Here are also found dense forests with clinjMng plants of 

 3a%ihinia, Hibiscus, Anodendron, Hydrangea and many others. 

 Fauloiovia, Musa, and Pyrns are also to be found. Above elevations 

 of 6000 ft., forests of Trocliodendron araUoides are found. The 

 plant extends from Formosa through the Loo-choo islands as far 

 north as Jafuu. It grows most luxuriantly in this region of the 

 island on the boundaries between the conifer and broad-leaved tree 

 regions. The trunks are here so large as to attain a diameter of even 

 15 ft. These forests constitute one of the most peculiar aspects of 

 the vegetation of Formosa. Trees found in this region are as 

 follows :- 



Taoualo japonica Szys. 



Eitrya japonica ThCNB. 



Ti'ochodendroii aralioid-'s SlEB. et Zucc. 



Lllicium spp.

On the mountain ridges, which are very unfavourable for forest 

 growth, are found bushes of dwarf trees or areas of gramineous 

 plants. It is interesting to notice that in such grassy places Garices, 

 which are found plentifully in the regions above 10.000 ft., are very 

 few, or nearly none. 



■ The undergrowth of the forests in these regions is very luxuriant. 

 Here Alocasia macrorrhiza, Colocasia, Epipremnum, 31usa, and Calamus 

 Margaritae are all very beautiful. Shrubs commonly found in these 

 regions are as follows :- 



Stachyurus praecox SlEB. et Zuco. 



Thea brevistyla Hay. 



Skiininia spp. 



Enonyins Spraegmi Hay. 



Rubits pecliiieUiis Maxim- 



Aiicuba japonica ThUNB. 



Damnacanthns indicns Gaeets.
