the embryo or germ sac, a cell containing the germ (Figs. 109 e m 

 E ; 178 S, E). The integuments do not entirely cover the nucellus, 

 but at one place a narrow passage is left between them. This is 

 called the micropyle * ; and through this the pollen tube passes in 

 fertilisation, after it has come down the stigma, until it reaches the 

 embryo sac and fertilises the germ, or oosphere^ as it is called. 

 (cf. Fig. 178). 



FIG. 178. Ovule shortly after fertilisation, k nucellus, with S, 

 embryo sac ; E, embryo which has begun to grow from the fertilised 

 oosphere ; a, outer, z, inner integument ; f t funicle ; n, micropyle ; 

 p, pollen tube. 



Gland. A cell containing or separating from the sap, some oily or 

 other special substance, cf. glandular hairs, p. 82, 81 Fig. 54. 



GynoilS. Used in composition with other words, and refers to the 

 pistil. It is from the Greek " gune" gen. gunaikos, a woman,

 from the Greek "gunaikos" as above, and " oikion," a house: 

 the woman's 'house, 

 (ii.) Used sometimes (as androus is) of the 'pistil carpels, ovaries, 



styles, or stigmas. Digyndus, etc., see Androus ii. 

 . (iii.) So also protogynous or proterogynous, when the pistil matures 

 before the stamens, cf. Androus iii.
