mote, 4-10 mm. long, narrowly elliptical, obtuse. Austin, Nevada. 
Astragalus atratus var. Owyheensis (Nelson). A. Owyheensis 
Nelson Bot. Gaz. 55 375 (1913). Pods papery, shaped about as in the 
type, broadly linear, acuminate, nearly straight, about 4 mm. wide, 
2 mm. high and 1.5-2 cm. long, somewhat dorsally flattened and shal- 
low-suleate below, on a slender stipe varying up to the length of calyx 
tube from very short, on a twisted capillary pedicel often 1 em. long, 
in very lax and elongated racemes on almost capillary peduncles. often 
2° Jong. Dorsal suture a mere ridge within, cross section about reni- 
form, pod pendent, a, little inflated, splitting to the middle along the 
dorsal suture and to the base of the ventral and valves twisting, about 
smooth and mottled, with sutures rather prominent but not much 
pedicels 4-6 mm. long, ascending. Banner nearly reniform, about 5 mm. 
thickened. Flowers dullgreenish-white, about 1 em. long, on capillary 
long, thick, with sides a little reflexed above, abruptly arehed to 100° 
‘at end of calyx tube, deeply notched, Wings as long as banner and 
much enlarged above but not notched or lobed to speak of, very obtuse 
and rounded and wide. Keel purple-tipped, wide, the blade about half 
as long as wings, acute but not produced. Calyx campanulate, rounded 
at base, equally inserted, about 4 mm. long, with triangular teeth about 
1 mm. Jong or a little more. Bracts minute, ovate, hardly 1 mm. long. 
Peduncles subscapiform the proper stems being only a few inches long 
and very many from a slender and rather woody root which is much 
branched at tip as are the stems. Stipules hyaline, not connate, adnate, 
small. Normal leaves about 1 dm. long, the lower ones shorter, with 
tapering rachis and 3-5 pairs of distant leaflets which appear linear 
but are folded mostly and narrowly oblong and. apiculate and about 1 
cm. long, the uppermost one not jointed to rachis, but not elongated. 
Pubescence of fine hairs fixed by the base. The tufts He flat on the 
ground and straggle along in the grass of the meadows forming loose 
mats often 3 feet in diameter in the most favorable places. First 
collected by me at Weiser, Idaho in 1900, then at Contact, Nevada in 
1901 and in Oregon at Baker City in 1902. Because of its peculiar pod 
I was. holding it to determine its true place in the genus when Nelson . 
published it in 1913. 
Astragalus atratus var. mensanus Jones Cont. 7 665 (1895). Pods 
narrowly oblong, about 2 em. long and 3 mm. high, much laterally flat- 
tened, not sulcate dorsally, abruptly apiculate. Dorsal suture only a 
little intruded. Lower leaflets elliptical, upper, linear. Darwin Mesa 
Inyo Co. California, Coville. 
139. Astragalusibapensis Jones Cont. 3 290 (1893). Atelophragma 
Rydberg. Pods about 12 mm. long and 3 mm, wide and high, round in 
cross section, abruptly apiculate, broadly linear, a trifle wider above, 
apparently with dorsal suture a little intruded, but not sulcate. Flo wers 
about as jn A. atratus, the wings rather fanshaped and about as long 
as banner and a little longer than keel which is straight along the base 
and then abruptly arched to 45°, rarely 90° and triangular acute and 
purple-tipped and about 3-4 mm. long. Calyx tube campanulate and 
equally inserted, 2 mm. long, ascending, the deltoid teeth hardly half as 
long, ashy. Slender pedicels about 3 mm. long and much longer than 
the minute ovate bract. Floral rachis not over 1 em. long, zigzag, with 
2-3 bracts. Peduncles about 3 em. long, axillary in the 3-5 upper nodes. 
Leaves 3-4 cm. long, with petiole 1-2 cm. long and not tapering. Leaf- 
lets 1-5 linear-elliptical, the lateral ones 1 em, or less long, obtuse, flat 
thin, petiolulate and jointed to rachis, the terminal one twice as long. 
and not jointed to rachis, all the upper leaves reduced to the single 
terminal leaflets which are 2-3 cm. long and. linear-aeuminate, or with 
a minute side leaflet at the base. Stems almost filiform, about a foot 
= long, simple, several from the crown of an erect and fleshy root. All | 
but the lowest internodes 2-3 cm. long. pe > (Ibapah) Utah on.
