Northwestern Sonora, March, 1884, collected by Mr. 

 Pringle, and distributed nnder the name D. cimeifolia, var. 

 hrevijjes, Watson; but the minute, emarginate petals, branches 

 racemose throughout their whole length, and pods on not 

 only shorter but ascending or sub-erect pedicels, mark it as 

 distinct from D. cimeifolia.
