Examples of the vegetation along valleys are shown in PI. 21 and 22.
Higher up the vegetation becomes less variable. Quercus and Lauraceous
plants mostly predominate , while Ficus gradually diminishes. The
cinnamomum forest is here most abundunt. Trees commonly found in this
foi cst are Lindera, Litsea, Tetradenia, Octea, Macliilus, various kinds of
Quercus, Castanopsis and a very few of Castanea. From an elevation of
3000 ft. upwards, beautiful arbors of Camphor and Quercus make a dense
forest, with a liana formation, and with many epiphytes of ferns, Crchids
and mosses. An aspect of the forest is shown in PI. 23.
Another example af this vegeta tion is seen in PI. 24. Here is found a
dense forest with climbing plants of Bauhinia, Hibiscus, Anodendron Hydrangea
and many others. Paulownia, Musa, and Pyrus are also to be found there'
Above an elevation of 6000 ft., there is found an entire forest of Troc/ioden-
dron aralioides. The plant spreads over from Formosa through the Loo-choo
islands as north as Japan. It grows the most luxuriantly in this region of
the island on the boundaries between the Conifer, and broad leaved tree
region. The t ru n k is here so large as to attain a diameter of even 15 ft.
This forest is one of the most peculiar vegetations found in Formosa. The
trees found in this region are as follows:

Cn the mountain ridge where it is very unfavourable for forest
growth, there are found bushes of dwarf trees or areas of gramineous plants.
It is interesting to notice tha t in such grassy places Carices, which are found
plentifully in the region above 10,000 ft., are very few, or nearly none, in this
elevation. An example of this grassy plot is shown in PI. 25. The under
The under growth of the forests in this region is very luxuriant. A
splandid example of this is shown in PI. 26. Here Alocasia macrorrhiza,
Colocasia, Epipremnum, Musa, and Calamus Margritae are all very be autiful.
