Sanguinaria Canadensis, L. (A celebrated medicine plant.)

CAPPARIDEÆ

Peritoma serrulatum, De C. (Cleome serrulata, Pursh.)

VIOLARIACEÆ

Viola Canadensis, Pursh—V. pubescens, Nutt.—V. sagittata, Ait.—V. villosa, Ell.—V. cucullata, Ell.

POLYGALEÆ

Polygala alba, Nutt. Torrey in Ann. Lyc. Novebor II. p. 168. The root is quite the same as that of the officinal Radix senegæ.

LINEÆ

Linum rigidum, Pursh? Agrees indeed, in many particulars, but the petals are not narrow (angustissima), but obovate, longer than the calyx; the lower leaves of the stalk are opposite, very small, and linear-spatulate, 1-1½ lines long. The sepals are beautifully ciliated, with glandular teeth.
