* [ have specimens of O. clavellata from Nuttal, marked on his ticket 
* O. tridentata,’ and on reference to his book I find he gives it as a variety 
of O. clavellata, not admitting, therefore, Michaux's plant * labello integro, 
as observed by himself. 
* Elliott quotes O. tridentata as a synonym of his O. clavellata, and, 
giving Michaux's character, as the specific one, says, from his own obser- 
vation, that the labellum is * slightly three-toothed at the summit.’ 
* Willdenow merely copies Michaux for O. clavellata. 
** I suspect, therefore, that there is an error in Michaux's description of 
the plant, viz. that he has overlooked the toothed extremity of the label- 
lum, and that his specimen was small, which his * scapo unifolio' leads me 
to suspect. 
* Eaton, in his Manual, gives O. tridentata as a synonym of O. clavellata ; 
and I observe in a Catalogue of Plants made in Kentucky by Dr. Short, that 
he has the O. tridentata, a situation near Elliott's habitat for his O. cla- 
vellata; viz. * the middle and upper districts of Georgia and Carolina.’ 
* All this amounts to a probability of the tridentata being the same as 
Michaux's plant. If distinct, it would seem no one has met with the true 
clavellata since Michaux, not even Elliott."
