, we have 45 tropical elements or 12% of the whole number. None of these species ascends to an altitude higher than 3,000 ft. An exceptional case is that of the tropical genus, Heptapleurum, which is found at an elevation of about 7,000 ft. f) North American Elements. These elements are comparatively well represented in this flora. As has been seen in the foregoing list, we have as many as 37 species, or 9.5% of the whole number. Of these American representatives, almost no species, except a very few cosmo- politans, extends any farther south than Formosa, not even to _ FRE WS FLORA MONTANA FORMOSE 25 Luzon. It is, therefore, certain that the flora under consideration has a far closer affinity to that of North America than the flora of the Philippines has to that of the new world. It is very interesting to notice that the montane flora has some genera which are found in North America, North China, and Japan, but nowhere else. They are :— Mitella (Formosa, J apan, North China, Siberia, and North America). Chamecyparis (Formosa, Japan, and North America). Pseudotsuga (Formosa, Japan, and North America). g) Himalayan Elements. These elements are here represented by as many as 101 species, or 26% of the whole number. Most of them are found in Japan and also in China. Those plants which are confined to Formosa, the Himalayas, and China are as follows :— Arabis alpina Linn. Thea caudata (WaAtt.) Oxalis Grifithii Enarw. America, and Africa) Desmodium sinuatum BuvuMe. Steller, Chamejasme Lrxn. Juniperus communis LINN. (repre- sented by J. formosana Hayarva. Peliosanthes courtallensis Wiaur.

Those plants, which are found in the Himalayas and Formosa, but nowhere else, are :— Ayrabis taraxacifolia ANDERS. Castanopsis indica A. DC. Epilobium alpinum Lixn. (also in Lunda spicata DC. Europe). Agrostis Clarket Hoox. f. Lecanthus Wightii Wevp (also in the Isachne Clarkei Hoo. f. Malay Archip.). 26 ART. 19.—B. HAYATA: h) Elements of central and southern China (ineluding Tibet). This is the class best represented in the flora, comprising as many as 192 species, or 49%¢ of the whole number. Most of them are also found in Japan. The plants which are confined to this region and Formosa, are as follows :— Heckia Aschersoniana EFNet. et Salvia scapiformis HANce. GREBN. Daphne Championi BENTH. Senecio monanthus DrIEs. Libocedrus macrolepis BENTH. Petasites tvicholobus Francu. ° Pinus Armandi FRANCH. Gentiana humilis Srey. Keteleeria Davidiana BEtssn. They are in all 9 species, among which we have 2 genera, Hackia and Keteleeria, which are found in this region and Formosa, but nowhere else. Here we see that the strong affinity between the two regions is as clearly shown by the plants of peculiar character as by the number of the elements. t) ‘Fapanese Elements. The Japanese elements are, next to the Chinese, best re- presented in the flora. They comprise in all 163 species or 42% of the whole number. The plants, which are known to exist only in Formosa and Japan, are as follows :— Clematis lasiandra Maxm. Lysimachia sikokiana Mia. Mitella japonica Mia. Conandron ramondioides S. et Z. Trochodendron aralioides 8. et Z. Tsuga diversifolia Maxim. Fatsia Pseudotsuga japonica SATRASAWA. Galium brachypodium Max. Abies Mariesii Masvers.

Chamecyparis obtusa 8. et Z. Pinus parvifloraS., et Z. (represented by P. formosana Hayata.) They are in all 16 species, among which we have some genera which are all but peculiar to Japan and Formosa. They are aS many as 4 genera :— Trochodendron Conandron Fatsia Metanarthesium. The Japanese elements are, on the whole, a little less numerously represented in the Formosan flora than the elements of central and southern China, so far as the figures of the elements are concerned. We see, however, that the number of the plants peculiar to both islands far exceeds the number of those which are confined to the continent and Formosa. Origanum vulgare Linn., which ranges over high mountains of the northern hemisphere, is wanting in Japan. Luzula spicata DC., which spreads over the Himalayas, North America and the arctic regions, has not yet been found, in Japan. j) Elements of nortivern China (including Manchuria, Saghalien, Amurland, and east Siberia). These are the least numerously represented in the flora. They number 81 species or 219. of the whole. Those plants, which are only found in North China and the island, are as follows :— I8 ART. 19.—B.. HAYATA: Cerastium pilosum LEDEB. Rhamnus arguta Maxim. (represented by a variety.) Here we see that the relation is far less close. k) LEudenuc Elements (excepting varieties.) Endemic plants are comparatively numerous as is to be expected in an island. There are as many as 99 species, or 25% of the total number of the plants found in the high elevations. This richness in endemic plants seems to indicate that the island has been entirely separate from neighbouring countries since geological epochs. However opulent Formosa is in peculiar plants, the figure representing the number of the endemic species is not so large in the case of this island as it is in that of the Philippines.” This fact shows that the flora of Formosa is of continental character, while that of the archipelago is insular. The numbers of the plants of endemic character under each genera are shown in the following list.

The general features of the elements are shown in the follow- ing table. 30 ART. 19:——B. HAW ATAS: Temperate elements 320 = 81 % of the whole number Tropical elements 45 ev de Oe ss Sg Arctic, antarctic & alpine ay wk: ov elements oe ee i Total 392 =—100 % Thus, the flora is, in general, temperate, having as many as 320 species of temperate character, or 81% of the whole number of the elements. The total number of the species in the flora is 392, belong- ng to 79 families and 266 genera. 2) Floristic Relationship between Formosa and Neighbouring Countries. The numbers of the elements in the regions under comparison are shown in the following table. Regions Number of elements The Malaypen. & archip. The Himalayas Central & southern China Northern China Japan North America Endemic As shown in the above table, the island has the strongest affinity to central and southern China and Japan; next, to the FLORA MONTANA FORMOS.2 31 Himalayas; then, to the Malay peninsula and archipelago, and North China; and lastly, to North America. As to central and southern China and Japan, the com- parative strength of their floristic relationship to Formosa is not to be measured by the number of elements only; the character of the elements must also be taken into account. So far as the number of the elements is concerned, it appears that the most striking affinity obtains between the island and central and southern China. It is not so, however, when we compare those elements which give the flora its peculiar features. The comparison of this class of elements, which plays so important a part in the study of phytogeography, is worthy of special attention. As we have already seen, the species the distribution of which is limited to Formosa and Japan are far more numerous than those confined to Formosa and China. We have also observed that the number of the genera, which are found in the islands and nowhere else, is double that of such kinds in Formosa and China. When we consider these species of peculiar character, we are forced to think that the flora of Formosa has a striking affinity to that of Japan. And it is even more so, when the genera, Trochodendron, Fatsia, Conandron, and Metanarthesium are taken into account. Thus, I am much inclined to conclude that the montane flora of Formosa is nearest to that of Japan, regardless of geographical proximity to China. A few lines should be here devoted to the cause of this similarity between the islands.” It is a very remarkable fact that so many plants of peculiar character are found in both regions. 1) Japan and Formosa. ' h on ae 39 ART 9.5.) aL Aen AG. This fact has led me to think that these plants once ranged over all the continent but became extinct there, while they have still survived in the islands, owing to their insular conditions”. This opinion will, however, not satisfactorily explain why the plants, which are found still living in the islands, do not also survive in so sheltered a place as Tein-ling-shan”, where the flora is quite as rich as it is in Japan and Formosa. It is very reasonable to think that in the so called coast provinces of China, the disturbances were so severe as to destroy these inhabitants of peculiar character. But, why in the protected centre of China ? It seems to me that insular conditions are not the only cause of the floristic affinity of the two regions, (Japan and Formosa) and I have wondered if this affinity were not due to a land-mass or mountain chains, which are by some geologists conjectured to have existed between the islands in former ages”.” In my paper “On the Distribution of the Formosan Conifers”, I referred to the probable derivation of the coniferous flora of Formosa, and came to the conclusion that the floras of Japan and Formosa have been developed in the border regions of the former continent, the extention of which reached from Japan southwards to the Loo-choo islands as far as Formosa; while the flora of central China has been formed in the centre of the continent. 1) I am much impressed by the opinion of Mr. Warntace who made the following con- clusion in his “Island Life” ed-8, p. 404:—“It is clear, therefore, that before Formosa was separated from the mainland the above named animals or their ancestral types must have ranged over the intervening country as far as the Himalayas on the west, Japan on the north, and Borneo or the Philippines on the south; and that after that event occurred the conditions were so materially changed as to lead to the extinction of these species in what are now the coast provinces of China, while they or their modified descendants continued to exist in the dense forests of the Himalayas and the Malay Islands, and in such detached islands as Formosa and Japan.” 2) Direxs, L.—Flora von Central-China, in Engl. Bot. Jahrb. XXIX. pp. 169-659, 3) Hayara, B.—On the Distribution of the Formosan Conifers, in Tokyo Bot. Mag. XIX. pp. 43-61, FLORA MONTANA FORMOS.E oer Thus, I divided the Chino-Japanese flora into two florulee, one is the central florula, the other, the border florula. Regarding the present subject of the montane flora of the island, I see that my former conclusion will hold equally good of the formation of this flora. Taking all these cases into account, I have come to the conclusion that the similarity of the floras of Formosa and Japan may have been caused, on the one hand, by the existence formerly of a land-mass between the islands, and, on the other, by the same insular conditions caused by the depression forming the inner seas in more recent geological ages. 3) General Aspect of the Vegetation. The ‘vegetation of the montane zone of Formosa varies considerably according to the height. As Mt. Morrison presents various climatal features from subtropical through temperate up to cold regions, the vegetation of this mountain will give us a fair idea of the general aspect of the growth in the hill regions of the island. As I have already mentioned, a botanical excursion was carried out on the mountain by Messrs. T. Kawaxamr, S. NaGa- sawA and G. Nakawara, and a report” of the journey was published by Mr. T. Kawaxamr in the Tokyo Botanical Magazine. As his report is the only publication relating to that mountain, I take the liberty of drawing some descriptions from it. . It was on the 28th of October, 1905, that the party left Kagi, a small town on the north-western foot of the mountain. 1) Kawakami, T. :—Botanical Excursion to Mt. Morrison, in Téky6 Bot. Mag.

HAYATA* Passing over many hilly passes, they found themselves on an elevation of about 2,400 ft., where they saw a beautiful forest of Dendrocalamus” and Bambusa”. From a height of 38,000 ft. upwards, beautiful arbors of camphor” and Quercus” made a dense forest with a liana formation, and many epiphytes of ferns, orchids and mosses. In this forest, the undergrowth is also beautiful; large tree ferns”, graceful stellate ferns”, wild Musa”, Calamus, Alocasia?, all combining to form a glorious example of tropical vegetation. At the height of 3,700 ft., a pretty herb” of the Urtica family occurred plentifully, and on it two species’ of Balanophoraceze were found attached to the host. Further, at the height of 4,200 ft, the trees of various Querci densely covered the plot, while many climbing plants hanging from the top of trees made the forest still more beautiful. Ascending a little higher, they came to the boundary of the savage districts. In a grassy plot near by, they found an 14) 15) Adenophora, wild pinks™, and violets”, in full bloom.

At the height of 6,800 ft., a dark forest of Chamacyparis” was first met with. The Conifer was here wonderfully large attaining a diameter of even 10 ft. Intermixed with the tall trunks of the five leaved pine”, with the gregarious undergrowth of a pretty variety of bamboo, this Chamecyparis” occupies the greatest part of the Conifer regions and constitutes the most peculiar feature of the flora of Formosa. The vegetation of this kind is seen only in the mountainous districts of Japan, though the growth is there far less luxurious. This spot is, it is said, frequently haunted by deer® of the peculiar species of the Formosan fauna. The climatal features here were temperate. The thermometer indicated 59° F. The familiar Polygonum? (near P. Thunbergit), Smilacina®, and Rhus were all welcomed as old friends. The red tinted leaves of the Rhus twining about the trunk of the pine reminding them of the autumnal scenery of Japan. The season of flowers was past; still there remained a few flowers and some fruits. From the elevation of about 8,000 ft., a full sight of the peak was clearly obtained.

HAYATA: The present plant is in every respect very like Rhus Toxicoden- dron Linn., but differs from it in having densely bristled fruits. At first sight, this new species appears to be referable to Tricho- carpe, on account of its bristled exocarpium. Studying the plant carefully, I have found that it should be referred to Venenatw by reason of the mesocarpium and general characters of the fruit. The plant may better be placed between the two sections. Pistacia Linn. Pistacia formosana Matsumura, in Toky6 Bot. Mag. XV. p. 40; Matsum. et Hayata, Enum. Pl. Formos. p. 99, t. 9.

The present plant is, in all respects, like D. villosa DC. But, in this new species, the seed is always one in each pod and the standard has distinct spurs on both sides of the lamina. In these respects, I think the plant is specifically separable from D. villosa DC. The leaves of the specimen, upon which the above description is based, are of a thinly hairy form. Here is another form with villose leaves which are much smaller than the leaves of the other form. The villose form seems to be a young stage of the other. FLORA MONTANA FORMOSZE a | ~I Cajanus DC.

The type is rather of the alpine character, being found in high mountains of Asia such as the Himalayas, and those of Borneo and west central China. In my former paper above aod I referred this Formosan species to Potentilla leuconota Don. After studying more carefully, 1 found that there is a little difference between this and that. It is not, however, without hesitation, that I have deseribed it as a new variety. The present plant differs from the type mainly in the absence of whorled leaves at the base of an umbel.
