308 Synonymy of some North American Orchidaceae. 
of Mr. Brown and Mr. Bennett, I may state that a minute exami- 
nation of the specimen on which this species is founded, proves it 
to be identical with the well known Habenaria herbiola. It is 
a somewhat loosely flowered form, with the stem rather naked 
above, exactly similar to those we often receive from the Southern 
States, as well as from Pennsylvania. The description of. Clay- 
ton is so far correct, that it is probable the pale or greenish-yellow 
flowers alone have prevented all succeeding botanists from sus- 
pecting it to be the Linnzan plant. -The specific name is cer- 
tainly not happily chosen for a plant of which Clayton observes, 
“ floribus obsolete luteis,” but it must nevertheless be retained. 
The-remarkable tooth or process on the upper side of the lip 
near the base, by which the plant is so well distinguished, is also 
unnoticed. I find the same species among the plants of Pursh, 
in Mr. Lambert’s herbarium, under the name of O. fuscescens. 
This last species was established upon a figure and description of 
Gmelin’s Flora Sibirica, which accord so well with the American 
plant, that, in the absence of specimens, I am unable to pronounce 
them dictions. The lip has the same lateral teeth, but, instead of 
the projecting process, Gmelin describes the posterior portion as 
“in cymbam fere excavata.’’ The inspection of Willdenow’s 
herbarium enables me to add:as a synonym the O. virescens of 
that author; of whose character: “cornu obtusum scrotiforme 
brevissimum,” it should be remarked that it is totally at variance 
"with his own solitary specimen received from Muhlenberg, under 
this name. The latter, in his unpublished Fora Lancastriensis, 
thus describes the lip and spur:—* Labio nectarii oblongo ematr- 
ginato indiviso et subtrilobo, vel basi utrinque dentato; cornu 
Setaceum germine brevius, acutum.” The synonymy of this 
Species, so far as already ascertained, may stand as follows.
