crenulate above the middle on the anterior margin. Lip 
lingulate, lobulate-dilated on each side near the base, ses- 
sile, broadly rounded at the apex, 8-nerved, slightly cren- 
ulate above, about 3.5 mm. long, 2 mm. wide near the 
base, about 1.6 mm. wide near the apex; dise papillose 
above the middle especially toward the apex, with a pair 
of low slightly converging keels near the middle. Column 
about 2 mm. long, uniformly membranaceous-winged 
above the base; rostellum suborbicular, convex, decurved. 
A collection of this species in the herbarium of the 
New York Botanical Garden ( Shafer 9048 ) is apparently 
in a more advanced condition than the type, for it has 
generally longer leaves (reaching 23 mm. in length) and 
very mature perianths on the summit of the ovoid ovaries. 
The nearest ally of P.obliquipetala appears to be P. 
semperflorens Lind|. which differs in having elongate pe- 
duncles, and about twice smaller flowers with broader 
dorsal sepal, dissimilar petals and different lip. Vegeta- 
tively it suggests P. bicristata Cogn., P.calcarata Cogn., 
P.cryptantha Cogn. and P.mornicola Mansf. 
Pleurothallis obliquipetala was sent and tentatively 
described (but not published) by Dr. J. Acuna of Santiago 
de las Vegas, Cuba.

In an interesting collection of Costa Rican orchids 
sent by Manuel Valerio, there is a specimen referable to 
this species. It apparently differs from the type in sever- 
al particulars. The inflorescence is terminal only (not
