Root consisting of two distantly-placed, elongated and subcylindrical tubers, 
and a few thick, fleshy, white fibres, spreading from the long neck of 
the root. Stem scarcely more than 4 inches long. Leaves, those from 
the root, three or four, spreading, elliptical, entire, glabrous, of a firm 
texture, dotted, and having a thin, semitransparent border or margin:

partly sheathing, marginated. Spike terminal, conical. Bracteas linear- 
lanceolate. Flowers scentless. The three outer petals green, spreading, 
of these three the uppermost is broadly cordate, ribbed, the two lower

permost are oblong, curved laterally, and lying close to and forming a 
slightly concave helmet with the uppermost outer one: the lowest or 
lip pendent, tripartite, its segments linear-lanceolate, the lateral ones 
acuminate, the intermediate one shorter and blunt. Spur greenish,
