arise the slender decumbent stems much after the fashion of A. 
Nuttallianus, but more erect, only the outer stems being pros- 
trate. The flowers are like those of A. Nuttallianus and are 
about 3 lines long; banner 2 lines wide and 2% lines long above 
the bend, dirty-white and water-lined, abruptly bent to over go° 
¥% a line beyond the calyx tips, deeply and broadly sulcate to the 
tip with a sulcus % a line deep and a line wide which occupies 
all of the upper half of the banner, sides reflexed about ¥ a line 
wide opposite the end of the keel but not at all at tip, banner 
nearly square, emarginate, with just the faintest trace of a white 
spot in the center; wings obliquely-elliptical, nearly a line wide 
in the middle, the right-hand one being folded past the end of 
the keel and the left-hand one flaring much, but both touching 
each other at the tip, both concave to the keel and obscurely 
notched below the tip, fully a line longer than keel and arcuate 
upwards, white, not distinctly water-lined; keel very short, 
abruptly bent at the end into nearly % a circle, slightly darker 
at tip, very blunt; calyx campanulate, a line long, with subulate 
teeth % a line long in addition, straight, a little obliquely inserted 
at the acutish base; pedicels slender, % a line long, as long as 
the ovate bract; fruit with ventral suture in some cases, distinctly 
concave, though normally convex, 2-celled by the intrusion of 
the dorsal suture which is a line wide exclusive of the shallow 
sulcus, papery pod smooth or minutely hairy, hoary when young, 
pendent, acute at both ends, triquetrous and with concave sides; 
stipe 11% lines long; stipules large, green normally, 2 lines long, 
triangular, adnate, not connate, the lower ones often hyaline and 
imbricated; stems a little angled, not sulcate. This was in flower 
and fruit April 19, 1900, but keeps blooming for some weeks. 
ASTRAGALUS GLAREOSUS Dougl. The writer spent some time in 
the home of this species, but did not remain long enough to com- 
plete his studies on this and the allied forms; sufficient informa- 
tion was gained to nearly satisfy him that this and 4. inflexus 
are identical except that the latter is more caulescent. 
ASTRAGALUS MALACUS Gray. This species as it generally oc- 
curs is remarkably well characterized, only in its southern range
