GYNANDRIA MONANDRIA* 
485 
From the O. Psycodes (judging from specimens sent me by Muhlenberg) 
this plant differs essentially. It is distinguished by a more scattered spike, 
and by every portion of the flower, germ, segments, and labellum, longer 
and proportionally narrower. 
Grows in the middle districts of Carolina. St. Stephen’s, Dr. Macbride.

and crenate; horn ta-

Stem about two feet high. Leaves narrow lanceolate, sheathing, the 
upper one small. Flowers in a short crowded spike, yellow. Bracteal 
leaves sometimes not longer than the germ. Exterior segments of the peri- 
anth larger than the interior; labellum lanceolate, the sides toothed or cre- 
nate, almost fimbriate. Horn subulate, generally shorter than the germ, 
nearly acute at the point. 
This is the O. Flava of Nuttall; it appears however, to differ much from 
the original O. Flava of Clayton, (“florihus in spica longa congestis; labio 
inferiore nectarii trifido; lacinia intermedia majore; calcare germine longi- 
ore.” Gron. FI. Vir. p. 137- 
Grows in the middle and upper districts of Carolina and Georgia.
