Orchis orbiculata, Pursu, Fl. N. Am. v. 2. p. 588. 
Root consisting of a few large subfusiform, thick, fleshy fibres. Leaves two, 
large, spreading, arising from the root, nearly orbicular, bright green, 
somewhat fleshy, indistinctly nerved, very obtuse. Scape about a foot 
high, simple, many-angled, naked, glabrous, terminated by a lax spike, 
from 4-6 inches in length, of yellowish-green, erecto-patent flowers. 
Bracteas lanceolate, nearly as long as the flowers. The three uppermost 
petals connivent, and including the anther, ovato-acuminate ; the outer- 
most ones the largest, green, the innermost rather shorter and yellower: 
the two lateral petals remarkably reflexed, so as almost to meet at the 
back, and to embrace the base of the spar and top of the bractea, their 
form is betweén ovate and lanceolate, and their colour green. Lip half 
as long again as the petals, linear-lanceolate, entire, yellow-green, stand- 
ing forward and incurved, the margins often reflexed ; its base prolong- 
ed into a spur, which is considerably longer than the germen, whitish, 
and hanging downwards. Anther large, green, triangular, the angles 
obtuse, cells distantly placed, linear-clavate, their bases much apart. 
Pollen-masses clavate, yellow, their glands standing out naked beyond 
the base of the cells. Stigma green, viscid. Germen } of an inch long, 
twisted.
