Note 92 — {289} APPENDIX C

In these villages, where the grass is fed close, and where much fresh earth is brought up and exposed to the air, is the peculiar habitat of a species of Solanum approaching the S. triflorum of Nuttall, which, he says, occurs as a weed "about the gardens of the Mandans and Minatarees of the Missouri, and in no other situations." It appears to differ from the S. triflorum in being a little hirsute, with flat, runcinate, pinnatifid leaves, and the peduncles alternating with the leaves. The Solanum heterandrum of Pursh, now referred to the new genus Androcera of Nuttall, is also very common, but is not confined, like the plant just mentioned, to the marmot villages. We collected also the Psoralea cuspidata, Ph. P. esculenta, N. P. incana, N. also a species of Hieracium—H. runcinatum. Plant hirsute, leaves all radical, elliptic-oblong, runcinate; scape few-flowered, somewhat compressed, and angular; glands on the hairs of the calix, very small and diaphanous; about one foot high; flower small. Hab. in depressed, grassy situations along the Platte.
