NEW OR NOTEWORTHY ORCHIDS 
lanceolate, acute, with the apex thickened and more or less 
triquetrous. Dorsal sepal 1 cm. long, similar to the lateral 
sepals, strongly convex, with the apex thickened and some¬ 
what semiterete. Petals 9 mm. long, about 1 mm. wide 
above the middle, linear-spatulate, 1-nerved. Labellum 
about 9 mm. long to the base of the column, free portion 
about 6 mm. long, 6 mm. wide, simple or widely and ob¬ 
scurely crenulate on the margin, cordate, apiculate, bi- 
callose at the base. Column 6 mm. long, arcuate, wholly 
adnate to the labellum, minutely denticulate at the summit 
behind the anther. 
Closely allied to Epidendrum difforme Jacq., from which 
it differs in the smaller flowers and different labellum. From 
E. firmum Reichb. f. it is clearly distinguished liy the outline 
of the labellum.

provided between the distant pseudobulbs with two or three 
loosely appressed tubular sheaths, which soon disappear

5 cm. long, fusiform, concealed when young by several rather 
closely appressed imbricating sheaths, 3-4-leaved. Leaves
