purplish: stigma included within a deep terminal notch.

“DRABA INTEGRIFOLIA. D. cuneifolia, var. integrifolia, 
Nats. Proc. Am. Acad. xxiii, 256. It was the one or two 
least important of the many peculiarities of this plant, 
namely, the entire leaves and the glabrous pods, which Mr. 
Watson had detected when he received it as a new variety 
of D. cuneifolia. Its obvious characters as compared with 
the real D. cuneifolia are (1) a lax raceme (2 inches long and 
of 8 or 9 pods in the largest specimens), (2) turgid pods (3) 
somewhat inclined to be falcate (4) not only glabrous, but 
notably recticulate, and (5) pointed by a stigma much more 
prominent than in any other member of this particular 
group of species. 
CARDAMINE FOLIACEA. Perennial allied to C. Breweri, 
but taller and quite erect, scarcely leafy at base, but the 
stem above bearing numerous and ample very thin leaves, 
the fruiting raceme elongated and narrow: leaves commonly 
3 inches long including the petiole, the terminal leaflet 
nearly 2 inches long, oval or round-ovate, coarsely but not 
deeply lobed, the lobes very obtuse or even almost truncate 
and mucronate, the 1 or 2 lateral pairs of less than one- 
fourth the size of the terminal, otherwise similar: fruiting 
receme 4 to 10 inches long: pods suberect on slender pedi- 
cels, very narrow, slender-pointed. 
Species apparently common in the lake region of northern 
Idaho, thence eastward into Montana. Excellent Idaho 
specimens are in my herbarium from Leiberg (n. 171), 
Heller (n. 856) and J. H. Sandberg; and the species seems 
well represented in Flodman's n. 491 from the Spanish
