URTICA CARDIOPHYLLA 11. sp.
Urtica dioica (?) Rydberg, Contr. Nat. Herb. 3 : 179. 1895.
Stem about I in. high, angled and striate and, as well as the leaves, nearly devoid of bristles ; leaves broadly cordate, or the upper somewhat narrower, 6—Ici 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-lanceolate, 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 author near Whitman, Neb., in 1893. In the report it was doubtfully re (erred 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.
