  • Discussion

    This species is related to H. stenophyllus but the stem and leaves are strigose-canescent. It has been mistaken for H. Anliselli but the leaflets are much narrower and pubescent on both sides. Besides the type, the following specimens belong here.

    Southern California: Kenworthy, II. M. Hall 1182;

    San Bernadino Mountains, Parish Brothers 1281. Lower California: Orcutt, in 1885; 856, in 1883.

  • Distribution
