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 ^ a line 

 long, subtended by a triangular bract i 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, 1 891, at Thomp- 

 son's Springs, Eastern Utah, on rocky slopes, rare. Named for 

 Col. D. C. Dodge. 



Astragalus Ibapensis, n. sp. Allied to A. Robbinsii, var. occi- 

 dentalis apparently, but leaves seemingly quite d fferent, 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 I to 7, ellipticil to linear, lower obtuse, the upper acute, all but 

 the terminal ones 2 to 6 lines long, the terminal one tyv^ice as long 

 as the others; upper leaves with one long, linear leaflet, acute at 

 each end, i to i}^ inches long, i 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, i to 

 2 inches long; flowers white, i 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, 5^ line long; corolla 3 lines longer than 

 calyx and teeth; banner very broad, abruptly arched at tip of teeth
