to make it peculiar among its supposed allies. The specimens, 

 though in full petaliferous flower, are nevertheless rather too 

 young. 



Three New Astragali. 



Astragalus subuniflorus. Near A. Nuttallianus, the root 

 annual, stem slender, erect, simple, or branched only above 

 the base if at all, mostly 2 to 6 inches high, cauescent with an 

 appressed coarsely silky pubescence, but upper face of leaflets 

 sometimes almost glabrous, these in about 4 pairs, not 

 crowded but rather remote on their rachis, in outline elliptic- 

 oblong : peduncles filiform, nearly erect, usually 1-flowered, 

 some of the later 2-flowered : calyx with short tube and much 

 longer narrowly lanceolate-subulate teeth : pod somewhat 

 shorter than in A. Nuttallianus, more acute, glabrous. 



Near Tehuacan, Puebla, Mexico, 7 Aug. 1897, C. G. 

 Pringle, n. 6678 as in my set of that collector's plants. 



Astragalus pertenuis. Also near A. Nuttallianus and 

 annual, branched from the base and these branches often 

 more than a foot long, prostrate, slender, flagelliform, spar- 

 ingly leafy, the whole plant, even to the pods, clothed sparsely 

 with appressed straight hairs : leaflets in 3 to 5 pairs, remote 

 on the elongated rachis, extremely diverse in form on each 

 plant, those of the earliest leaves only a line long, cuneate- 

 obcordate, those next them 3 lines long, oblong-cuneiform to 

 oblong-linear and from truncate to acutish, uppermost foliage 

 with linear acute or acuminate leaflets Vo, inch long or more : 

 peduncles filiform, shorter than the leaves, often 1-flowered, 

 none more than 2-flowered : pods small, 3 to 5 lines long, 

 appressed-setulose . 



A Lower Californian species, known to me in flowering 

 specimens from Los Angeles Bay, and in fruiting ones from 

 Cedros Island, all collected years ago by Edward Palmer.
