ENUMERATION OF SPECIES 
Oeceoclades alismatophylla (Rchb.f.) Garay & 
Taylor, comb. nov. 
Basionym: HMulophia alismatophylla Rehb.f. in Flora 
68: 5438, 1885. 
Syn.: Mulophidium alismatophyllum (Rehb.f.) Sum- 
merh. in Bull. Jard. Bot. Bruxelles 27: 894, 
1957. 
Type: Madagascar, Forét d’Ankaye. Coll. Humblot 
s.n.f (W). 
Distribution: Madagascar. 
Vegetatively the plants of this species are very similar to O. anala- 
merensis, O. petiolata and O. lonchophylla, but readily distinguishable 
from them in the floral structure, especially in the shape of the lip 
with the lateral lobes being larger than the median Jobe. We have 
seen only the type specimen. 
Oeceoclades ambongensis (Schltr.) Garay & Tay- 
lor, comb. nov. 
Basionym: HMulophidium ambongense Schltr. in Ann. 
Mus. Col. Marseille, ser. 3, 1: 182, t. 17, 
1913. 
Syn.: Hulophia Schlechtert H. Perr. in Bull. Soc. Bot. 
Fr. 82: 154, 1935. 
Lissochilus Schlechteri (H. Perr.) H. Perr. in 
Humbert, Fl. Madag. Orch. 2: 27, 1941. 
Type: Madagascar, Manongarivo (Ambongo). Coll. 
Perrier no. 1684! (P). 
Distribution: Madagascar. 
From the related species of the O. maculata alliance, the plants of 
this species are readily identifiable by the comparatively larger flow- 
ers, subglobose spur and the bilobed callus of the lip.
