ORCHIDACEAE QUAEDAM AMERICANAE 
abbreviated slender petiole, conspicuously marginate. Pe¬ 
duncles single or in pairs from the summit of a secondary 
stem, with the raceme about 1.5 cm. long. Bracts of the 
inflorescence tubular-infundibuliform. Raceme lax, about 
4-flowered. Flowers opening in succession, very delicate 
in texture, about 2 mm. apart, pink-purple. Sepals united, 
forming a 3-lobed calyx with the lobes caudate-tipped; lat¬ 
eral sepals or lobes 11 mm. long to base of column, about 
7 mm. long to the sinus, free portion triangular-caudate, 
4 mm. wide; dorsal sepal or posterior lobe opposite to the 
laterals 1 cm. long to the base of the column, triangular- 
caudate, free portion about 3.5 mm. wide. Petals narrowly 
triangular, acute, 3 mm. long in a line parallel to the dorsal 
sepal, .75 mm. wide near the point of insertion, rounded on 
the outer angle nearest the point of insertion. Labellum 
3-lobed; lateral lobes much larger than the middle one, 
similar to the petals, 2 mm. long, .5 mm. wide, rounded at 
base; middle lobe about .5 mm. long, longer than broad, 
porrect, obtuse. Column fleshy, short. 
A very distinct species among the Central American 
representatives of the genus, extraordinarily large flowers 
in conjunction with diminutive vegetative parts giving the 
plant a characteristic appearance. The united sepals in 
their relation to one another recall the flowers of Masdevallia 
Veitchiana Reichb. f. Lepanthes TuerckheimU Schltr. is a 
near ally, but much larger in its vegetative parts with a 
very different labellum.
