 Vegetable kingdom Nat. Hist., that primary division of living things which includes all plants. The classes of the vegetable kingdom have been grouped differently by various botanists. The following is one of the best of the many arrangements of the principal subdivisions.
 I. Phaenogamia (called also Phanerogamia). Plants having distinct flowers and true seeds. { 1. Dicotyledons (called also Exogens). -- Seeds with two or more cotyledons.  Stems with the pith, woody fiber, and bark concentrically arranged.  Divided into two subclasses: Angiosperms, having the woody fiber interspersed with dotted or annular ducts, and the seeds contained in a true ovary; Gymnosperms, having few or no ducts in the woody fiber, and the seeds naked.  2. Monocotyledons (called also Endogens). -- Seeds with single cotyledon. Stems with slender bundles of woody fiber not concentrically arranged, and with no true bark.}
 II. Cryptogamia. Plants without true flowers, and reproduced by minute spores of various kinds, or by simple cell division. { 1. Acrogens. -- Plants usually with distinct stems and leaves, existing in two alternate conditions, one of which is nonsexual and sporophoric, the other sexual and oophoric.  Divided into Vascular Acrogens, or Pteridophyta, having the sporophoric plant conspicuous and consisting partly of vascular tissue, as in Ferns, Lycopods, and Equiseta, and Cellular Acrogens, or Bryophyta, having the sexual plant most conspicuous, but destitute of vascular tissue, as in Mosses and Scale Mosses. 2. Thallogens. -- Plants without distinct stem and leaves, consisting of a simple or branched mass of cellular tissue, or reduced to a single cell.  Reproduction effected variously. Divided into Algae, which contain chlorophyll or its equivalent, and which live upon air and water, and Fungi, which contain no chlorophyll, and live on organic matter. (Lichens are now believed to be fungi parasitic on included algae.}
 Note: ☞ Many botanists divide the Phaenogamia primarily into Gymnosperms and Angiosperms, and the latter into Dicotyledons and Monocotyledons. Others consider Pteridophyta and Bryophyta to be separate classes. Thallogens are variously divided by different writers, and the places for diatoms, slime molds, and stoneworts are altogether uncertain.
    For definitions, see these names in the Vocabulary.

It is wrought into various articles, as buttons, chessmen, etc. The palm is found in New Grenada. A smaller kind is the fruit of the Phytephas microarpa. The nuts are known in commerce as Corosso nuts.
