 long, appressed silky-pubescent, acute or obtuse : peduncles equalling 

 or exceeding the leaves (2 or 3 inches long) ; racemes short, loose ; 

 flowers ascending : calyx tubular, 4 lines long, with short slender teeth ; 

 corolla purplish, twice longer : pod coriaceous, ovate with a rounded 

 base, more or less depressed when mature and somewhat sulcata on the 

 ventral side, 1 -celled, sessile, G to 9 lines long and 4 to G broad, silky- 

 pubescent. — Near Williams' Station, Arizona, by Mr. and Mrs. J. G. 

 Lemmon, July, 1884. Of the Scylocarpl group ; the shape of the pod 

 nearly that of our native chestnut, though it is somewhat smaller. 



Astragalus tkoglodytus. Biennial or perennial (?), the root- 

 stock bearing several crowded stems an inch long or less : leaves 

 long-petioled, 4 inches long ; leaflets G to 8 pairs, oblong-obovate, 

 4 or o lines long, acute or obtuse, strigose-pubesceut : scape-like 

 peduncles much exceeding the leaves (G to 8 inches long) ; racemes 

 short, dense ; bracts jiersistcnt (2 or 3 lines long) and reflexed : 

 flowers small ; calyx campanulate, 2 lines long, the slender teeth 

 half the length of the tube ; corolla twice longer : pod subglobose, 

 coriaceous, sessile, 1-celled, scarcely exceeding the calyx (2 or 3 lines 

 long), silky-pubescent, 2-6-seeded. — In the San Francisco Moun- 

 tains, Arizona, near " Cliff-dwellers' Ravine," Mr. and Mrs. J. G. 

 Lemmon, August, 1884. A species of the Scytocarpi group, strongly 

 marked by its scapose habit in connection with its small flowers and 

 very peculiar pod. 



Astragalus fallax. Perennial, with slender decumbent flexu- 

 ous stems a foot long or more, canescently pubescent : leaves sessile, 

 short; leaflets about 8 pairs, oblong to obovate, 2 to 6 lines long, 

 obtuse or retuse : peduncles much exceeding the leaves ; raceme loose ; 

 flowers reflexed : calyx campanulace, 2^- to 3 lines long, with very 

 short teeth ; corolla purplish, half an inch long : pod very shortly stipi- 

 tate, subcoriaceous, oblong-ovate, turgid, somewhat depressed and sul- 

 cate when mature, acute at each end, 1-celled without intrusion of the 

 sutures, 8 to 11 lines long including the stipe, and 3 or 4 lines broad, 

 spreading or deflexed. — In Western New Mexico, collected by Wright 

 (n. 1004) and l)y Sitgreaves, and at Flagstaff near the San Francisco 

 Mountains, Arizona, by Rushy, and also by Lemmon. It has long been 

 confused with A. Feiidhri^ and Wright's specimens were made the 

 basis of the revised description of that species in PI. Wright. 2. 24, 

 which has been maiidy followed in later works. The real A. Fend- 

 LERi, collected by Fendler, Parry, and Rothrock, in New IMexico aiul 

 Colorado, has less pubescence, narrower leaflets, somewhat smaller
