ampliata, lobis rotundatis subsequalibus ; antheris (§ Saccan- 

 therce) rima hispido-ciliatis juxta insertionem villosulis ; filamento 

 sterili glaberrimo apice dilatato. — A depauperate specimen of 

 this is what, in the account of Lieut. Beckwith's collection, 

 (Pacific Railroad Explorations, 2, p. 122,) I doubtfully referred 

 to P. heterophyllus. It proves to be a very distinct species of 

 the same section, and a handsome one, the (apparently bright 

 blue) corolla over an inch in length.
