A SCIENTIFIC EXPEDITION TO TEMENGOH. 17 
The river where rocky produced several plants which I 
had previously met with far up the Pahang river, such as Hy- 
grophila saxatilis, Pentasacme caudata, Ixora stricta narrow 
leaved variety, Nauclea purpurascens and other narrow leaved 
plants characteristic of the mountain torrent streams. 
Conspicuous trees in the forests by the rivers were Lager- 
stroenna floribunda, Pangiwm cedule, and the beautiful Hngle- 
hardtia reminding one of anash tree. Mullettva decipiens with 
its white flowers, was also conspicuous. 
In some parts of the forest, especially near old Semang 
clearings, were dense thickets of Phaeomeria vmperialis, the 
cultivated variety with a white not yellow edge to the lip. It 
grew sometimes in immense abundance mixed with Hornsted- 
tia megalochilus and Amomum uliginosum, and is no doubt 
introduced, being cultivated for its edible flower buds and fruits. 
Zingiber spectabile was very abundant and in splendid flower. 
In the more open woods Didymocarpi were poorly represented 
though what species there were were abundant. Among herba- 
ceous plants the Acanthaceae were most abundant, and con- 
spicuous. ‘The sandy woods seemed to suit these plants very 
well. The most striking was a fine Strobilanthes with violet 
flowers. Orchids and indeed epiphytes generally were con- 
spicuously scanty, in most of the woods and along the river 
bank. Perhaps the country was apt to get too dry for them. 
Palms too were by no means as abundant as one usually finds 
them in hillwoods, and did not as usual form an important 
feature in the landscape. 
I expected to find so far north the ricefield flora of the 
northern part of the peninsula but the rice cultivators had 
come from the south, and with them had come the southern 
ricefield weeds. The fields were often edged with the Willow 
Salix tetrasperma. As this is often used further south as a 
kind of hedging or fence for the fields it may owe its abundance 
in such spots to introduction. 
‘Near the village the little river known as Sungei Kertai 
runs into the Temengoh river and on one occasion the plant 
collector and I waded as far up the river or walked along the
