Messrs Branner and Coville, at the place above cited, express 
themselves as uncertain of the applicability of the Linnaan name 
to this species. They have taken it up correctly, however, al- 
though it has had a curious history. The specimen preserved 
under the name Cardamine Virginica in the Linnzean Herbarium 
is Stsymbrium asperum, L. of Southern Europe, which bears a 
wonderful resemblance to the plant of the Southern United States, 
readily distinguishable, however, by its glandular. roughened sil- 
iques, those of the our plant being perfectly glabrous. The foli- 
age of the two species is practically identical. It is perfectly evident, 
however, from his description that Linnzeus had only the American 
plant in mind, and this is proved by the types preserved at the Brit- 
ish Museum of Natural History. I found no specimen of his Szsym- 
brium asperum except the one labelled Cardamine Virginica, 
in the Linnzean Herbarium, and it is clear that this one has been 
accidently fastened down to the wrong sheet.

This is another plant of this genus which I am sure deserves 
Specific rank. I pointed out the characters of Wallroth’s 4. m#- 
‘rocarpa in the BULLETIN, xviii. 367. The present plant, recog- 
nized as a variety by Torrey and Gray, has a slender canescent or 
pubescent stem, five to nine principal leaflets which are oblong 
or obovate, obtuse and equally dentate, small flowers and turbin- 
ate fruit, borne on erect, short pedicels and a glabrous, ribbed 
calyx 2 mm. high in fruit. ; 
We have it from Red River (Dr. Pitcher, the type specimen 
of the variety), Riverdale, N. Y. (Bicknell), Little Neck, Long 
Island (Schrenk), Heiligs Mill, N. C. (Small and Heller, No. 321). 
The North Carolina specimen has tuberous thickened roots, as
