Notes on CLEOMELLA ; by Dn. Torrey. 
(From Memoirs of the American Academy of Arts and Sciences, N. S. vol. iv. p. 11) 
This genus was founded by De Candolle, on an unpublished drawing 
of a Mexican plant, of which specimens seem to be almost unknown 
in European herbaria. The description of De Candolle is brief and 
unsatisfactory. It was with doubt that I referred to his Cleomella 
Mexicana a plant found in Western Arkansas by Dr. James, in Long's 
first expedition. "The latter plant was afterwards detected by Mr. 
Drummond, in Texas, and by Mr. Beyrich, on the Upper Platte. It 
was described and figured by Sir William Hooker, in the first volume 
of his * Icones,’ as C. Mezicana, and described under the same name in 
the * Flora of North America,’ as well as in the recent * Genera Ilustrata’ 
of Dr. Gray. Another species of the genus was discovered by Colonel 
Fremont, in California, and published in his second report. About 
three years ago I received from Dr. Halsted excellent specimens of a 
Cleomella, which he collected on the march of our army from Vera 
Cruz to the city of Mexico. This is probably the original species of 
De Candolle, as it seems to be exclusively Mexican, while the Cleomella 
of Texas and Arkansas has not been found beyond those States, except 
in their immediate borders. I have, therefore, changed the name of the 
latter plant. A fourth species of the genus was discovered by Dr. Gregg, 
. in Chihuahua and San Luis Potosi, in 1847 and 1848. The following 
. synopsis will exhibit the leading characters of all the species.

"This species is about a foot high, much branched, and apparently 
diffuse. The leaflets are about one-third of an inch long, quite 
glabrous, somewhat fleshy, and mucronate with a short bristle. The 
petiole i is about as long as the leaflets. Stipules minute, subulate and 
entire. The golden-yellow flowers are in terminal racemes, which are
