(from seeds gathered by Col. Fremont) for several years in the Botanic Garden, Cam-

gulatim exserentibus. Styli filiformes introrsum stigmatosi (hirtelli). Ovulum in loculis solitarium, peritropo- 
adscendens. Capsula depressa, polycocca; carpella rotundato-reniformia vel cochleata, omnigo mutica, 
semini conformia, indehiscentia, ab axi centrali secedentia. Semen reniforme, loculum implens. Embryo 
arcuatus vel semicircularis: radicula infera. — Herbe gerontogew ; floribus purpureis, roseis, seu albis. 
M. rotunpiro.iA, Linn., is extensively naturalized in North America. 
M. soreatts, Wallm. (vide supra No. 75), has doubtless been brought from the Old World also. 
M. malachroides, Hook. & Arn. Bot. Beech. Suppl., from California, of which the fruit is unknown, is 
probably of a different genus.

Involucellum nullum, vel 1 -3-phyllum persistens. Petala cuneiformia, truncata, apice szepe eroso-denti-

This species in its inflorescence and in the minuteness of the hollow beak, which is incurved as the fruit 
ripens so as to escape notice, makes the nearest approach to Malva; but the structure is really the same with 
that which is displayed on a larger scale in the following section. A carpel is figured in Genera Amer. Bor.-
