Webber —Catalogue of the Flora of Nebraska. 35 
linear-filiform, revolute; bracts ovate, densely “toa as is also 
the calyx, with grayish, sien 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. eondidus, 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 isin longer more lax spikes, and glandular 
' dotted ealyx. Dr. Britton says if distinct from P. gracilis it is 
clearly a distinct species (Rydber, rg). 
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). 
32y. 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, 1-14 in. long; many flowered ra- 
cemes; lower calyx teeth longer; and larger flowers. P. tenuiflora 
Parsh, of western Nebraska, has 3 oblong-obianceolate leaflets, 
3-4 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. tenuiflora.”? The matter 
needs more investigation. Most ofthe 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).

Racemes very loose, 3—-Gin. long; leaflets 3, linear, 1-2 in. long 
stem, leaves, and calyx glandular dotted (Rydberg).
