CENTRAL AMERICAN ORCHIDS 
Roots elongated, fibrous, villose, the hairs white in 
dried specimens. Leaves basal, few. Petioles slender, 
3-4 cm. long; lamina of the leaf 7-8.5 cm. long, 4 cm. or 
more wide, membranaceous, broadly ovate from a rounded 
base, acuminate, acute. Scape with the raceme about 
22 cm. long, hairy above. Bracts of the inflorescence 
greenish, narrowly lanceolate, 4-7 mm. long, sparsely 
pubescent. Raceme nearly 4 cm. long, about 1.5 cm. in 
diameter. Pedicels about 1 cm. long, sparsely glandular. 
Flowers resupinate. Lateral sepals 5.5 mm. long, 3 mm. 
wide, elliptic-ovate, acute, glandular on the exterior surface, 
3-nerved. Dorsal sepal 5.5 mm. long, similar to the laterals. 
Petals 4.5 mm. long, 2 mm. wide, inserted on the base of the 
column, oblong, rounded at the tip, obtuse, upper margin 
long-ciliate. Labellum 5 mm. long, unguiculate, about 
4 mm. wide in front of the claw when spread out, hastate, 
rounded at the tip, long-ciliate on the margin of the apical 
third. Column 2.5 mm. long, fleshy, truncate at the sum¬ 
mit. Anther elliptical, fleshy. Pollinia elongated, slen¬ 
derly pyriform, attached to a round thickened disc. 
I have referred this species to Cranichis although in the 
structure of the unguiculate labellum it is dissimilar to the 
characteristic species of the genus. There are no near allies 
in the Central American orchid flora.

Racemus sublaxus. Sepala lateralia basi protuberantia, 
supra insertionem triangularia, extus glandulosa. Sepalum
