         applied in Spain to several kinds of mint ({Mentha
         sativa}, {viridis}, etc.), but in California
         universally applied to a common, sweet-scented labiate
         plant ({Micromeria Douglasii}).

   {Yerba dol osa}. [Sp., herb of the she-bear.] A kind of
      buckthorn ({Rhamnus Californica}).

   {Yerba mansa}. [Sp., a mild herb, soft herb.] A plant
      ({Anemopsis Californica}) with a pungent, aromatic
      rootstock, used medicinally by the Mexicans and the
      Indians.

   {Yerba reuma}. [Cf. Sp. reuma rheum, rheumatism.] A low
      California undershrub ({Frankenia grandifolia}).
