close to calyx, jointed to a minute stipe at base, ascending or reflexed. 

 both sutures evident and nearly alike, the ventral intruded 1 mm. deep 

 or less; seed talks as long as the obliq.iely reniform seeds which are 

 nearly 2 mm. long and brown. Flowers racemose, 10-15. Banner l-!: 

 mm. longer than keel, nearly round, notched, with sides reflexed below, 

 arched in an abrupt curve from calyx tips to nearly erect. Wings nearlj 

 linear, arched and exposing keel, a little longer than keel, oblique. 

 Keel ascending, about reaching to calyx tips, abruptly bent at tip to 

 90 degrees and acutish. Calyx tube faintly onerved, ashy campanu- 

 late, not gibbous, 3 mm. long and as long as the subulate teeth or a 

 little longer. Bracts ovate, acute. Pedicels erect in flower and reflexed 

 variably to horizontal or more in fruit, 4 mm. long, usually twice 

 the bracts, stout. Peduncles angled, stout in fruit, erect, including 

 floral rachis 12-15 cm. long and floriferous on the upper third. Leaves 

 5-10 cm. long, nearly sessile. Leaflets 6-9 pairs, linear-oblong, barely 

 obtuse at tip and base or notched above, all on the upper side of the 

 rachis, about 1 cm apart. Internodes about 2-3 cm. long, the lowest 

 ones 5-10 cm. long. Stems rather coarse, 2 feet high, tufted, decum- 

 bent, angled. Plants very minutely puberulent, the young pods, pedi- 

 cels and peduncles hoary at first. From the Organ Mts. New Mexico 

 to the Colorado through the Mogollons. Lower Temperate life zone. 

 Growing on gravelly and dry benches or along dry watercourses. This 

 Is hard to separate from robust forms of A. triflorus except by the 

 larger purple flowers and evidently perennial roots from a rather 

 woody base. Plants distributed by E. O. Wooton from Mesilla Val- 

 ley April 20 1905 as A. Wootoni Sheldon are this species, also No. 34 

 Metcalf from near Silver City New Mexico distributed as A. playanus. 

 It is quite possible that Sheldon's type was mixed with A. subcinereus. 



64. Astragalus Wetherilli Jones Cont. Cont 4. 34 (1893). Phaca 

 Rydberg. Pods ascending, shortly acuminate, half-oval-ovate, about 

 2-2.5 cm. long and 1 cm. wide and high, very slightly flattened laterally 

 and cross section nearly round but flat along the ventral suture, not 

 silicate, chartaceous, rounded at base and jointed to the tip of a 

 slender stipe nearly as long as calyx, sometimes reddish but not mot- 

 tled. Flowers about 1 cm. long, narrow, white or only purple tinged, al- 

 most in heads, ascending. Banner about 6 mm. long, oblong, abruptly 

 arched remote from calyx tips to 45 degrees, 2 mm. longer than winss, 

 with sides reflexed about 1 mm. wide. Wings nearly linear, arched to 

 nearly 45 degrees, obtuse, a little longer than keel. Keel with straight 

 and narrow base about 1 mm. wide, the tip sharply rounded to a 

 bo If circle and very obtuse, 2 mm. high, purple at tip. Calyx narrowly 

 campanulate, the tube about 3 mm. long, acute at base and attached 

 on lower corner, the subulate teeth nearlv as ling as tube, nigrescent. 

 Pedicels stout, nigrescent, 2-3 mm. long, about as long as the triangular 

 IjrHcts. Peluncles slander. 2-4 cm. lonsr erect, fruiting rachis 1-2 

 cm. long and rarely with more than 3 pods and half a dozen flowers. 

 Leaves 4-5 cm. long, slender and thin, nil petioled, the lower petioles 

 more than hnlf the who'e. the tii^npr nenrlv hnlf. T ower leaflets neirly 

 round and shortly-cuneate at the long-petiolulate base, upper leaflets 

 broadly elliptical, about 1 cm. long, flat and thin, rounded, 4-5 pairs 

 or the upper 6-8 pairs, almost smooth. Stems slender, in dense tufts 

 rf !i!noh hiTincbed woody base, ascerdine. flpxuous. about 2 ft. high. 

 Stipules small, not connate. Peduncles in most of the axils. Along 

 the Grand River near Grand Junction Colorado, and to Moab, Utah, 

 Miss Eastwood. Lower Temperate life zone. 



65. Astragalus jejunus Watson Bot. King 73 (1871). Phaca Ryd- 

 berg. Pods nearly smooth, mottled when in the sun, flattish to a tri- 

 fb s:)lc't. venfrtillv, faintlv triquetrous when fresh, a little later- 

 ally flattened, merely apiculate, apparently jointed to a minute boss
