green at least at tip, blunt, or rarely acute, often 6" long, 

 and resembling the bracts; pedicels about 3^" long. 

 Throughout the Great Plateau, in subalpine meadows, Or 

 even as low as 6000° alt., in meadows. Apparently from 

 Bolivia, Rusby, but specimens more like those of Europe. 

 Astragalus virgiiltidus Sheldon is the same as A. agrestis 

 apparently. 



Astragalus hypoglottis L. as figured in Pall. Astrag. 

 has subulate pointed bracts ; campanulate calyx, teeth 

 subulate and shorter than the short tube; banner short 

 and oval; wings oblong and barely longer than the keel; 

 leaflets lanceolate and always acute ; stipules much smaller, 

 bracts ovate to linear-lanceolate ; calyx lobes less than 

 half the tube; pods with longer stipe and broader, ovate, 

 very blunt at both ends; plants sparsely hairy with long 

 slender hairs (ours are usually nearly glabrous) ; pods 

 simply hairy; leaflets about 8 pairs; peduncles longer 

 than the leaves. 



Astragalus Canadensis L. var. Carolinianus (L). 



This seems to be a very good geographical variety, 

 abounding from North Carolina to the Ohio River, and 

 rarely bej^ond. This has long open spikes of small, not 

 greenish nor thick flowers ; oblong-oval, apiculate, 2-celled 

 pods, 4" long. 



Astragalus siniflicifolius (Nutt. T. & G., Fl. i, 350, 

 1838) Gray. It is manifest that this is a reduced form of 

 what has heretofore been called Astragahts ccBspitosus. 



Astragalus simplicifolius var. c^spitosus (Nutt. 

 T. &G.,F1. 1,352). 



To this must be referred the very common and normal 

 form of the species.. The synonymy is A. ccBspitosus 

 (Nutt.) Gray, P. A. A. 6, 230; Tragacantha ccespttosa 

 OK. Rev. Gen. PL 2, 943; Homalobus canescens Nutt.
