The large number of specimens of this species in the her- 

 barium of the Missouri Botanical Garden, collected through a 

 long series of years show very clearly the characters upon 

 which this species was separated from Astragalus loiiflorus, 

 Hook. 



Dr. William Trelease has recently referred to me a card from 

 Mr. B. P. Bush, of Independence, Mo., dated April 20, 1894, 

 in which the writer states that in a recent visit to Atchison 

 county, Mo., he noticed that in this species "the early flowers 

 are long-peduncled and fruitless," while "the later ones are 

 very short ped uncled and fertile.*'
