to 4 lines long; peduncles 3 to 8 inches long, with racemose, scat- 
tered flowers on the upper half; flowers very small, erect to hori- 
zontal; calyx nigrescent, less than a line long; campanulate, triangu- 
lar teeth a line long; calyx acute at base, on a pedicel Y% a line 
long, subtended by a triangular bract 1 line long; corolla arched; 
the very blunt, much incurved, and rounded, purple-tipped keel 
surpassing the calyx tips less than a line; wings oblong, entire, 
about a line longer than keel, ascending, flat to keel; banner ab- 
ruptly bent at calyx tips to a right angle, 2 lines longer than keel, 
broad, deeply notched, white or light pink; pods ascending to pen- 
dulous, linear-oblong, dorsal suture straight, ventral slightly 
curved, minutely stipitate, flat and vetch-like, abruptly acute or 
apiculate, membranous, reticulated, with no trace of a dorsal intrud- 
ing septum; seeds (6 to 10) broadly ovate to almost reniform. 
Were it not for the characters of the pod this might be referred to 
A. Robbinsii, var. occidentalis, Watson. May 7, 1891, at Thomp- 
‘son’s Springs, Eastern Utah, on rocky slopes, rare. Named for 
Col. D. C. Dodge. 
ASTRAGALUS IBAPENSIS, n. sp. Allied to A. Robbinsti, var. occt- 
dentalis apparently, but leaves seemingly quite different, and pod 
also. (?) The description of Watson’s variety is very meager and 
gives almost no leaf or floral characters. This plant is very slender; 
stems ascending from a deep, erect and slender perennial root; leaf- 
lets 1 to 7, elliptical to linear, lower obtuse, the upper acute, all but 
the terminal ones 2 to 6 lines long, the terminal one twice as long 
as the others; upper leaves with one long, linear leaflet, acute at 
each end, 1 to 134 inches long, r line wide, gradually tapering into 
the rachis or petiole, which is 6 lines long and not jointed to it, oc- 
casionally with a single falcate, very acute, linear leaflet at base; 
stipules ovate to broadly triangular and mostly connate, usually 
acute; very slender stems grooved; whole plant minutely strigose 
pubescent, even to the pods, which are more densely so and not 
black hairy; penduncles slender, racemosely arranged on stems, 1 to 
2 inches long; flowers white, 1 to 3, at*the top of peduncle; 
spreading pedicels a line long and with an ovate bract at base, ap- 
parent reflexed in fruit; calyx shortly campanulate, a line long and 
as broad; teeth triangular, 1% line long; corolla 3 lines longer than 
calyx and teeth; banner very broad, abruptly arched at tip of teeth
