182 Astragalus Parryi Gray Am. Jour. Sci. Ser 2 33 410 (1862). 

 Pods broatliy sulcate ventrally, and narrowly and deeply so dorsally, 

 much obcompressed and with dorsal suture a little produced, falcate 

 to a lialf circle often, with cross-section about reniform or obcom- 

 pressd to that of the figure co, finely longitudinally- and cross-lined, 

 \vith walls 1-2 mm. thick when fresh, densely short-hoary when young 

 and long-shaggy when old. Flowers 6-10, 1.5 cm. long, wide. Ban- 

 ner about renitorm and deeply notched, about 1 cm. long, with very 

 short claw, abruptly arcuate at end of calyx tube to nearly erect, the 

 sides much reflexed below to 3-4 mm. wide, finely and faintly purple- 

 lined with branching veins. Wings oblanceolate and much rounded, 

 about 3 mm. wide at tips, sometimes arched to nearly erect, often 

 tinged with purple, a little longer than the keel. 2-6 mm. shorter than 

 banner. Keel about 7 mm. long and 3 mm. high, abruptly arcuate to 

 e/ect and with rounded tip which is 3 mm. wide and with a purple spot 

 at the very end. Calyx tube 7-8 mm. long, 4-7 mm. wide, a little infla- 

 ted,, inclined to be a little spurred above at the end and quite oblicjue 

 but attached near the middle of the fleshy end, papery, long shaggy- 

 hairy, mostly whitish but sometimes nigrescent, with subulate teeth 

 about as long as tube and rather lax. Pedicels stout in fruit, 3-4 mm. 

 long, ascending. Bracts green and hyaline, 4-10 mm. long, triangular. 

 Peduncles shorter than the leaves, rarely 1 dm. long. Leaves 5 cm. to 

 2 dm. long, the lowest very much reduced, and with very small round, 

 and often- notcht d leaflets, the uppermost leaves with elliptical leaf- 

 lets 1-1.5 cm. long and apiculate to retu e. Petio'es rarely a third the 

 whole, tapering as w-ell as the long rachis. Leaflets rather distant, 

 10-12 pairs, nearly smooth above, long-shajgy-hairy below, but pubes- 

 cence sparse except on young parts or on plants growing in specially 

 dry places. Upper stipules triangular and about 1 cm. long, green or 

 hyaline below, the lower ones short and wide. Stems rather thick and 

 succulent, often a foot long and with slender internodes, spreading 

 from a rather much branched and woody crown. This grows among 

 rocks in rather moist canons and blooms in late May and June. Mid- 

 dle Temperate life zone. F'rom southern Wyoming on the headwaters 

 of the Platte to central Colorado and the Sangre de Christo range on 

 the .Atlantic slope only, a species of very limited extent. 



183 Astragalus Feensis Jones Cont. 8 20 (1898). Pods about 3 

 mm, wide, and high, minutely puberulent, with cross-section triangu- 

 lar-cordate, witji dorsal suture sulcate and intruded fully to the veniral 

 as a white partition. Flowers unknown. Calyx tube about 4-5 mm. 

 long, teeth shortly pubescent, triangular, much shorter than the tube. 

 Bracts minute. Pedicels very short. Peduncles slender, about 7 cm. 

 long and about as long as the leaves or more. Leaves about 5 cm. 

 long, many, with petioles fully as long as the rachis. Leaflets 7-8 

 pairs, oval, 5-7 mm. long, rounded to notched, densely appre'^sed- 

 hairy. Old leaf-petiole* persistent. Stems tufted, very short. Whole 

 plant densely appres.= ed-hairy. This was collected onlv by Fendler, 

 No. 151, on gravelly hills at Santa Fe .Vi.v Me.^ico, May 28 1847. 

 Lower Temperate life zone. 



184 Astragalus ensiformis Jones Cont. 7 658 (1895). P ods about 6 

 mm. high, and 3 mm. wide when fresh, but much laterally flattened 

 when dry, fresh walls 1 mm. thick and soft and a little sulcate on the 

 ventral but not on the dorsal side, when dry both sutures are raised 

 and thick making the reflexed pod.s appear vetch-like. Pods arched 

 to one third circle, abruptly contracted but obtsue at both ends, the 

 stout mucro at tip an extension of the ventral suture, dorsal .suture 

 produced as a thin partition and reaching almost to the ventral, fresh 

 cross-section cordate-ovate, cavity filled by the seeds. Flowers like 

 those of A. cibarius. Pedicels short. Bracts ovate, about 3 mm. long. 

 Peduncles about 1 dm. long, rather shorter than the leaves. Leaves 

 few on the short stems, about 1.5 dm. long. Leaflets 6-8 pairs, green, 

 oval to oblong, 1-1.5 cm. long, obtuse, almost contiguous, smooth
