Scapes glabrous or nearly so, i'-6' high, little if at all elongating in fruit. Leaves 3-7, the blades ovate to elliptic, obtuse, 4'-ii' long, the margins usually inrolled; calyx \\"-2\" long, the lobes ob- tuse, the 2 lower ones more or less united; corolla violet-purple, Y'-io" long including the subulate acute spur, 2-lipped, the lips equally spreading, the upper 2-lobed, the lower 3-lobed; capsule ovoid, 3"-4" long, 2i"-3" in diameter. On wet rocks or gravelly places, circumpolar; south- ward in America to Newfoundland, New Brunswick, Vermont, northern New York, Michigan, Minnesota, Montana, and British Columbia. June-July. Bean- weed. Yorkshire sanicle. Sheep-root or-rot. Rot-grass. Sheepweed. Steep or earning-grass, from its use in curdling milk. Pinguicula alpina L., reported from Labrador on account of a single specimen said to have been col- lected there many decades ago, probably does not occur in North America. It has flowers about the size of those of P. vulgaris, but nearly white and with a very much shorter obtuse spur. 2. VESICULINA Raf. Fl. Tellur. 4: 109. 1838. Aquatic herbs, with horizontal submerged stems, the branches verticillate, and verticil- lately or oppositely decompound. Leaves, at least in the adult plant, none. Bladders terminal on the ultimate branches, the mouth naked or with a single median hairy proboscis. In- florescence racemose, 1-4-flowered; scales on the lower portion of the scape none; pedicels from the axils of bracts, without bractlets, erect in fruit.
