minal, subumbellate raceme, 1- to 8-flowered, the abbre- 
viated peduncle being concealed by one (rarely two) 
broad spathes which are strongly conduplicate and apicu- 
late. Pedicellate ovary slender, fusiform above, 2-2.2 
em. long. Flowers rather small, reddish brown. Sepals 8- 
nerved, thickened toward the apex. Dorsal sepal oblong- 
ovate, subacute, about 10 mm. long, 5-5.8 mm. wide, 
with the margins (except near the apex and base) den- 
ticulate-erose. Lateral sepals obliquely oblong-ovate, 
sharply acute and mucronate, about 10 mm. long, 5—-5.8 
mm. wide, with the dorsal margin (except near the base 
and apex) denticulate-erose. Petals obliquely elliptic- 
oblong or rhombic-lanceolate, about 8.8 mm. long and 
3.7 mm. wide, obtuse, 8-nerved, with the upper margins 
denticulate-erose. Lip adnate to the column nearly to its 
apex; lamina deeply concave, simple, suborbicular-ovate 
or quadrate-ovate, lightly retuse at the apex, with the 
margins (except at the deeply cordate base) conspicu- 
ously denticulate, about 10 mm. long in greatest length 
and 10.2 mm. wide when forcibly expanded, with a pair 
of prominent complanate calli at the base. Column short 
and stout, dilated upward, produced on each side into a 
transversely subquadrate auricle, about 5.2 mm. long. 
Hpidendrum minutidentatum appears to be allied to the 
Colombian LZ. viridibrunneum Reichb. f., but its habit 
appears to be suberect and not creeping, the leaves not 
linear and acuminate and the petals not linear.
