mm. wide, the teeth about one fourth as long as tube. Peduncles 

 about 6 cm. long and twice as long as the sessile and divaricate 

 leaves which have about 10 pairs of obovate leaflets about 1 cm. long, 

 thiclv, appearing as if glaucous, smooth above and ciliate and a little 

 appressed hairy below. Stems very slender and widely spreading 

 with long internodes and from a woody root. New Idria California,

Astragalus lentiginosus var. carinatus n. var. Pods as in the 

 var. Idriensis but not often mottled, often long-acuminate. Flowers 

 white with purple-tipped keel. Banner oblong, from half as long to 

 nearly as long as keel, abruptly arched to 45 degrees at calyx tips. 

 Wings linear, straight, about 1 mm. shorter than keel. Keel con- 

 spicuous, half-spatulate, about 5 mm. long. Calyx campanulate, the 

 tube about 2 mm. long and a little longer than the rather spreading 

 teeth. Peduncles filiform 2-3 cm. long, about a half shorter than 

 the leaves. Leaves ascending, all petioled, with about 8 pairs of 

 elliptical leaflets which are about 5 mm. long, appearing as if glaucous, 

 and ciliate and slightly pubescent beneath as in the preceeding 

 variety, but thin. Stems several, equally slender and prostrate or 

 nearly so from a slender or rather thick and woody and erect root.

Astragalus lentiginosus var. diphysus (Gray) Jones Cont. 7 673 

 (1895). A. diphysus Gray. PI. Fend. 35 (1849). var. chartacsus Jones. 

 Pods ovate and with falcate and variously acuminate tip, or body 

 oval but always with the falcate beak, cross section variously reni- 

 form to didymous, often 4 cm. long. Leaves all petioled, leaflets 

 mostly obovate, rarely elliptical, 8-10 pairs, 1-2 cm. long, mostly 

 smooth. Peduncles shorter than the leaves which are often 1 dm. 

 long. Internodes short. Stems many in tufts, erect to ascending, a 

 foot or two high. Flowers about 2 cm. long, purple, with elongated 

 banner, the oblanceolate wings rather longer than keel. Common in 

 the sagebrush from Santa Fe New Mexico and Holbrook Arizona to 

 Wyoming, southern Idaho and the Sierras. This intergrades freely 

 into the forms with papery pods. A. cuspidocarpus Sheldon which is 

 A. ammolotus Greene, as to Leiberg's material at least is a form of 

 this. Middle and Lower Temperate life zones. A form of this from 

 Lima Montana intergrades with the type species. A. lentiginosus var. 

 chartaceus Jones is a form intergrading with the var. latus below. 



Astragalus lentiginosus var. latus. (A. diphysus var. latus Jones 

 Cont. 3 287 (1893). A. latus Jones Cont. 5 272 1894) also. This Is 

 a densely csespitose form with woody stems from a stout root and 

 herbaceous tips a few inches long and flat on the ground. The pods 

 are almost globose and conical pointed, varying to oval with rather 

 falcate tip. about 2 cm. long, didymous, often mottled, hidden among 

 the leaves on peduncles rarely over 2 cm. long. Flowers light- 

 purple, about 2 cm. long, very narrow, the banner and wings elon- 

 gated. The tubular tui)e is about 8 mm. long and 3 mm. wide, and 

 the teeth triangular to filiform and often half as long as tube. 

 Leaves about 1 dm. long, all petioled, with about 6-8 pairs of oval to 

 obovate leaflets, a little over 1 cm. long and smooth. A remarkable 

 variety but nothing else. Rocky canons in the mountains free 

 from alkali. Middle Temperate life zone. Rather common in east- 

 ern Nevada. Type locality Aurum. A form of this with tiny flowers 

 and globose and apiculate pods rather papery is from Monatchy Mead- 

 ows California Purpus, No. 1971, and is ashy pubescent. 



Astragalus lentiginosus var. palans Jones Cont. 4 37 (1893) and 

 Cont. 8 4 (1898). Pods linear and falcate often to a half circle, 3-4 

 cm. long and hardly 5 mm. wide, with cross section inclined to be 

 triquetrous, sharply acuminte, cross-wrinkled. Flowers purple and 

 about 2 cm. long with elongated banner and wings and cylindrical
