ly unicarinate, 4-nerved with the anterior nerve extend- 
ing only through the lower half. Petals ovate-elliptic, 
acuminate with a complicate apex, about 4.2 mm. long 
and 2.1 mm. wide, 3-nerved. Lip obovate in outline, con- 
‘ave, abruptly anchor-shaped-dilated near the broad apex, 
abruptly acute, shortly clawed, about 4 mm. long, 7- 
nerved; lower portion of lamina subquadrate, abruptly 
rounded at the base, about 2 mm. long and 2.1 mm. wide: 
unterior portion abruptly dilated with a short retrorse 
triangular-lanceolate lobule on each side, nearly 4 mm. 
wide when expanded. Column very short and stout, 
about 1.6 mm. long, with an inconspicuous erect shal- 
lowly rounded intrastigmatic process. Pollinia four, in 
two unequal pairs, complanate-subpyritorm. 
The habit of this species suggests a very slender form 
of Dichaea Powell Schitr., but the very narrow leaves 
and abruptly subquadrate basal portion of the lip are 
diagnostic. 
The description of the flower was made from a single 
(perhaps immature) flower in which the segments were 
connivent.
