Endorhiza

Endorhiza , noun

[New Latin, from Greek {not transcribed} within + {not transcribed} root.]

(Botany) Any monocotyledonous plant; -- so named because many monocotyledons have an endorhizal embryo.

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.
