lateral and terminal), the sepals are 5-nerved rather than 
8-nerved, the petals are acute rather than acuminate and 
the subquadrate lip (which is scarcely pandurate when 
expanded) is about 10 mm. long from the auricles of the 
deeply cordate base and about 12 mm. wide below the 
middle. The ovary appears to be definitely fusiform.

C, a-c. 
A drawing of the habit with a floral analysis of Oncid- 
tum cabagrae made under the supervision of Dr. Schlech- 
ter shows no appreciable differences from O. Rechinger- 
zanum as illustrated by a photograph of the type and a 
floral analysis (l.c.) made by Dr. Krinzlin. Slight differ- 
ences consist in the somewhat smaller leaves and nodding 
upper part of the raceme of O. Rechingerianum. 
A flower from the type of O.cabagrae (kindly sent 
by Dr. R. Mansfeld of Berlin) seems to resemble not only 
the analysis of typical O. Rechingerianum, but also a large 
series of Costa Rican specimens referred to that species. 
In this flower the dorsal sepal appears to be somewhat 
smaller than specified for O.cabagrae and to approach in 
size that of O. Rechingerianum. Moreover, the callus at 
the base of the lip appears to be reduced to an oblong 
thickening extended into an apical pair of lobules thus 
differing from the typical form of O. Rechingerianum. 
Apparently O.cabagrae is a rather variable species 
with the variation shown in the size of the plant, the 
breadth of the leaves, the strictness of the inflorescence, 
the size of the floral segments, the lobing of the callus
