intruded; seeds large, fully a line long and nearly round, on a 
stalk a line long, few, confined to the middle of the pod; calyx 
one and one-half lines long, campanulate, scarcely oblique at 
narrowed base; subulate teeth one-half shorter. The cross 
section of the pod is probably round. 
Specimens collected by Mr. Lemmon in Sierra County have 
long underground stems and short ascending stalks, four inches 
- high, decumbent; pods thicker, one-half as large, more attenuate, 
with the stipe only equaling the calyx; leaves ovate to elliptical, 
acute, with prominent midnerve and very hairy. This would 
seem to connect with 4. Whztneyi. The pods of both these 
species are one-celled. The flowers are not found in these 
specimens, but are said to be white in the former and purple in 
A. Whitneyt. 
Astragalus proriferus n. sp. San Pedro Martir, Lower Califor- 
nia, May 5, 1893, Brandegee. Allied to 4d. Hornit. Shrubby at 
base, one to two feet high, stems ascending, whole plant hoary with 
very short woolly pubescence which is denser above; the flowers 
only are glabrous, not the calyx; leaves four inches long, 
_with a petiole an inch or less long; leaflets about ten pairs, 
oblong-lanceolate and obtuse but apiculate, to obovate and 
obtuse and not apiculate, three to ten lines long and one to three 
wide, acute at base; stipules triangular, herbaceous, acute, two 
to three lines long, upper ones little reduced; peduncles stout, 
one-half as thick as stem, six inches long, erect, many flowered 
from below the middle, racemose in fruit and spicate in flower; 
flowers dark purple, but keel lighter, fading to ochroleucous; 
calyx broadly campanulate, tube a line long, oblique, cleft 
deeper above; pedicels almost obsolete shorter than the obscure 
ovate bract, teeth as long as the tube, subulate, erect; keel three 
lines long, bent abruptly to a right angle or more at tip, acute, 
arched a trifle; wings lanceolate and apparently notched at 
tip; banner rather large, nearly round, ascending 80° abruptly 
from a point beyond the calyx teeth, a line longer than 
wings and keel, emarginate; pods obliquely ovate to oval, six 
lines long, three to four wide, chartaceous, inflated, one-celled, 
neither suture in the least inflexed, dorsal suture not evident, 
ventral suture much thickened in the middle where only, it is
