Germinative Nucleus OF BOTANICAL TERMS. 



Glaucous 



GER'MINATlVE NUCLEUS, see 

 Genekative Nucleus. 



GERM - NU'CLEUS, the nucleus 

 resulting from the union of 

 the pronuclei of two gametes 

 in conjugation or fertilization. 



GERM-PORE, a pit in the coat of 

 a spore through which the 

 germ-tube issues in germina- 

 tion. 



GERM-TUBE, the first growth 

 from a spore or sclerotium 

 upon germination. 



GIBBOUS, convex, as though 

 swollen; protuberant, espe- 

 cially upon one side, or some 

 distinct part of the surface. 



GlLL§, the spore-bearing plates 

 upon the lower side of the cap 

 in mushrooms; lamellae. 



GIR'DLE, the overlapping edge 

 of one of the two valves in

GLA'BRATE, nearly glabrous. 



GLAbRES'CENT, slightly gla- 

 brous. 



GLABRiUS'CULUS, almost but not 

 quite glabrous. 



GLABROUS, smooth; free from 

 roughness or hairs— the sur- 

 face may be uneven. Com- 

 pare Scabrous and L^vis. 



GLAD'f ATE, see Ensiform. 



GLAND, any secreting apparatus. 

 A gland is generally a group 

 of cells having a peculiar form 

 and character to adapt them to 

 their special function. They 

 sometimes form wart-like pro- 

 jections upon the surface, or 

 depressions within it. The 

 hairs of many plants also serve 

 as glands (see Glandular 

 Hair). In deeply - seated 

 glands of certain kinds, as 

 those of the pine, the internal 

 cell-walls of the gland are 

 more or less absorbed to form 

 reservoirs for the secreted sub- 



stance. The term glaud is also 

 applied to certain wart-like 

 swellings which are not secre- 

 tory, as the abortive teeth at 

 the base of the leaf in the peach 

 and cherry. 



GLAN'DlFORM, gland-shaped or 

 gland-like; adenoid. 



GLAND OF THE TORUS, see 

 Lepal. 



GLANDULAR, gland-like or bear- 

 ing glands; glanduliferous. 



GLAN'DULAR DISK, see Re- 

 tinaculum. 



GLAN'DULAR HAIR, an epi- 

 dermal appendage of one or 

 more cells, the apex of which 

 is usually enlarged and contains 

 the peculiar secretion. 



GLAN'DULAR WOOD'* TlS'SUE, 

 a term formerly applied to the 

 woody tissue of Coni ferae from 

 the appearance of its circular 

 bordered pits. 



GLAN'DULA'TION, the position 

 and arrangement of the glands 

 upon a plant. 



GLANDULf F'EROUS, bearing 

 glands. 



GLAN'DULOSE, see Glandular. 



GLAn'DULOSE-SER'RATE, hav- 

 ing serratures tipped by so- 

 called glands, as the leaves of 

 Prunus glandulosa. 



GLAN§, a nut like that of the oak 

 and chestnut, and sometimes 

 extended to all large nuts. A 

 term of little use. 



GLAR'EOSE, growing in gravelly 

 places. 



GLAUCflS'CENT, slightly glau- 

 cous. 



GLAU'COUS, covered with a 

 whitish bloom, as the leaves 

 of cabbage; more accurately, 

 light bluish green; sea-green.
