CARDAMINE PARVIFLORA L, Sp. Pl. Ed: 2,914. 1763. 
Common in dry upland woods about Knoxville, often appear- 
ing where the woods have been burnt over. 
Itza Virornica L. Sp. Pl. 199. 1753. 
Collected near Wolf Creek Station (no. 720), growing on a 
shaded ledge of sandstone along the French Broad River, an un- 
usual habitat for this plant, which ordinarily makes its home in low 
swamps. The specimens were small, the largest not more than 
I m. high, but seemed otherwise typical. 
’ AGRIMONIA MOLLIS BICKNELLII n. var. 
Agrimonia mollis (Torr. & Gray) Britton var., Bicknell, Bull. 
Torr. Club, 23: 517. 1896. 
Collected in the neighborhood of Wolf Creek, September 2d, 
(no. 691) where it grew in similiar situations with the type, but 
was more common. Mr. Bicknell’s excellent characterization 
leaves nothing to be added, and certainly indicates that this plant 
should have a varietal name. As Mr. Bicknell points out, the de- 
velopment of tubers is stronger than in A. mollis, and the tubers 
form on shorter roots. It is rather difficult to secure specimens of 
A. mollis that show completely the tuber development, but with 
var. Bicknell’ a vigorous pull is enough to bring the plant up with 
a number of tubers attached. The two forms are much more ob- 
viously distinct in the living state than in herbaria. It does not 
seem that the existence of intergradations should be regarded as 
an obstacle to the publication of a variety, when the majority of 
the specimens are so well-marked. : 
Geum FLavum (Porter) Bicknell, Bull. Torr. Club, 23: 523. 
1897. 
A few specimens with nearly mature fruit were found in deep 
rich mountain woods along Wolf Creek, August 23, 1897 
(no. 686), growing with Agrimonia hirsuta (Muhl.) Bicknell. 
This easily recognizable and very distinct species is here reported 
for the first time from the Southern States. 
STYLOSANTHES RIPARIA N. Sp. 
A perennial herb, with few or several (sometimes 8) stems froma = 
deep, strong, woody root, which attains a maximum lengthof3dm.
