Fruit, six weeks after fertilisation. 



Seed with plug of endosperm, as shown in Fig. 11. 



Fruit, eight weeks after fertilisation. The up of the 

 hypucotyl is now piercing the plug. 



Fmbryo (enlarged) sh(.)\\n in Fig. 13. 



Fruit, ten weeks after fertilisation. The grv)wing hypo- 

 cotyl has now pierced the plug. 



Embryo shown in Fig. 15. 



Fruit, nearly sixteen weeks after fertilisation. 



Full-grown fruit, just before the detachment of the seedling 

 from the tree. The long tapering plumule is inclosed 

 in the tube of the cotyledonary body. The point of 

 detachment of the seedling is indicated l)y H< . 



The cotyledonary liody of Fig. 18. 



Fruit with two seedlings in different stages of growth 

 (given in the first plate). 



Fruit, about four weeks after fertilisation. (The shaded 

 portion is the calyx-tube or cup, in the midst of which 

 rises the style. ) 



Germinating seed. 



Germinating fruit, about eight weeks after fertilisation. 



Germinating fruit, about ten weeks after fertilisation. 

 Here the growing hypocotyl, carrying the style with it, 

 has pushed upwards the lining membrane of the tioor of 

 the calyx-tulje, which has ruptured and forms a cap on 

 its extremitv. 



Germinating fruit,

thirteen or fourteen weeks after 



Fruit with full-grown seedling just before its detachment
