ORCHIDACEA 
trinervia, caudata. Sepalum dorsale 9 mm. longum, triangulari- 
lanceolatum, acutum. Petala minuta, 2 mm. longa, .75 mm. lata, 
oblonga, acuta, uninervia. Labellum vix 3 mm. longum, lingu- 
latum, trilobatum; lobi laterales erecti, rotundati; lobus medius 
oblongus, obtusus, callo oblongo in disco, minute verruculosus. 
Gynostemium antice bicuspidatum. 
Closely allied with Bulbophyllum hortense J.J. Sm. which has 
longer, looser racemes and very different flowers in which the 
lateral sepals are more caudate at the tip and less triangular. 
B. odoratum Lindl., another nearly related species, is in part dis- 
tinguished by its triangular sepals that are hardly, if at all, cau- 
date. Among Philippine species, B. hortensoides is most closely 
allied with B. leytense Ames, from which it differs in the struc- 
ture of the labellum. As in B. prianganense J.J.Sm., B. hortense 
J.J. Sm. and B. leytense Ames, the scape is concealed from 
its base to the lowermost flower of the raceme by conspicuous, 
ancipitous, imbricating, foliaceous sheaths. The elongated callus, 
rounded in front, that reaches almost to the apex of the mid- 
dle lobe of the labellum is of diacritical value in separating 
B. hortensoides from its Philippine allies. When highly magni- 
fied the sepals are pustulose.
