 P. virgatum, Scheele in Linnaa, 21. |). 461. PrairieS, Austin, Texas. — From the 

 Snake Conntry, in the interior of Oregon, Mr. Burke sent to Sir Wm. Hooker dwarf 

 specimens of this variety, and from the Black Hills of the Platte both Burke and 

 Gordon have sent others, with densely pubescent leaves and even tomentose stems, 

 which I cannot otherwise distinguish from this species. Some specimens, having 

 long acuminate bracts, approach too near io P. decumbens, which is further distin- 

 guished chiefly by its broader leaflets.
