Stelis inaequalis is most clearly differentiated from 
S. glossula by the smaller leaves which average 2 cm. in 
length, by the smaller flowers and by the inapiculate 
termination of the lip. Lateral sepals 1 mm. long. Dorsal 
sepal 2-2.5 mm. long. Lip 0.5 mm. long, very fleshy, 
lightly pandurate with a deep, rounded depression in 
front, shortly bicarinate below the middle. Column 8- 
lobed at the summit with the stigmas confluent beneath 
the triangular rostellar process. In the specimens from 
Panama and Honduras the leaves are from 1.5—8.2 em. 
long and about 5 mm. wide. The peduncle and raceme 
together are approximately 5 cm. in length.

STUDIES REGARDING THE SYNONYMY 
OF THREE SPECIES FROM MIDDLE AMERICA 
Stelis ovatilabia Schlechter in Beihette Bot. Cen- 
tralbl. 36, Abt. 2 (1918) 446, nomen, and in Fedde Re- 
pert. 15 (1918) 211. 
Stelis cyclopetala Schlechter in Fedde Repert. Bei- 
hefte 19 (1923) 279. 
In 1918, Rudolf Schlechter described Stelis ovati- 
labia, a new species from Guatemala. The type specimen 
consists of a single plant collected in 1878 by Bernoulli 
and Cario. This species is exceptional among Middle 
American representatives of the genus in the relative 
lengths of the column and petals. The column is diag- 
nostic in that it is almost twice longer than the petals.
