Ocreati. 242 
slightly 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 
oblanceolate, 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 em. 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 pods. Stems densely tufted from a long and 
erect tap root. On the Moencoppa in the Little Colorado 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. '

(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-lanceolate-acuminate, about 1 cm. long. Calyx 
about 4 mm. long, with teeth about half as long. Flowers about 1 
em. 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.
