of the leaf. Roots fibrous, slender, glabrous, numerous. 
Leaves seven to eight, equitant, narrowly elliptic-oblong 
or narrowly oblong-lanceolate, up to 5 em. long and 1 
cm. wide, acute, spreading, articulated to oblong sheaths 
which are up to 2.4.cm. long, equitant, imbricating, and 
have scarious upper margins. Racemes reflexed or arcu- 
ate, up to 9 cm. long, sublaxly flowered nearly to the 
base; rachis densely glandular-pubescent, with the inter- 
nodes more or less fractiflex. Floral bracts widely spread- 
ing, broadly ovate to suborbicular, glandular-ciliate. 
Flowers small. Sepals thickly beset with stout glands 
on the outer surface and glandular-ciliate on the margin, 
flabellate-suborbicular, 1-nerved ; the lateral sepals slight- 
ly oblique and carinate with a lacerate keel on the outer 
surface, about 8 mm. long and equally broad above the 
middle. Petals similar, broadly obovate or cuneate-obo- 
vate, about 3.8 mm. long and equally broad above the 
middle, finely and irregularly ciliate, 1-nerved and cari- 
nate with a lacerate keel on the outer surface. Lip sim- 
ple, ovate, strongly concave above the middle with an 
involute tip, about 4.2 mm. long when expanded, about 
3.2 mm. wide below the middle, truneate or subcordate 
at base, acute, 5- to 7-nerved; disc fleshy-thickened and 
shortly papillose across the lower half, with the thickened 
margins of the basal half extending onto the lamina as a 
keel to a point slightly above the middle on each side. 
Column short, with a prominent recurved linear-lanceo- 
late rostellar process. 
A collection recently acquired from Mrs. Purdom is 
referable to this species. It differs from the type in hav- 
ing the shorter leaves ranging from asymmetrically ovate 
to elliptic-lanceolate. One flower shows a triangular- 
linear stipe bearing four subglobose pollinia at its dilated 
summit. 
Ornithocephalus cochleartformis appears to be allied to
