First Report on the Flora of Wyoming. 95 



Dalea aurea, Nutt. Fras. Cat. (18 13). Parosela aiirea, (Nutt.) Britton. 



Very rare; on the plains of the Platte; Fairbanks, July 11, 1894 

 (No. 390). 

 Petalostemon candidus, Michx. Fl, Bor. Am. ii, 49 (1803). KuJniis- 

 tera c and hi a, (Willd.) Kuntze. 



Occasional, on the dry hills and plains bordering on the Platte. 

 Orin Junction, August 14, 1891, B.C. Buffum. 

 Petalostemon multiflorus, Nutt. Journ. Phil. Acad, vii, 92 (1834). 



This seems to be a much-named plant and illustrates nicely the 

 stability that our nomenclature is acquiring. The new Check List 

 gives Kuhnistera niultijiora, (Nutt.) Heller, and, if I understand Mr. 

 Rydberg rightly, his new name, Kuhnistera, Candida 7nultiflora, 

 (Nutt.), Contrib. Nat'l Herb, iii, 3. (1895), is also the same. From 

 the specimens at hand J am inclined to think that Mr. Rydberg is 

 right in reducing the form to a variety. On the other hand his 

 variety occidetitalis does not seem to differ in any important respect 

 from his miiltiflora, judging by his descriptions. Some specimens 

 at hand will fall nicely under either. 



Very frequent in the Laramie Hills and the foothills bordering on 

 the Platte. July 9, 1894 (No. 330); Inyan Kara Divide by B. C. 

 Buffum. 



Petalostemon violaceus, Michx. Fl. Bor. Am. ii, 50 (1803). Kuhn- 

 istera purpurea, (Vent.) MacM. 



Habitat and localities much the same as for the preceding. 

 Orin Junction, July 14, 1891, B. C. Buffum; Platte Hills, July 9, 

 1894 (No. 331). 

 Astragalus adsurgens, Pall. Astrag. 40, t, 31 (1800). A. Laxnmnni, 

 Jacq. 



Remarkably abundant in the south-eastern part of the state, 

 occupying dry, stony or gravelly ridges on the plains or in the foot- 

 hills. 



Wallace Creek, July 29, 1894 (No. 646); Cummins, July 30, 1895 

 (No. I 5 14); at Laramie at various times. 

 Astragalus alpinus, L Sp. PI. 760 (1753). 



Probably frequent in the higher mountain valleys; Pole Creek, 

 June 3, 1894 (No. 174); Union Pass, August 11, 1894 (No. 840). 

 Unusually large specimens with leaves varying from eUiptical to 

 obcordate were obtained on Union Peak, August 13, 1894 (No. 993).
