NKW OR NOTEWORTHY ORCHIDS 
raceme. Bracts of the raceme approximate, 1.5 mm. long, 
obliquely infundibuliform, scarious, with the points of in¬ 
sertion about 2 mm. apart. Pedicels about 3 mm. long. 
Lateral sepals 1.75 mm. long, 1.75 mm. wide, ovate, acute, 
very fleshy, sometimes lightly carinate along the middle 
on the outer surface, 3-nerved. Dorsal sepal similar. Petals 
hardly 1 mm. long, .75 mm. wide at the tip, narrowly 
flabelliform, triangular across the thickened apex, very 
fleshy, strongly cucullate, 3-nerved. Labellum scarcely 
1 mm. long, about 1 mm. wide across the middle, cucullate, 
obtuse at the apex, with the margin more or less erect, 
rhombic in outline, with a transverse thickening across the 
middle. Column dilated upward, with the posterior part of 
the clinandrium obscurely 3-lobed. 
Stelis cucullata is a close ally of S. perplexa Ames, from 
which il differs in part in having differently shaped, smooth 
sepals.
