Ocreati. 242 



sliR-htly so ventrally. Flowers spreading, deep-bluish-purple-tipped, 

 about 7 mm. long and 2-5 mm. long, longer than the calyx and 

 teeth. Banner broadly ovate, veined, with sides reflexed much 

 and arched at the end of calyx tube to 45% 5-7 mm. long, with 

 short claws, 2 mm. longer than keel. Keel straight, broad, trun- 

 cate, with tip erect. Wings 2 mm. shorter than banner, broadly 

 oblanceolatc, little arched, narrower than keel, rounded, oblique. 

 Calyx tube 3 mm. long, shaggy above with tangled and very fine 

 hairs, the subulate teeth a little shorter than the tube. Bracts 

 2-5 mm. long, hyaline, ovate to lanceolate. Peduncles (as well as 

 stems and leaf rachis) filiform and rush-like, often a foot long, 

 tapering, racemose on the upper half. Leaves often 3 dm. long, 

 mostly 7-9 cm. long. Petioles generally grooved, green, a quarter 

 to as long as the leaf. Leaflets nearly smooth, broadly linear to 

 almost filiform, about 2.5 cm. long, the upper ones reduced or abor- 

 tive, about 5 pairs, acute, all distant, somewhat narrowed below. 

 Lower stipules broadly triangular, short, hoary above. Internodes 

 very slender, 1-3, the upper 5 cm. long. Whole plant nearly smooth 

 except the calyx and po(]s. Stems densely tufted from a long and 

 erect tap root. On the Moencoppa in the Little Coloi-ado region of 

 northern Arizona in the Navajo Basin and in the San Rafael Swell 

 south of Green River, Utah, in sandy places. Lower Temperate life 

 zone. 



204. Astragalus troglodytes Watson Proc. Am. Acad. 20 362 

 (1885). Leaflets 6-8 pairs, oval to obovate and obtuse or rarely 

 acute, about 1 cm. long, with closely appressed hairs fixed by the 

 base. Leaves erect, about 1 dm. long, with petiole*inclined to be 

 longer than its rachis. Stems almost none. Peduncles ascending 

 to erect, about 1.5 dm. long. Flowers spicate, rather many. Bracts 

 recurved, linear-lanceolatc-acuminate, i bout 1 cm. long. Calyx 

 about 4 mm. long, with teeth about half as long. Flowers about 1 

 cm. long. Pods loosely hairy, 5-7 mm. long, conspicuously obcom- 

 pressed, and cross-section oblately oblong, with the thick sutures of 

 Gilensis and its abrupt apiculation, the suture only slightly arched 

 at tip and base, not sulcate, cavity inflated. The pods have about 

 the shape of Matthewsii on a minute scale, only a little exceed- 

 ing the calyx, but it has no relation to the Scytocarpi. It is mani- 

 festly a close ally to the Sericoleuci, Gilensis section. Coconino in 

 the San Francisco Mts., Arizona. Lower Temperate life zone.
