Name:  Rumex, Latin name for sorrel. (Hickman, Ed. 892).  Latin, salicis, the willow and Latin, folium, leaf.  (Jaeger 104, 226).  Salicifolius refers to the willow-like leaves. (my comment).  Latin, dentis, a tooth and Latin, latus, the side or flank.  (Jaeger 78, 137).  Denticulatus refers to the toothed perianth lobes, which are located on the side of the flower. (my comment).

 

General:  Uncommon in the study area, found only at the upper end of Big Canyon near Jamboree Rd.  I had looked for this plant for many years, expecting to find it close to a watercourse.  Finding it in a relatively dry area was a surprise; although nearby Salix lasiolepis trees indicate a source of moisture. (my comments).     Highly variable, even within plants; intergrading complex, warrants detailed study.  Except for tubercles, very much like var. salicifolius.   R. californicus Rech.f.   Toxic in quantity to livestock; seldom eaten. Hickman, Ed. 892, 894.
