‖n.; pl. Endorhizæ [ NL., fr. Gr. &unr_; within + &unr_; root. ] (Bot.) Any monocotyledonous plant; -- so named because many monocotyledons have an endorhizal embryo. [ 1913 Webster ]

☞ 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.

{ } a. (Bot.) Having the radicle of the embryo sheathed by the cotyledon, through which the embryo bursts in germination, as in many monocotyledonous plants. [ 1913 Webster ]
