CENTRAL AMERICAN ORCHIDS 
villose, clasping the base of the ovary. Flowers 5-10 mm. 
apart. Ovary densely glandular-villose, sessile. Lateral 
sepals about 7 mm. long, oblong-triangular, acute, forming a 
blunt mentum, densely glandular-villose on the external sur¬ 
face. Dorsal sepal 6 mm. long, 2 mm. wide, oblong, densely 
glandular-villose on the exterior surface, free from the 
petals. Petals 6 mm. long, about 1 mm. wide, oblong, obtuse, 
with several apical villi, 3-nerved. Labellum 8 mm. long, 
elongate-panduriform from a strongly concave or sub- 
saccate base, obtuse, glandular on the inner surface above 
the middle, apical margin involute; there is a thickened 
dentate callus — one on each side — situated on the 
margin near the base of the labellum. Column sigmoid, 
transversely complanate, produced obliquely downward on 
the summit of the ovary into a distinct foot, free portion of 
the column 2 mm. long, the foot 2 mm. long. Rostellum 
not at all produced. Anther inserted near the base of the 
free portion of the column, sagittate, long-stipitate. Pol- 
linia granulose. 
In habit not unlike Stenorrhynchus ceracifolius Rodr. 
{Cladobium ceracifolium Schltr.), but with more flowers in 
the raceme and a very different column.
