360 MR. H. N. RIDLEY ON THE FLORA OF THE 
Malay Peninsula іп the ‘Flora of British India,’ but it is quite common, though local. 
Usually very plentiful where it occurs. I have it from Kranji, Toas, &c., in Singapore, 
where it grows on trees near mangrove-swamps, and from Kwala Lumpur caves in 
Selangor, collected by Mr. Kelsall, a similar locality to that of Kota Glanggi. There is 
also a sketch of it in Scortechini’s drawings. 
The flowers are of a pretty apricot-orange. 
PLATYCLINIS LONGIFOLIUS, Benth. 
This plant, which is common in Singapore and elsewhere, is not recorded in the 
‘Flora of British India? I saw what were evidently plants of it out of flower growing 
with other orchids on bougbs of Dipterocarpee overhanging the River Tahan. The 
Singapore plant was identified for me by Sir Joseph Hooker. It was originally described 
in the ‘Botanical Register’ by Lindley from living plants sent by Cuming from the 
Philippines. It was stated there to have green flowers; however, the petals and sepals 
are yellow, and the lip is brown. 
DENDROBIUM ($ BoLBODIUM) PUMILUM, Roxb. 
A very common little plant. Pekan, Pramau, Kota Glanggi, &c., growing on 
orchard trees, bushes on the heath country, and in more open woods. Both 
the yellow-flowered and pink-veined varieties are equally common, and often grow 
together.

Tahan woods. 
The flowers of this plant are whitish with pink veins, the base of the lip deep maroon- 
pink, the terminal lobes orange. It is very common in Singapore, and indeed elsewhere. 
The flowers remain open only about six hours. 
The species of this section are very troublesome to make out from dried specimens. 
The pseudo-bulbs, which give good characters, are crushed in drying, so that one cannot 
be sure whether they were flat or round. Тһе flowers are thin in texture, and easily 
crushed out of shape, and are, moreover, very short-lived. "The only way to study these 
plants is to cultivate them, when one can usually with ease obtain flowers fit to dry. 
It is not common to find them in good condition in the jungle. There are only two 
“Species mentioned from the Peninsula in the * Flora of British India.’ I have five or 
six more, very distinct ones. |
