  Endogen \En"do*gen\, n. [Endo- + -gen: cf. F. endog[`e]ne.]
     (Bot.)
     A plant which increases in size by internal growth and
     elongation at the summit, having the wood in the form of
     bundles or threads, irregularly distributed throughout the
     whole diameter, not forming annual layers, and with no


     distinct pith. The leaves of the endogens have, usually,
     parallel veins, their flowers are mostly in three, or some
     multiple of three, parts, and their embryos have but a single
     cotyledon, with the first leaves alternate. The endogens
     constitute one of the great primary classes of plants, and
     included all palms, true lilies, grasses, rushes, orchids,
     the banana, pineapple, etc. See {Exogen}.
