ORCHIDACE 
small group of Philippine Dendrochilum species which appears 
to be transitional between § Platyclinis and § Acoridium. The 
lateral arms or stelidia are apical, but have the aspect of being 
lobes of the terminal wing. 
The flowers are reddish-brown in dried specimens. The col- 
lector’s notes describe them as having been yellow in living 
plants. 
In fruiting specimens, surely referable to this species, the ma- 
ture capsules are spherical and about 8 mm. in diameter. 
The prominent marginal veins of the leaf are a conspicuous 
differentiating character between this species and D. bicalloswm.
