OF BOTANICAL TERMS. 



Central Cord 



division. See Cellulose, 

 Cell-wall, Cell-sap, Pro- 

 toplasm, Nucleus. (2) Any 

 cavity, as that of au anther or 

 ovary. 



gflLL-FAMILY, a group of cells 

 of common origin: used mainly 

 among the lower algae; colony. 

 See Ccenobium. 



gfiLL-FI'BRE, see Nuclear Fi- 

 bril. 



gELLIF'EROUS, bearing or pro- 

 ducing cells. 



gELL NU'CLEUS, see Nucleus. 



gELL-PLATE, the early condi- 

 tion of a cell-wall at the equa- 

 tor of a dividing nucleus, 

 formed by the fusion of a se- 

 ries of thickenings of the spin- 

 dle-fibres called by Strasburger 

 Dermatosomes. 



g£LL, PRIMORDIAL, see Pri- 

 mordial Cell. 



gflLL SAP, fluid in living cells 

 which separates from the pro- 

 toplasm as one or more vacu- 

 oles; cytenchyma. Compare 

 Vascular Sap and Deuto- 

 plasm. 



gELL-TIS'SUE, tissue composed 

 of cells as distinguished from 

 vessels. See Cellular Tis- 

 sue. 



gEL'LULAR, composed of cells; 

 pertaining to cells as distin- 

 guished from vessels; having 

 the cells large and soft; con- 

 taining cavities of any kind; 

 porous. 



gEL'LULAR BARK, see Meso- 

 phlcsum. 



gflLLULAR EN'VELOPE, see 



MESOPHL03UM 



gEL'LULAR PLANTS, those which 

 contain no fibrovascular tis- 

 sue, as fungi and algoe; thallo- 

 phytes. 



gEL'LULAR SPORE, see Com- 

 pound Spore. 



gEL'LULAR SYS'TEM, the cellu- 

 lar portion of a plant as distin- 

 guished from the fibrovascu- 

 lar. 



gEL'LULAR TlS'SUE, tissue in 

 which none of the cells are 

 modified into ducts or vessels. 

 Especially, tissue composed of 

 cells which are large and loose, 

 like the pulp of fruits; paren- 

 chyma. Compare Vascular 

 Tissue. 



gEL'LULE, a small cell. 



gELLULlF'EROUS, bearing or 

 producing little cells. 



gEL'LULOSE, primary cell-wall 

 substance; the material form- 

 ing most of the dry matter of 

 plants. It is seen nearly pure 

 in cotton-fibre and in the cell- 

 walls of most plants while 

 young. There are many mod- 

 ifications of cellulose, among 

 them Lignin in older wood and 

 Suberiu in bark. 



gEXL-WALL, a sac enclosing the 

 living contents of a cell. 



gEMENTA'TION OF HY'PHJl, 



their inseparable union by a 

 cementing substance; concres- 

 cence. (DeBary.) 



gEM'ENT-DiSK, M filler's term for 

 the glandular disk or retinacu- 

 lum of orchids. 



gENAN'THY, the suppression of 

 stamens and pistils. 



gENO'BlUM, see Cosnobium. 



gEN66ENET'IC, secondary. 



CEN'TRAL CELL, the cell of an 

 archegonium, from which the 

 oosphere originates. Compare 

 Embryo-sac. 



gflN'TRAL CORD, a cord or bun- 

 dle of elongated thin-walled 

 cells at the centre of the stems, 

 leaves, and fruit-stalks of many 

 mosses which serves for the 

 transfer of water; tissue-cord.
