TROPICAL AMERICAN ORCHIDS 
cate above and conspicuously carinate beneath. Inflores¬ 
cences nodding, densely many-flowered, about 13-21.5 cm. 
long. Peduncle stout below, with ovate-triangular cucul- 
late amplexicaul sheaths which are two to five in number. 
Raceme about 10-15 cm. long, 2-2.5 cm. in diameter in the 
dried state. Floral bracts very narrowly triangular-lanceo¬ 
late, nervose, the lower ones subequaling the pedicellate 
ovaries which are 7 mm. or less long and are reflexed. Perianth 
widely spreading. Sepals strongly cucullate with involute 
margins. Lateral sepals connate into a lamina which is 
bidentate or bifid with strongly reflexed apices; blade when 
expanded about 8-9 mm. long, about 4 mm. wide in the 
middle. Dorsal sepal fornicate, when flattened about 9.2- 
10 mm. long, 2.3-3 mm. wide when unrolled, oblong-lanceo¬ 
late, acute, with very slightly recurved tip. Petals entirely 
white, obliquely linear-oblong, 7.6-8.4 mm. long, about 1.6 
mm. wide, lightly falcate, complicate-mucronate at the 
apex. Labellum broadly trulliform, 6.3-7.1 mm. long (in¬ 
cluding the short claw), 4-4.9 mm. wide near the base, 
abruptly acuminate, with complicate margins; claw short, 
about 1 mm. long, with a callose keel above which extends 
through the lower portion of the lamina, obliquely inserted 
on the column. Column characteristic of the genus, gla¬ 
brous, tapering from a stout base, about 4.9 mm. long. 
Noiylia latilabia is allied to N. tamaulipensis Reichb. f., 
but the flowers are of markedly different color and are 
apparently larger and have a dissimilar lip. N. multiflora 
Hook, differs from N. latilabia in having flowers of a dif¬ 
ferent color, broader petals similar to the sepals, and a nar¬ 
rower lip. 
Panama, Frijoles, C. W. Powell 406, April 1924. Sea 
level. Grows in full sunlight, usually on Calabash trees. 
Flowers: Sepals Orange. Petals white without the orange 
dot on them characteristic of N. pentachne Reichb. f. (Type 
in Herb. Ames No. 28220.)
