ORCHIDACEAE QUAEDAM AMERICANAE 
acute tip. Raceme 11-22 cm. long, barely 2 cm. in diameter, 
many-flowered, buds and faded flowers simultaneously 
present; rachis glandular-pubescent. Bracts of the inflo¬ 
rescence glandular-ciliate on the margin, lanceolate, acu¬ 
minate, acute, 1 cm. or more long. Ovary shortly pedicellate, 
densely glandular-pubescent, about 9.5 mm. long. Lateral 
sepals decurrent on the ovary, scarcely 1 cm. long from 
tip to base of mentum, about 3 mm. wide, triangular-oblong, 
obtuse, 3-nerved. Dorsal sepal 6 mm. long, adherent to 
the petals and with them forming a deeply concave hood 
over the gynostemium, glandular-pubescent on the exterior 
surface, narrowly elliptic-lanceolate, obtuse. Petals about 
6 mm. long, falcate-lanceolate, obtuse, 3-nerved, glandular- 
ciliate on the outer margin. Labellum about 8 mm. long, 
sagittate at the base, constricted near the apex to form a 
suborbicular terminal lobe 2 mm. long and 3.5 mm. wide; 
lamina 5 mm. wide below the point of constriction, rounded 
above, gradually tapering to the wide sagittate base. Disc 
conspicuously glandular-hairy below the middle; auricles 
nearly 2 mm. long, flattened, very fleshy. Gynostemium 
4 mm. long measured from the base of the dorsal sepal to 
the denticulate tip of the slender rostellum. 
Allied to Spiranthes Schaffneri Reichb. f., from which 
it differs in the 3-lobed labellum and absence of leaves at 
flowering time. From Sarcoglottis zamororae Ames it is 
distinguished by the glandular hairs on the disc of the label¬ 
lum and by the more strongly concave cucullate dorsal sepal. 
Mexico, C. G. Pringle 8867. (Type in Flerb. Ames 
No. 6648.)
