is said to occur near Keelung in the north but I did not see it. On Ape*s 

 Hill, Takao, the dwarf, endemic Phoenix TIanceana Naudin is abundant 

 and so too is Pittosporiim jormosanvm Hay., Scolopia crenata Clos and 

 Croton Cumingii Muell. Arg. Such littoral woody ])lants as Pandaniis 

 tectorius Soland., Scaerola Koenigii Vahl, Excoecaria Agallocha L,, Ilihis-

and widespread- A feature of the coral-cliffs round Takao is the curious 

 Euphorbia tinicalli L. with cylindric, whip-like branchlets. This succulent 

 Tree Euphorbia is considered to l>e a native of Africa, but it must have 

 been introduced into Formosa from China by early settlers- The seacoast 

 between Boryo and Koshun for many miles is covered with an almost pure 

 growth of Vitex .V^^z/n^o L., and near tide mark F. ara/a Thunb. abounds. 

 In the same district Hibiscus midabilis L., Klcinhoria hospHa L., Cerbera 



^^fi 



ifoUa Oliv. are features, and Indigofi 



cum L., 



ifolia L., Uraria crinita Desv. and 



Abrus prccalorius L. are wayside weeds. The low hills are clothed with 

 Acacia confusa Merrill and on the rocks Phoenix TIanceana Naudin groM's 

 in abundance but nowhere more so than at Taihanroku, a little seaport 

 village near Garambi, the South Cape of foreign maps. The Cape itself is 

 a bold headland of coral-rock, and inland from it rise curious pillars and 

 fortress-like masses of coral for the most part clothed with a Jungle-growth. 

 This region is hot and wind-swept and the \^egetation more tropical in 

 character than elsewhere in Formosa. In sheltered gullies I saw the gutta- 

 yielding Palaquium formosanum Hay. and the interesting Diospyros 

 Kusanoi Hay. and Z). idilis Hemsh; the latter has a large, apple-like, flat- 

 tened fruit covered with short liairs. The stinging Laportca pterostigma 

 ^Yedd. is common and so too are Sapindus mukorossi Gaertn., Gledilsia 

 formosana Hay., Cudrania javanensis Trccul, Melastoma candidum D. Don 

 and Ileptapleuritm octophyllum Benth. and many si^ecies of Tree Figs, Ilex, 

 Evonymus and Capparis, The region is very rich and I made a good haul 

 of specimens during my brief visit. At Pinan on the east coast I saw 

 little of interest except^ the Macartney Rose {R. bracteata WcndL) wliich 

 does not grow on the west coast though it is common in the adjacent coast 

 provinces of eastern China; it may be only an escape in Fonnosa. Near 

 Pinan and also near Giran in the north grows Koelreuteria formosana Hay, 

 which seems to be always a small tree. The flora of the inland valley 

 through which the road to Karenko leads is like that of the foothills and the 

 lower mountains and is both rich and vaiied. In places Pinus taiwanensis 

 Hay. reaches the valleys, and in the rock-strewn beds of shallow rivers and 

 summer-torrents Pyracantha Koidzumii Rehd. with its masses of scarlet
