seed-bearing in the middle and seed stalks long, pods 6" 

 long by 3" wide, papery; flowers nearly white, but purple 

 tipped, apparently. 



Astragalus serotinus Gray, Pac. R. R. Rep. 12, 18 

 and 51, i860, var. campestris (Nutt. T. & G. Fl, i, 

 351. 1838. 



Astragalus campestris Gray, P. A., A. 6, 229. 



Astragalus convallarius Greene. 



No. 6032b. September 11, head of the Sevier River, 

 Utah, 8000° alt., in gravel, under Pinus -ponder osa. 



No. 6oi5n. September 7, Panguitch Lake, Utah, in 

 volcanic gravel, under Pinus ponderosa. 



No. 5958q. August 29, Brigham Peak, Utah, 11,700° 

 alt., on open slopes, at and above timber line, in gravel. 



No. 6oo2n. September 6, Panguitch Lake, Utah, in 

 gravel, 8400° alt., under pines. 



No. 5695h. July 27, Mt. Ellen, Henry Mountains, 

 Utah, 10,500° alt., on open slopes, above timber line and 

 below it, in volcanic soil; never seems to grow in any but 

 well drained soil. 



It is manifest, from an abundance of material from 

 many localities, that this is only a variety of A. serotinus, 

 since the calyx teeth and keel of the flower vary much, 

 and show all sorts of intergrades. 



As has been indicated above. Astragalus strigosus 

 Coulter and Fisher, with its synonym, A. griseopubens 

 Sheldon, is the same as A. serotinus. 



Astragalus Hookerianus (T. & G.) Gray, var. 

 Whitneyi (Gray P. A. A. 6, 526). An examination of 

 a large amount of material from the California Academy 

 of Sciences shows that this is only a variety of A. Hook- 

 erianus, as the characters do not hold. 



Astragalus Virgineus Sheldon, Death Valley Rep., 

 seems to be the same as A. sahulonum Gray.
