long, oblong-oval to oblong-ovate, sulcate ventrally and a little ob- 
lique, prow-like tipped, rather truncate at the somewhat narrowed or 
abruptly rounded base, round to oval-reniform in cross section, with 
stipe 2-7 mm. long but shorter than calyx. Ventral suture a mere 
sharp-edged line externally. Flowers 2.5 cm. long, white, thin. Banner 
narrowly-oval, about 1 cm. long nearly flat, arched abruptly to 80 
degrees or erect at the. end of calyx tube or teeth and with very 
broad groove. Wings linear, nearly straight, rounded, about 1-2 mm. 
wide and 3-4 mm, shorter than the banner, and nearly as much longer 
than keel, concave to keel and flaring. White spot of banner trian- 
gular and with obscure purple veins going nearly to the upper third of 
banner, Keel about 3 mm. long and high, but little surpassing calyx, 
arched to a half circle from base, the tip triangular and obtuse and a 
little darker colored. Calyx tube cylindrical, nigrescent with scattered 
and very short hairs, about 1 cm. long and 3-4 mm. high, a little flat- 
tened laterally, narrowed a little at tip and deeper cleft with a sharp 
sinus, the upper side a little convex in the middle with the base 
straight, deltoid and fleshy and attached just below the middle of the 
end, teeth narrowly triangular and about half as long as tube, Pedi- 
cels 5-8 mm. long, mostly bracteate, several times as long as the 
ovate to triangular bracts. Peduncles almost none in flower, about 
5-8 em. long in fruit, filiform, with a few ascending and racemose flow- 
ers close together near the end. Leaves 1-1.5 dm. long, narrow. Peti 
oles nearly half the whole and persisting for several years at the crown 
Leaflets thin, oval to elliptical and tending to ovate and notched, 
about 1 em. long, shortly cuneate and petiolulate. Stems prostrate in 
small tufts, many, only a few inches long, from a gtout and long fleshy 
root. Stipules inclined to be imbricated, triangular, hyaline, very 
broad below and short, not over 5 mm. long. This grows in the 
bad lands of Wyoming north of the Uintas to Sapinero Colorado around 
the edges of the Navajo Basin in the Lower Temperate life zone on 
the poorest of clay soil in little gulches mostly, and on sharp slopes 
where there is a little alkali. It blooms very early in the spring, and 
the enormous pods (the largest in the genus) which are wholly out 
of proportion to the size of the plants soon blow off and lodge in the 
surrounding tufts of grass or weeds. It is a very variable species. 
Astragalus megacarpus var. Parryi Gray Bot. Cal. 1 148 (1876). 
A. megacarpus var. prodigus Sheldon. This differs in no particular 
from the species except that the flowers are 1.5 cm. long and purple- 
tipped with banner beautifully purple-veined, wings linear-oblanceo- 
late and about 2 mm. wide and keel base straight and purple-tipped. 
Calyx tube 5-6 mm. long, rather narrowed below and teeth often only 
a third the tube and triangular. The pubescence varies from none to 
densely hoary with rough and very short and appressed hairs on the 
younger parts. Leaflets about 5 mm. long and round to oblong, 
notched to apiculate. Pods generally smaller, Theodore, Gunnison, 
Vermilion, Sevier Bridge, Cedar City, Elk Ranch on the upper Vir- 
gin Utah. Lemmon, Rusby and Toumey also collected it in northern 
Arizona around the San Francisco peaks. This grows under oak 
brush near Tropic, but in other places in draws of the barren clay, 
slopes of the Tertiary clay strata, locally abundant, but rare gen- 
erally. Rusby’s flowers are yellow when dry. 
76 Astragalus oophorus Watson Bot. King 73 (1871). A. artipes 
Gray, Phaca Rydberg. Pods obliquely oval-ovate, about 3 em. long 
and 2 cm. wide and nearly as high, papery to nearly coriaceous, either 
 flattish on the ventral suture or somewhat sulcate, the suture straight 
Or a little convex, apiculate, deltoid to triangular-tipped, either trun- 
cate or deltoid at base, drooping, cross section cordate-obovate, ven- 
tral suture raised as a thin wing 2 mm. high or varying to a sharp 
edge only, inclined to be upcurved, pod often boat-shaped and then a -
