broadly ovate and acutish, a little longer than the pedicels but not 
equaling the calyx. Calyx obconic, rather oblique at tip and base, a 
little over 2 mm, long, with the triangular black teeth about a third 
the whole, Banner purple-speckled, about 2-3 mm. long, abruptly 
arched at calyx tips to nearly erect, about oval but with sides reflexed 
from base to tip and seeming oblong. Wings a trifle shorter than 
banner and arched 45 degrees, broadly oblanceolate, obtuse, not ex- 
posing keel, white or tinged with purple and a little speckled, keel 
about 2 mm shorter than banner (blade) and gently arched to near 
the tip and then sharply arched in all to about 200 degrees, then 
the very broadly deltoid tip erect, purple. Pods hoary, ovate and 
with cross section rather rounded, about 4 mm. long or less, about 
l-seeded. Apparently not sulcate nor conspicuously oblique. This 
has the habit of A. montanus and has doubtless been mistaken for it, 
Blooms April to May. Gathered by Brandegee on the Mesa Verde 
Colorado. Apparently common at the Grand Canon of the Colorado 
at the end of the railroad on sandy ledges. The floral characters 
are taken from the Grand Canon material, This can at once be 
separated from montanus by the leaflets jointed to the rachis 
20. Astragalus Gilensis Greene Tor. Bull. 8 97 (1881). Leaflets 
about 8 pairs, shortly acute, 5-7 mm. long, with the appearance much 
that of A. humistratus and with hairs not fixed at the ends. Leaves 
inclined, to spread out on the ground, 5-8 cm. long, rarely more. 
Prduncles many, scapose, inclined to be decumbent, 10-12 cm. long. 
Flowers capitate, about 16, purple, about 7 mm. long. Calyx tube 
about 3 mm. long campanulate, narrowed below, the subulate teeth 
nearly as long. Bracts acuminate-lanceolate, ascending, hyaline, about 
3 mm. long. Banner nearly round, 2-3 mm. long, abruptly arched to 
erect at calyx tips, with sides much reflexed and rather deepiy 
notehed. Wings broadly linear, rounded, arched to 45 degrees and 
exposing keel base, about 2 mm. shorter than banner and as much 
longer than keel. Keel almost exactly that of A. humillimus but tip 
a trifle more acute, about 2 mm long. 1 mm. shorter than wings, 
2 mm longer than calyx. Pods about 5 mm long, and a half longer 
than the calyx, half-oval, the dorsal suture straight and the ventral 
much arched and very thick, not inflated, laterally flattened and cross- 
section elliptical, sharply and very abruptly apiculate, rigid and hoary 
with close hairs, both sutures thick and prominent. This has many 
short branches from the crown and conspicuous stipules overlapping 
so as to form a narrow cone like mass 1-3 cm. wide, the edges some- 
what ciliate but otherwise hyaline and smooth. This has the general 
appearance and habit of A. calycosus, but the flowers and pods are 
of the Sericoleuci. This grows in dry places along the canon of the 
Gila in New Mexico and Arizona, Lower Temperate life zone. Also 
£athered by Parry No. 264 Mex. Bound. Survey at Santa Cruz Pass. 
Also in the Mogollons Socorro Co New Mex Metcalfe. 
21. Astragalus sericoleucus Gray Am. Journ. Sci. Ser. 2 33 410 
(1862). Phaca sericea and trifoliata Nutt. Orophaca serieca (Nutt.) 
Britton. Tragacantha sericea (Nutt) Kuntze. Pods hoary, about 6 
mm. long, oblong-ovate, flattened a little J^terally but not arched, half 
included in calyx, a trifle inflated. Flowers normaliy purple, near- - 
ly sessile, rarely 1 cm. long, few at the ends of a short peduncle- 
which is rarely as long as the leaves or even shorter than the sti- 
y” les. Banner oval to obovate, notched, 4-8 mm. long, abruptly arched 
at end of calyx to erect or more, with evident white-spot and pu le- 
veined. Wings lanceolate, often oblique, about as wide as keel at base - 
and 2-3 mm. longer and about as much shorter than banner. Keel 
not surpassing calyx teeth, with base about straight and erect part —— 
as tong and arched sharply to at east 90 degrees, obtuse and puse ;
