leaflets 5 to 7 pairs, linear, obtuse, narrowed at base, about | inch 

 long : spikes rather slender, pedunculate, 2 inches long or less ; bracts 

 very narrow and attenuate, deciduous, equalling the calyx : calyx cam- 

 panulate, somewhat scarious below, thicker and glandular above, with 

 short triangular acute teeth pubescent on the inner side ; petals rose- 

 color fading to nearly white, twice longer than the calyx : pod gla- 

 brous. — Collected by J. Reverchon in Bandera County, Texas, at the

Petalostemon Reverchoni. Perennial, with numerous slender 

 ascending stems 6 inches high or less, finely pubescent : leaves glabrous 

 or the petiole slightly pubescent ; leaflets 2 to 5 pairs, linear, acutish, 

 subrevolute, 2 to 5 lines long : spikes sessile or nearly so, very short 

 or becoming 2 inches long : calyx covered with line appressed pubes- 

 cence, the acuminate teeth nearly equalling the tube ; petals deep 

 pink or red, a half longer: pod silky-pubescent. — On the rocky 

 top of Comanche Peak, in western Texas ; J. Reverchon, June, 1882

Astragalus Pringlei. Near ^. Cobrensis ; annual, procumbent, 

 much branched from the base (stems 6 inches long or less), canescent 

 with very fine appressed pubescence : leaves 1 or 2 inches long ; leaflets 

 5 to 7 pairs, linear to oblanceolate, obtuse, 1 to 3 lines long, finely silky- 

 pubescent both sides or glabrous above : racemes numerous, short- 

 pedunculate, about equalling the leaves, loosely few-flowered : calyx 

 tubular, 2 lines long, with short narrow teeth ; petals pink, 5 lines 

 long, the narrow keel erect : pod 2-celled, chartaceous, oblong, straight, 

 sessile, deeply and at length broadly sulcate on the back, the ventral 

 suture not prominent, 3 to 5 lines long, ascending, pubescent. — Plains 

 near Chihuahua; C. G. Pringle, April, 1885 (n. 79). 



Astragalus misellus. Of the Galegiformes group, perennial, 

 with numerous ascending herbaceous stems (6 inches high), canescent 

 throughout with short appressed pubescence : leaves (an inch or two 

 long) with 8 to 10 pairs of small linear-oblong leaflets : peduncles 

 about equalling the leaves, few-flowered : flowers spreading or reflexed: 

 calyx campanulate, the narrow teeth nearly equalling the tube ; petals 

 yellowish, twice longer (3 or 4 lines) : pod linear, somewhat curved, 

 attenuate to a stipe a little longer than the calyx, compressed, 2-celIed 

 and Y-shaped in section, rather narrowly sulcate on the back, acute 

 on the ventral edge, reflexed, finely pubescent, 8 to 10 lines long. — 

 Near A. Howelli, but a much smaller and smaller-flowered species,
