Endorhiza \En`do*rhi"za\, n.; pl. {Endorhiz[ae]}. [NL., fr. Gr.
   ? within + ? root.] (Bot.)
   Any monocotyledonous plant; -- so named because many
   monocotyledons have an endorhizal embryo.

   Note: Endorhiza was proposed by Richard as a substitute for
         the term endogen, and exorhiza as a substitute for the
         term exogen; but they have not been generally adopted.
