(Bot. Herald, 28), collected by him at Cape Lisburne, on the Ameri- 

 can side, in flower only. Captain Pullen's plant, collected west of 

 Cape Bathurst, seemed to be the true 0. arctica, R. Br.

11. O. visciDA, Nutt. in Torr. & Gray, Fl. i. 341. Floribus in 

 capitulum oblongum demumve spicam tripollicarem congestis ; calyce 

 brevi-campanulato pilis albidis vel griseis villoso; legumine parvulo 

 (lin. 3-5 longo) tantura puberulo stylo recto tenui-rostrato. — Rocky 

 Mountains, from the British Possessions to Colorado and N. Nevada; 

 common in Wyoming. The small projecting glands which give the 

 viscidity are sometimes conspicuous on petioles, scapes, bracts, and 

 calyx, and even on the legume, but in many dried specimens they are 

 hardly to be detected. Flowers about 5 lines long : corolla probably 

 not ochroleucous, sometimes apparently white with either the tip of 

 the keel or lamina of wings and standard violet. The species is well 

 represented by no. 89 of Parry's N. W. Wyoming collection ; also by 

 his no. 88, in flower only, and by no. 292 of Watson's collection m 

 King's Exploration. Northward it was collected by Bourgeau (dis- 

 trib. as 0. campestns?), and by Macouu, at Bow River Pass. 



12. O. LEUCANTHA, Pers. Syn. ii. 331 ; Bunge, Oxytr. 111. 0. 

 horecdls, & 0. leucantha, DC. Capitulo etiam fructifero brevi parum 

 oblongo; calyce oblongo-campanulato pilis nigris albidisque villoso; 

 legumine ventricoso |-pollicari nigricanti-villoso stylo mox recurvato 

 rostrato. — Specimens of this from C. Wright's collection on Arakamt- 

 schetchene Island, on the Asiatic side of Behring Strait, have been so 

 named by Bunge, and they accord with the figure of Astragalus leiican- 

 thus in Pall. Astrag. t. 47. Not a good name, th^ corollas being, as 

 in the figure, well suffused with violet. Stouter forms of it were col- 

 lected by Seemann on the American side, perhaps white-flowered; and 

 a form with white-haired calyx was collected at Cape Thompson, &c. 

 by Muir. A part of 0. campestris of Hook. Fl. Bor.-Am. must also be 

 of this species. Although placed among the glandular-viscid species 

 by Bunge, the glandulosity is obscure, and in some specimens not 

 apparent. Occasionally the long hairs of the calyx seem to be viscous.
