ORCHIDACEAE QUAEDAM AMERICANAE 
base, obliquely ascending 2-2.5 cm. apart on the rhizome, 
diphyllous. Leaves 13-14 cm. long, 7-10 mm. wide, linear- 
oblong, obtuse, conduplicate at base, coriaceous, divergent. 
Peduncle abbreviated, with the raceme 1 cm. long, few- 
flowered. Floral bracts about 3 mm. long, subacute or 
obtuse. Pedicellate ovary about 9 mm. long, ascending. 
Lateral sepals about 1 cm. long, 2-2.5 mm. wide, narrowly 
triangular-lanceolate, acute, carinate at the apex, very 
fleshy. Dorsal sepal 9 mm. long, about 2 mm. wide near 
the middle, ligulate, tapering gradually from about the 
middle to the acute thickened tip, very fleshy. Petals 8.5-9 
mm. long, 1 mm. wide above the middle, spatulate from 
a slender base, acute, with a median purple stripe, some¬ 
what carinate near the apex. Labellum 9-10 mm. long, 
5 mm. across the middle when spread out, ovate, acute, 
strongly concave, whitish with a few longitudinal pur¬ 
plish stripes, very fleshy in texture, margin hardly undu¬ 
late. Disc with a thickening on each side above the base, 
otherwise ecallose. Column about 5 mm. long, fleshy, 
with a triangular erect lobule on each side at the summit 
and a posterior elongated linear tooth which is erect and 
1 mm. long in a line parallel to the axis of the column. 
Closely related to Epidendrum abbreviatum Schltr., 
which, from sketches preserved in my herbarium, is more 
slender in habit, with a rather orbicular than ovate labellum, 
more broadly spatulate petals, and a different column.
