NEW OR NOTEWORTHY ORCHIDS 
8-10 cm. long, up to 1.6 cm. wide, oblong, abruptly nar¬ 
rowed at both ends, obtusely bilobulate at the tip, erect. 
Peduncle 4-5 cm. long, much exceeded by the leaves, about 
4-tlowered. Flowers in a loose raceme, white or cream color, 
the sepals and petals with a short median band of purple 
and the labellum with about twelve purple stripes. Bracts 
of the raceme about 4 mm. long. Pedicel with the ovary 
1.7 cm. long, ascending. Lateral sepals 2 cm. long, 4 mm. 
wide, narrowly lanceolate, acute, with a deep keel along 
the middle on the outer surface. Dorsal sepal similar, 
ecarinate. Petals 1.7 cm. long, up to 5 mm. wide, lanceolate, 
acuminate, acute. Labellum 1.5 cm. long, about 7 mm. 
wide below the middle, elliptic-ovate, acuminate, acute, 
lightly and shortly carinate on the under side near the tip. 
Callus velutinous, situated at the base of the lamina, ob¬ 
scurely 3-lobulate in fronl. Column 5.5 mm. long, ad¬ 
herent for about one half its length to the labellum, dilated 
upward, with a fleshy, triangular tooth on each side in front 
at the summit, and with an oblong obscurely tridenticulate 
ligule behind the anther. 
Epidendrum vagans is closely allied to E. radiatum 
Lindl. and E. ionophlebium Reichb. f. From E. radiatum 
it differs conspicuously in the outline of the labellum and in 
the well-developed keels of the lateral sepals. From E. 
ionophlebium it differs in habit, the leaves being much 
smaller and the pscudobulbs widely separated on the 
elongated, creeping rhizome.
