Most of the Sierran material differs from Bigelow's type in the 

 greater amount of the pubescence, which is somewhat scabrid, also in 

 the foliage being slightly succulent; these differences Dr. Greene con- 

 sidered sufficiently marked to separate Heleniastruni rivulare (Fl. 

 Fran., p. 435. 1897), but Dr. H. M. Hall has pointed out^- the 

 inconstant nature of these characters.
