ORCHIDACE.E 



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. bicallosum.
