“ URTICA CARDIOPHYLLA N. sp. 
Citica dioica (?) Rydberg, Contr. Nat. Herb. 3: 179. 1895. 
Stem about I m. high, angled and striate and, as well as the 
leaves, nearly devoid of bristles; leaves broadly cordate, or the 
upper somewhat narrower, 6-10 cm. long, coarsely toothed, very 
thin, dark green, perfectly glabrous and shining; petioles about 
3 cm. long, very slender; flower clusters small, rather few-flowered, 
in the specimens seen scarcely more than half as long as the peti- 
oles; stipules linear-ianceolate, 5~10 mm. long, very thin. 
On a wooded creek bank, near Castle, Montana, Aug. 1, 1896, 
J. H. Flodman, no. 370.. A specimen was collected by the au- 
thor near Whitman, Neb., in 1893. In the report it was doubt- 
fully referred to U. dioica (Rydberg, no. 1790). It is evidently 
near U. gracilis, from which it differs in the broader thinner leaves, 
the smaller flower-clusters and the nearly complete absence of 
bristles. 
CORIOSPERMUM VILLOSUM N. sp. 
Stem 2-4 dm. high, much branched from near the base, the 
branches divergent, striate, when young with the leaves and 
bracts villous with many branched hairs, in age glabrate; leaves 
linear, 2-4 cm. long, 1-3 mm. wide, cuspidate-mucronate; spikes 
rather dense, with more or less imbricated bracts; lower bracts 
linear-lanceolate, 5-10 cm. long, the upper ovate-acuminate and 
cuspidate, 4-5 mm. long and about 3 mm. wide with broad 
Scarious margin ; achene 2~2%4 mm. long and 2 mm. wide, acutely 
margined but scarcely at all winged. 
The following specimens belong to this species: Montana: 
P. A. Rydberg, no. 2623, 1895, from Manhattan, in flower. 
Colorado: Isabel Mulford, from Salida, in fruit. S. Watson, no. 
993, from Carson Desert, Nevada, 1867, seems also to belong here. © 
There are at least three species of Coriospermum in the United 
States, viz.: 
C. hyssopifolum L. with a low branching stem, more or less — 
pubescent when young, very dense spikes with imbricated bracts, — - 
which are all broadly ovate, generally over 5 mm. long, and large 
achenes about 314-5 mm. long and with broad wing margins. It 
grows around the Great Lakes and northward to the Arctic and 
westward to Washington. : Le 
C. nitidum Kit (C. hyssopifolium microcarpum Wats.), with tall — 
slender perfectly glabrous stem, ascending branches, lax spikes,
