ually to an acute tip, 1-nerved, somewhat concave, strongly 
divaricate, membranaceous. Dorsal sepal similar. Petals 
nearly 3 mm. long, 1.5 mm. wide near the middle, ovate, 
acute, 3-nerved, minutely ciliate on the margin, purplish, 
membranaceous, densely and shortly glandular-pubescent 
toward the base on the upper surface. Labellum 3.5 mm. 
long, 1 mm. wide, simple, oblong, gradually attenuated 
from above the middle to the acute tip, 3-nerved, retrorsely 
ciliate on the margin, densely and shortly glandular-pu¬ 
bescent on the upper surface. Column abbreviated, scarcely 
1.5 mm. long, stout, provided with numerous elongated

ceous, cordate. 
The nearest affinity of this species is Telipogon minuti- 
florus Kranzl. which is in part distinguished by 1-nerved 
petals and an ovate-triangular labellum. Both T. Lankesteri 
and T. minutiflorus represent aberrant species of Telipogon 
and may be members of the genus Stellilabium which 
Schlechter erected for the reception of Telipogon astroglossus 
Reichb. f. 
From dried specimens the flowers appear to have been 
purplish.
