Catalogue of the Flora of Nebraska. 35 
linear-filiform, revolute; bracts ovate, densely villous, as is also 
the calyx, with grayish, slightly tawny hairs (Rydberg). 
327. P. sp. P. candidus var. occidentalis Gr. of Pringle’s col- 
lection, according to Dr. Britton. It is, however, clearly no 
variety of P. cundidus, but may be of P. gracilis, Nutt., of the 
south, to which it is nearly related. It differs from P. gracilis in 
having more oblong leaves, longer more lax spikes, and glandular 
dotted calyx. Dr. Britton says if distinct from P. gracilis it is 
clearly a distinct species (Rydberg). 
200. PSORALEA L. Psoralea. 
328. P. pigirata Nutt. Aurora (Williams). Much confounded with 
P. campestris. Specimens in the Herb. of Univ. of Nebr. collected 
at Anselmo by Webber and at Valentine by Rev. Bates, evidently 
belong here. Nebraska specimens collected by Dr. Bessey, have 
been referred to P. digitata by Dr. Britton (Rydberg). 
32¥. P. FLORIBUNDA Nutt. This species, I think, should not be merged 
into P. tenuiflora Pursh. It is either a distinct species or a well 
marked variety. P. floribunda Nutt. found in eastern Nebraska 
has generally 5 oblong leaflets, 1-1} in. long; many flowered ra- 
cemes; lower calyx teeth longer; and larger flowers. P. tenuiflora 
Parsh, of western Nebraska, has 3 oblong-oblanceolate leaflets, 
4-3 in. long; few flowered racemes; and punctate, colored calyx 
with equal teeth. Dr. Britton, to whom specimens and my notes 
upon them have heen sent says: ‘‘ I had concluded that P. flori- 
bunda could not go unnoticed into P. tenutflora.”? The matter 
needs more investigation. Most of the localities for P. tenuiflora 
in the catalogue of Nebr. Flora belong to P. floribunda. The only 
specimens of the true P. tenuiflora I have seen are those collected 
by Dr. Bessey, at Ft. Robinson, and my own, from the plains of 
Deuel Co., Aug. 1890 (Rydberg). 
330. P. HyPoGa#A Nutt. Alliance, Lewellen (Swezey). Hills, Deuel 
Co., June 26 (Rydberg). 
331, P. piInwaRIFOLIA Torr. & Gr. Magnesia cliffs in Deuel Co., July. 
Racemes very loose, 3-6 in. long; leaflets 3, linear, 1-2 in. long; 
stem, leaves, and calyx glandular dotted (Rydberg).

332. T. procumBeNs L. Low hop-clover. Yards aud roadsides, 
Lincoln. Adventive from Europe (Webber). 
202. LUPINUS L. Lupine.

rare. War Bonnet, June (Williams).

Hat Creek Basin, common (Webber).
