and crisped but not woolly. Flowers narrow as in the type, blue-black 
when dry, about 3 cm. long, with the calyx a half longer than the blades 
and rather shaggy and with the soft hairs more spreading and inclined 
to be nigrescent er black, the subulate teeth often 6 mm. long, the flow- 
ers (about 5) are darker and with much deeper red than the pink-pur- 
ple of A. Utahensis but resemble it very much but bloom nearly ‘a 
month earlier and at the same time as A. Purshii which is very early. 
Bracts often half aslong as the calyx. Peduncles and leaves about 
1-1,5 dm. long. Petioles about twice as long as the leaf-rachis. Leaf- 
lets about 5 pairs, nearly oval, acutish at both ends, 1-1.5 cm long, 
greener but stillvery pubescent. Crowns oblong, several, 3-7 cm. long. 
uy the side of these in the open and without shade grow forms with 
all kinds of variations but with leaves and peduncles short or pedun- 
cles and petioles almost none and with leaflets reduced in number and 
size. Common throughout the Great Basin from the base of the Wa- 
satch to the Sierras and southward to Owen’s Valley and the southern 
flanks of the Mogollons of Arizona, growing on dry benches and on 
slopes in the sagebrush and junipers, Lower Temperate life zone, nev- 
er in alkaline soil nor on poorly drained flats. This is nearest to A. 
Utahensis but does not grow with it and is found at a lower elevation. 
It and A. Purshii grow together and they hybridize freely. It is easily 
separable from it by the coarse pedicels, straightish pubescence, large 
flowers, narrow keel and much wider pods. The hybrids are easily 
recognized and do not seem to persist. This blooms about 10 days be- 
fore A. Purshii, beginning early in May at 6000 ít. alt. and proportion- 
ally earlier at lower elevations. 
Astragalus Newberryi var. castoreus Jones Cont. 7 658 (1895). 
This is a form with leaves and peduncles about 5 cm. long, 3 pairs of 
leaflets about 6 mm. long, elongated petioles, nigrescent calyx, purple 
tipped flowers about 2.5 cm. long with keel tip nearly erect and 4 mm. 
high and much less rounded. Pods elongated-lanceolate, about 3 cm. 
long and abruptly bent (about one third the way up) toan erect flat- 
tish and elongated tip twice as long as:the base. Calyx teeth triangu- 
lar and about 2-3 mm. long. This grows at the copper mine 18 miles. 
west of St. George Utah, a very rare form, No. 5006. eee 
Astragalus Newberryi X Eurekensis. Thisis avery rare hybrid 
with diamond-shaped leaflets 1-2.5 cm. long, 2-3 pairs, minutely and 
rather sparsely pubescent with closely appressed hairs, slender pedun- 
cles and petioles not conspicuously persistent, the former shorter than 
the leaves which are 5-8 mm. long. Pods more sparingly hairy and 
obliquely-oblong-lanceolate and about 2 cm. long. Calyx nigrescent. 
Flowers purple-tipped. Lake Point Utah, No 1743, May 29 1880. An- 
other collection much like it is from Richfield and has more oblong 
leaves and obliquely-oval and sparsely hairy pods about the shape of 
A. argophyllus. One would expect to find many specimens of this 
hybrid, but they are very rare. 
. 175 Astragalus Eurekensis Jones Cont. 3 291 (1893) and 8 12 (1898) 
Pods acuminate-lanceolate, 2-4 cm. long. about 8 mm. wide and 5 mm. 
high, arcuate in the middle to over a half-circle generally, notched at 
base, sulcate ventrally and dorsally at base and toward the middle till 
the ventral suture touches the dorsal making the cross-section of pods 
linear, above the podsare laterally compressed toward the rather 
long and triangular tip, with pubescence loosely shaggy-silky with 
rather long hairs which do not conceal the brown surface of the 
strongly reticulated pods which are reddish till fully ripe. sutures 
raised as strong ribs, pods with base horizontal to ascending, a little 
narrowed below, mostly single to few at the ends of the slender pe- 
duncles which are decumbent and shorter than the leaves. Flowers 
cream-white with purple-tipped keel, appearing lurid-white when dry, 
about 2.5 cm. long, narrow, erect, 3-8. Banner elliptical to ovate and 
about 1 cm. long, strongly notched, gently arched beyond the calyxto — —
