CENTRAL AMERICAN ORCHIDS 
rotundata, conspicue uninervia, margine sparse ciliolata. 
Labellum basi profunde saccatum, antice in laminam con- 
duplicatam extensum. Columna generis. 
Terrestrial herb about 20 cm. tall, with nine or more 
leaves clustered at the base. Leaves petiolate, spreading; 
petioles up to 1.5 cm. or more long, sheathing the stem at 
base; lamina of the leaf membranaceous, 1.5-2.5 cm. long, 
up to 1.5 cm. wide, the smaller ones nearest the base of the 
stem. Scape with few bracts, glandular-pubescent above 
the middle, lowermost bract foliaceous, upper ones more or 
less closely oppressed, 1-2 cm. long, acute, glabrous. Ra¬ 
ceme ten or more flowered, exceeding 3.5 cm. in length; 
rachis glandular-pubescent. Bracts of the raceme oblong- 
lanceolate, not exceeding the ovary in length. Pedicellate 
ovary about 7 mm. long, densely glandular. Lateral sepals 
4 mm. long from the point of insertion at the base of the 
column to their tip, with a conspicuous rounded posterior 
protuberance which is 2 mm. long, triangular-acute above 
the middle, sparsely glandular-pubescent on the outer sur¬ 
face. Dorsal sepal 5 mm. long, 2 mm. wide near the middle, 
narrowly elliptical, obtuse, mid-nerve conspicuous. Petals 
about 4 mm. long, 1.5 mm. wide, elliptic-oblong, rounded- 
obtuse at the apex, median nerve conspicuous, lower margin 
obscurely ciliolate. Labellum 6 mm. long, deeply saccate, 
with the sac subcylindrical and blunt; lamina above the sac 
porrect, more or less conduplicate, obcuneate, truncate, 
4 mm. long, hardly 2 mm. wide when spread out, with a 
prominent erect callus at the base in front of the opening of 
the sac; basal margin of the labellum obscurely crenate- 
dentate. Column 3 mm. long. 
In the structure of the labellum Cranichis saccata differs 
from all other species in the Central American area. The 
protuberant basal portion of the lateral sepals is anomalous 
in the genus.
