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,
