and having gathered very many specimens of all forms, I 

 am certain that this is identical specifically with A. erio- 

 carfus Watson, and must therefore take the name. Un- 

 fortunately Watson's type is an abnormal form of his 

 species, having grown in the shade, and therefore having 

 abnormally long peduncles, but having collected it abun- 

 dantly near his typical localities, and finding both long 

 and short peduncles, according to the exposure, I have 

 no hesitation in placing it here as a variet}^ 6f A. New-

 var. exigitus Sheldon.

Astragalus Seatoni n. sp. Near to Hartzvegi, but 

 with slender stems. Collected by H. E. Seaton, on Mt. 

 Orizaba, Mexico, 10,000" alt., August 6, 1891. Also by 

 Bourgeau, at Cacubaya, near Mexico City, 1866. The 

 latter plant is stouter, strigose and with fewer leaflets; 

 pods papery; root thick. Seaton's plants have very 

 slender ascending or spreading stems; leaflets linear or 

 nearly so, 6-8" long, 10-12 pairs; peduncles long and 

 slender, 4-8' long; spikes linear, loose, 1-2' long; bracts 

 scarcely visible; calyx almost globular, the tube about 

 ^" long and teeth one-third as long, triangular and black- 

 hairy; flowers yellowish or white, sessile ; banner round, 

 not over i" long or less, sides reflexed, a little longer than 

 the narrow-oblong wings, which are arcuate, and about 

 one-fourth longer than the semicircular oblique keel; 

 pods oblong-oval, 2" long, i" wide, and cross-section 

 nearly round, deeply sulcate and septum produced, but 

 pods not wholly 2-celled, apiculate, very short stipitate, 

 apparently jointed to the stipe; pods and flowers reflexed
