crinita, and numerous herbaceous plants, many of them belonging to 
temperate genera and usually with conspicuous flowers, among 
which Lilium nepalense, Drosera peltata, whose small white flowers 
dot the grass in all directions in July, Sonertla Kerri, Valeriana 
Hardwickii, Swertia pulchella, and Paris polyphylla may be men- 
tioned. There are no woody climbers but many of the trees are 
loaded with orchids and ferns, the commonest being two species of 
Bulbophyllum, Cirrhopetalum papillosum, Coelogyne  siamensis, 
Dendrobium bellatulum and Pholidota obovata, 
At or near the top of the mountain, where the ground is fairly 
level and the humus can collect, we find the most luxuriant vegeta- 
tion to be seen on the whole of Doi Sootep, every bit of available 
space being occupied by plant life. The trees, Pyrenaria camelliae- 
ora, Adinandra integerrima, Litsaea salicifolia, and very many 
others I have not collected, are of medium size and their stems are 
clothed, as are the numerous lianes, with epiphytic mosses, ferns, 
asclepiads, gesnerads, orchids and ericaceous shrubs. The ground 
flowered Rhododendron Veitchiannm are the commonest of the 
epiphytic shrubs. Many of the trees are also burthened with immense 
masses of the orchid, Otochilus alia, other orchids here worthy of 
mention being Monemeria barbata, Eria barbata, Dendrobium bica- 
‘meratum, Dendrobium Falconeri, and Dendrobium ochreatum. 
Clearings are frequently made lower down at from 2000 to 
3000 ft. for the cultivation of mountain rice. These clearings, 
growth of a small tree, Trema amboinensis. A secondary growth 
of bamboo, common in other districts, is not often seen on 
Doi Sootep. In time, no doubt, most of these clearings return 
to the original jungle. 
I have attempted to sketch only the leading types of vegetation 
on Doi Sootep, but many others are to be met with, such as open 
marshes and evergreen swamps. In many places, too, the types of 
vegetation I have described are found more or less intermixed,
