 Petals oblong, obtuse, 1 .5 mm. long, less than 1 mm. wide. Lip fleshy, some- 

 what hastate, obtuse, 1 mm. long, with ocellate cells along the crenuiate mar-

 Sciences, Manila, from Distr. Zamboanga, Mindanao, E. B. Copeland, 1905

I have not seen Acoridium bistortinn (Krzl.) Rolfe, but A. Copehnulii must 

 be closely allied to it according to the figure in Xenia Orchidacea, pi. 299, 

 fig. 1, 1-5, although the inflorescence is very different.
