Astragalus streptopus Greene, Bull. Cal. Acad. i, 1¥6. 
This I take to be a form of 4. Nuttallanus. ‘The only differ- 
ence seems to be that the flowers are a little more numerous and 
racemose and the leaflets are often retuse. I have specimens 
with racemose flowers, and others with the pods wrong side up 
by the twisting of the pedicels, and otherwise intermediate. 
Astragalus albens Greene, seems to be a good species but 
very close to A. Nuttallianus, though Watson places it near 4. 
tricarinatus. It would pass fora form of 4A. Nuttallianus with - 
wider leaves and tips of pods. If this is a perennial it blooms 
the first year. It is prostrate or ascending, six inches or more 
long, many branched from the base; raceme loose; peduncles 
twice as long as the leaves, which are one to two inches long, 
petiole over one-half of the whole; keel purple tipped, very 
broad and blunt, longer than the wings and equaling the broad 
banner, two lines longer than the calyx and teeth, which are a 
line long, teeth equaling the campanulate tube, pedicel nearly 
as long as the tube; pod broadly linear, narrowed and pseudo- 
stipitate at the base, broadest at apex, which is sharp-pointed 
and triangular, laterally compressed, minutely and ~ rather 
sparsely short-pubescent, not at all silky except when very 
young, two-celled. Described from the type. 
Astragalus Rusbyi Greene, is a good species. I also collected 
it in abundant material near Flagstaff, Ariz., 1884 
Astragalus malacus Gray, var. Laynee (Greene). A. Laynee 
Greene, Bull. Cal. Acad. i, 157, belongs to the Micranthi. In 
addition to the characters given I find the flowers are purple, one- 
half an inch long; wings narrow, just surpassing the keel, and 
banner but little longer; banner ascending; keel apparently with 
an obtuse short beak; leaves almost oval, very villous-woolly, the 
hairs very fine, not much tangled in the type but much so in 
Parish’s specimens, attached by the small pustulate base, the 
leaflets in the Mrs. Curran specimens are obovate; the flowers seem 
to be reflexed and the pods erect; calyx campanulate, nigrescent, 
three lines long, with very short, triangular, black-hairy teeth; 
peduncles very stout, twice longer than the four-inch-long leaves, 
or subscapiform, and eight inches long in Mrs. Curran’s speci- 
i]
