 I have determined Fendl. no. 149 to be
 A. missouriensis, Nutt. (A melanocarpus. Hook.!)


 But now I want to know about 148.
 It might be A shortianus, but the flowers are
 deep blue. I should like much to see a spce. of
 Nuttalls A. [?]. to make all sure.


 Now for your 3 Expl. Exped. specimens.
 [?]. 1014. = A. lentiginonis. [?] of which fortunately
 I have a Hookerian legume only. Hooker
 knew not the flowers, which now you can supply.


 [?]. 543. is a new species, I doubt not. It is not
 in my herb. nor can I make it agree with any description
 It is also abundant in Spaldings coll. & is
 what I suppose Carey has reported to you as "Oxytropis
 diflexa [?] sencea?"
 It is well distinguished by its setaceous calyx-
 teeth, nearly as long as the corolla nearly & the woolly, lentil
 like 2-celled legume.-


 " 543 (a) is not difft. I suspect, though the raceme elongates
 in front & the legume is diflexed. I think the Spalding
 specimens  this, not in [fruit?] will unit them. But you will
