APOSTASIACEE OF THE MALAY PENINSULA. 287 
DENDROCHILUM, Blume. 
Denprocuitum, Blume. The genus Dendrochilum was founded 
by Blume to include a number of plants which Bentham 
rightly separated into Dendrochilum and Platyclinis, the former 
including Blume’s Section 1 of Dendrochilum. To this section 
Lindley added a Madagascar plant which has long been referred 
to Bulbophyllum. 
Blume’s species were D. aurantiacum, with orange flowers, 
and D. pallideflavens, with pale yellowish flowers. 
Hooker (‘ Flora of British India’) gives three species from the 
Malay Peninsula—D. pallidiflorum, Blume (misprint for D. 
pallideflavens, Blume), D. linearifolium, Hook. f. (which from 
the Icones plantarum, fig. 1859, is, it appears to me, a Platyclinis) 
and D. bracteosum, Reichb. f., collected in the “ Malay Peninsula”’ 
by Finlayson. I have met with two more species, apparently 
undescribed, viz., D. crassum and D. album, mihi, and two 
others too incomplete for description, one a small species with 
narrow leaves and greenish-white flowers collected on Bukit 
Hitam, in Selangor, by Lieut. Kelsall, and another, with a much 
branched rhizome, thin-textured oblanceolate leaves, and very 
curious short three-lobed capsules, which I found without 
flowers on a tree far up the Tahan Valley, in Pahang.
