| dove plant | <botany> A Central American orchid (Peristeria elata), having a flower stem five or six feet high, with numerous globose white fragrant flowers. The column in the center of the flower resembles a dove. Synonym: Holy Spirit plant. Source: Websters Dictionary (01 Mar 1998) |

| dove | 1. <zoology> A pigeon of the genus Columba and various related genera. The species are numerous. The domestic dove, including the varieties called fantails, tumblers, carrier pigeons, etc, was derived from the rock pigeon (Columba livia) of Europe and Asia; the turtledove of Europe, celebrated for its sweet, plaintive note, is C. Turtur or Turtur vulgaris; the ringdove, the largest of European species, is C. Palumbus; the Carolina dove, or Mourning dove, is Zenaidura macroura; the sea dove is the little auk (Mergulus alle or Alle alle). See Turtledove, Ground dove, and Rock pigeon. The dove is a symbol of innocence, gentleness, and affection; also, in art and in the Scriptures, the typical symbol of the Holy Ghost. 2. A word of endearment for one regarded as pure and gentle. "O my dove, . . . Let me hear thy voice." (Cant. Ii. <zoology> 14) Dove tick, a mite (Argas reflexus) which infests doves and other birds. Soiled dove, a prostitute. Origin: OE. Dove, duve, douve, AS. Dfe; akin to OS. Dba, D. Duif, OHG. Tba, G. Taube, Icel. Dfa, Sw. Dufva, Dan. Due, Goth. Db; perh. From the root of E. Dive. Source: Websters Dictionary (01 Mar 1998) |
| dove's-foot | <botany> A small annual species of Geranium, native in England; so called from the shape of the leaf. (04 Mar 1998) |
| air plant | <botany> A plant deriving its sustenance from the air alone; an aerophyte. The "Florida moss" (Tillandsia), many tropical orchids, and most mosses and lichens are air plants. Those which are lodged upon trees, but not parasitic on them, are epiphytes. Source: Websters Dictionary (01 Mar 1998) |
| aquatic plant | <botany> Plants that must grow in water whether rooted in the mud or floating without anchorage, plants that must complete part or all of their life cycle in or near the water. (09 Oct 1997) |
| C3 plant | <plant biology> Plants that fix carbon dioxide in photosynthesis by the Calvin Benson cycle. The enzyme responsible for carbon dioxide fixation is RuDP carboxylase, whose products are compounds containing three carbon atoms. C3 plants are typical of temperate climates. Photorespiration in these plants is high. (07 Nov 1997) |
| C4 plant | <plant biology> Plants found principally in hot climates whose initial fixation of carbon dioxide in photosynthesis is by the HSK pathway. The enzyme responsible is PEP carboxylase, whose products contain four carbon atoms. Subsequently the carbon dioxide is released and re fixed by the Calvin Benson cycle. The presence of the HSK pathway permits efficient photosynthesis at high light intensities and low carbon dioxide concentrations. most species of this type have little or no photorespiration.
