Dendrochilum pubescens L.O. Williams sp. nov. 
Herba epiphytica, usque ad 2.5 dm. alta. Folia oblan- 
ceolata, acuta, fulvo- vel nigropubescentia, septemnervia. 
Inflorescentia folium superans; bracteae nigropubescen- 
tes. Sepala lanceolata, acuta, paulo carnosa, dorso paulo 
pubescentia. Petala oblongo-lanceolata, acuta, paulo car- 
nosa, obscure crenulata. Labellum oblongo-ovatum, acu- 
tum, integrum sed parte inferiore paulo laceratum, car- 
nosum, tricallosum. Stelidia prope columnae medium 
stant. 
An epiphytic herb up to about 2.5 dm. tall. Pseudo- 
bulbs ovate, suleate when dry, about 2.5 em. long and 
1 em. thick; young floriferous pseudobulbs small, sub- 
tended by several pubescent chartaceous sheaths. Leaves 
oblanceolate, acute, shortly black- or brown-pubescent on 
the back, slightly less pubescent on the upper surface, 
with three prominent and four less prominent nerves, 
about 25 cm. long and 8.5 cm. broad above the middle. 
Flowering peduncle evidently surpassed by the mature 
leaves but surpassing the subtending leaf, black-pubes- 
cent. Bracts of the inflorescence black-pubescent, about 
5 mm. long. Dorsal sepal lanceolate, acute, somewhat 
fleshy, sparingly pubescent on the dorsal surface, 7-8 
mm. long and 8-3.5 mm. broad. Lateral sepals similar 
to the dorsal sepal. Petals oblong-lanceolate, acute, some- 
what fleshy, obscurely crenulate, about 6 mm. long and 
2.5-83 mm. broad. Lip oblong-ovate, entire but the lower 
half more or less lacerated, acute, fleshy, about 5 mm. 
long and 2.5-8 mm. broad; near the base of the lip is a 
large thickening which has two lateral ridges. Column 
about 8 mm. long; stelidia near the middle of the col- 
umn, acute, about 1 mm. long; rostellum prominent, 
triangular. 
Dendrochilum pubescens has no near allies in Borneo 
with which it is likely to be confused. It may be distin-
