﻿Astragalus lentiginosis var. diaphanus (Dough 

 Hook. Fl. i, 151). This precedes lentiginosis on the 

 page, but I follow the usual rule of keeping up the long 

 used name. This variety includes all papery pods which 

 are linear, compressed and falcate, and may include A. 

 palans Jones with its variety araneosus (Sheldon, 1. c. 9, 

 170), though A. palans seldom has papery pods.

This includes the prostrate forms with oval pods.

This is a v 

 var. difkysus, 



ariety of the type approaching lentiginosu. 

 and appears to be the same as A . araneosu. 



Sheldon, the type of which is in my collection. 



Astragalus amphioxys Gray has tor a synonym A.cres- 

 ceniicarpus Sheldon, being exactly typical; also A. ves- 

 pertinus Sheldon, 1. c. 9, 150, in which the pod is 

 obcompressed. The flattening either into compressed or 

 obcompressed is purely accidental in this species, and 

 varies with the development and bending of the pod. 



All the forms of Astragalus amphioxys are at once dis- 

 tinguishable from any forms of A. Shortianus by the 

 pubescence, which is in the latter species fixed by the 

 base, while in the former it is fixed near the middle, and 

 therefore giving the plants a silvery appearance. 



Astragalus Newberryi Gray. Having now gone over 

 again and again the ground where this species was found.
