[ 1913 Webster ]

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. [ 1913 Webster ] 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. } [ 1913 Webster ] 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. } [ 1913 Webster ]

☞ 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. [ 1913 Webster ] For definitions, see these names in the Vocabulary. [ 1913 Webster ]

n. 1. (Biol.) A plant. See Plant. [ 1913 Webster ]

2. A plant used or cultivated for food for man or domestic animals, as the cabbage, turnip, potato, bean, dandelion, etc.; also, the edible part of such a plant, as prepared for market or the table. [ 1913 Webster ]

3. A person who has permanently lost consciousness, due to damage to the brain, but remains alive; sometimes continued life requires support by machinery such as breathing tubes. Such a person is said to be in a vegetative state. [ PJC ]

☞ Vegetables and fruits are sometimes loosely distinguished by the usual need of cooking the former for the use of man, while the latter may be eaten raw; but the distinction often fails, as in the case of quinces, barberries, and other fruits, and lettuce, celery, and other vegetables. Tomatoes if cooked are vegetables, if eaten raw are fruits. [ 1913 Webster ]
