NEW OR NOTEWORTHY ORCHIDS 
1.6 cm. long, entirely concealed by two ample spathe-like 
scarious imbricating bracts which are sessile in the axil of 
the uppermost leaf. Lateral sepals 1 cm. long, about 3 mm. 
wide, very fleshy, ligulate-oblong, margin more or less 
revolute, apex acute. Dorsal sepal of similar texture, 
ligulate, subacute. Petals about 1 cm. long, 2.5 mm. wide, 
narrowly oblong, sharply reflexed at the tip, apical portion 
triquetrously thickened, acute. Labellum about 1 cm. long, 
distinctly 3-lobed; lateral lobes rounded in front, erect, 
closely oppressed to the column, much less thickened than 
the middle lobe, about twice longer than the column; middle 
lobe sharply deflexed or decurved, 6 mm. long, about 1.5 mm. 
wide, subterete or obscurely quadrangular, acute, rugose 
when dry. Disc callose beneath the column. Column about 
4 mm. long, fleshy, with the clinandrium entire. 
In general aspect this species suggests Epidendmm 
teretifolium Sw., from which it differs conspicuously in the 
structure of the labellum. [Fig. 1.]
