38. RÆŒÆPEROCHARIS, Reichb. f. Otia Bot. Hamb. ii. 104. 
Sepals unequal, free, lateral somewhat spreading. Petals simple, 
free, much like the dorsal sepal. Lip continuous with the column, 
produced at the base into a spur; limb spreading or pendulous, 
simple or trilobed. Column very broad, footless; clinandrium diver- 
gently bilobed. Anther cells distant, terminating abruptly in front, 
without channels; pollinia granular, with short caudicles and exserted 
naked glands; staminodes lateral, transversely oblong. Stigmas de- 
scending in a pair of clavate-oblong processes, produced behind into 
a pair of tooth-like lobes ; rostellum with the middle lobe obsolete; side 
lobes descending in triangular lobes, confluent with the arms of the 
column above.—Krinzl. in Reichb. f. Xen. Orch. iii. 102, t. 258. 
An exclusively Tropical African genus of five species, differing from Habenaria in 
the remarkable structure of the column.
