Astragalus crassicarpus Nutt. Iraser’s Cat. (1818). 
From the characters of the fruit given in Fraser’s Catalogue, this can be identified 
with Astragalus caryocarpus Ker;! which will therefore come under Nuttall’s name, 
Not common in the region. Collected in fruit only: Norway, June 22 (No, 1419). 
Astragalus lotiflorus Hook. Fl. Bor. Amer. i, 152 (1834), 
Rare: only a few specimens co.lected in fruit near the Forks of Dismal River, July 
13 (No. 1547). 
Astragalus ceramicus longifolius (Pursh) nom. nov.; Psoralea longifolia Pursh, 
Fl. ii, 741 (1814). 
The name longifolius could not be used as aspecific name under Astragalus as there 
is already an 4. longifolius,? but it may well be adopted as a varietal name under 
Astragalus ceramicus.* Common in the sand hills: Thedford, June 16and 17; Norway, 
June 22 (No, 1322), 
Spiesia lambertii (Pursh) Kuntze, Rev. Gen. Pl. i, 207 (1891); Oxytropis lambertit 
Pursh, Il. ii, 740 (1814). 
On the sand hills near Thedford, June 17; Norway, June 17 (No, 1285). 
Glycyrrhiza lepidota Pursh, I'l. ii, 480 (1814). 
In meadows: Thedford, June 20; Mullen, July 20 (No. 1384), 
Meibomia canadensis (L.) Kuntze, Rev. Gen. i, 195 (1891); Hedysarum canadense 
L. Sp. Pl. ii, 748 (1753), 
Miss Anna M. Vail, in a Torrey Bulletin,‘ gives it as a character of MW. canadensis 
that the leaves are not reticulated below. In the form growing in the open mead- 
and comparatively lax; bracts mostly ovate, abruptly acuminate, a little longer, or 
sometimes shorter, than the calyx, deciduous, generally fallen at anthesis. 
This has been a puzzling form for a long time. Dr. Gray called it Petalostemon 
gracilis in Plante Fendlerianw remarking as follows: ‘‘Some of the specimens, I 
know not from which locality, have awn-pointed or cuspidate bracts, which are 
longer than the flower buds and are scarcely, if at all, distinguishable from P. candi- 
dus, to which the whole species is perhaps too closely related.” Dr. Torrey in the 
Botany of the Mexican Boundary Survey, calls it P. candidus, adding the following 
note: ‘Our plant resembles Fendler’s specimens named J. gracilis by Dr. Gray, but 
is erect.” Later, it was named in manuscript by Dr. Gray, Petalostemon candidus 
occidentalis. As it is found in several herbaria under this name, I adopt the 
last part as a varietal name. I thought [had found characters which would dis- 
tinguish the plant specifically from A. candida, viz, the more abrupt acumination of 
the bracts, and the less persistency of these and the bristles of the rachis, characters 
fairly constant in Nebraska specimens; but Mr..J. N. Rose, Assistant Botanist of the 
United States Department of Agriculture, who has also examined the plant, has 
shown methat these characters are not reliable. It is, I think, more nearly related to 
K. multiflora; in fact, can scarcely be distinguished from it except by the length and 
arrangement of the spikes. This is especially the case with my specimens from 
the Black Hills, in which the bracts are generally shorter than the calyx. As no 
definite line can be drawn between the present variety and A. candida on the one 
hand and A. multiflora on the other, I think it best to include all as varieties under 
one species. Perhaps A. gracilis should also be included therein. The Texas 
specimens in the National Herbarium, labeled Pefalostemon gracilis belong to K. 
candida occidentalis. The Florida specimens are somewhat different and may be 
distinct.
