ORCHIDACEAE QUAEDAM AMERICANAE 
Terrestrial herb represented in the type collection by 
leafless scapes 24-25 cm. high which are thickly beset with 
approximate scarious sheaths 3-4 cm. long, tinged with 
pink-purple, internodes where revealed glandular-pubescent 
with hairs canescent and weak. Raceme 6-9 cm. long, up 
to 6 cm. in diameter; rachis and ovaries densely glandular- 
pubescent. Bracts of the inflorescence about 2 cm. long, 
lanceolate, acuminate, acute, scarious. Ovary shortly pedi¬ 
cellate, about 2 cm. long, obliquely ascending, somewhat 
arcuate. Lateral sepals decurrent on the ovary, forming 
an obtuse glandular-pubescent mentum, including the men- 
tum up to 22 mm. long, 4.5 mm. wide near the middle, 
oblong, tapering very gradually to the obtuse tip, glandular- 
pubescent on the outer surface, ascending, then sharply 
bent and protruding. Dorsal sepal with the adherent petals 
forming a strongly concave hood above the gynostemium, 
1.8 cm. long, narrowly elliptic, glandular-pubescent, obtuse, 
lightly carinate at the tip on the exterior surface. Petals 
about 1.8 cm. long, 2.5 mm. wide near the middle, oblong, 
obtuse, slightly tapering toward both ends. Labellum 3 cm. 
long, subequally 3-lobed at the tip, tapering to the sagittate 
base; lateral lobes semiorbicular, 5 mm. long, 3 mm. wide; 
middle lobe semiorbicular, about 4 mm. long, 7 mm. wide, 
rounded in front; limb of the labellum puberulous near the 
margin both on the inner and outer surface; basal auricles 
about 3 mm. long. Gynostemium slender below the stigma, 
puberulous on the inner face. 
Similar to Sarcoglotiis Smithii (Reichb. f.) Schltr. in 
general shape of the labellum. Sarcoglottis lobata (Lindl.) 
Baxt. is also a close ally, but the sagittate base of the label¬ 
lum different.
