56 A SCIENTIFIC EXPEDITION TO TEMENGOH. 
Ophiorrhiza Mungos, L. said by King to be found in 
all the provinces, was based on a tall Ceylon plant, 
which does not closely resemble anything I have seen 
in the peninsula, and not at all the plant sent out by 
King as O. Mungos. 
I have a large series of the Malay peninsula species 
in the Singapore Garden Herbarium and find they 
sort out to a large extent according to districts in 
which they occur, and thus are probably specifically 
distinct. 
O. erubescens, Wall. Temengoh Woods. 
Mussaenda oblonga, King. An erect bush in forest by the 
river, Ulu Temengoh. 
M. glabra, Vahl. Apparently quite absent at Ulu Temengoh, 
seen only further down the river near Kuala Temengoh 
in old village sites. 
Urophyllum macrophyllum, Korth. 'Temengoh woods. 
U. corymbosum, Korth. Ulu Temengoh woods. I certaintly 
think this should be kept as a distinct species from 
U. macrophyllum of which King and Gamble make it a 
variety. 
U. glabrum, Wall. Temengoh. 
U. streptopodium, Wall. var glabrum, Temengoh woods. This 
form resembles typical U. streptopodiwm but is quite 
glabrous. 
Adenosacme. longifolia, Wall. A malayana, Wall. Temengoh 
woods. 
There are two forms of this plant readily distinguish- 
able in life but difficult- to separate from herbarium 
specimens. One is the white flowered form of the plains 
and of the south of the peninsula, occurring in Singapore 
and Johor. The other is more of a mountain plant 
with conspicuously yellow flowers. This is the Te- 
mengoh plant, which is also a rather exceptionally hairy 
Jour. Straits Branch
