THE HOP PLANT. 21 



The parts of the actual flower are ^ : — 



(a) A delicate perigonium enclosing the ovaries half way- 

 round. 



(b). A pistil with tWo thickly papillated stigmata and a 

 single ovule. 



According to Holzner and Lermer, the position of the 

 spicules on the spindle is usually alternate, and occasionally 

 decussate. The upper members, are stunted and their flowers 

 imperfect, the latter haying no clearly developed stem, and 

 their pistils, even when present, having 'no stigmata or 

 ovules. In these stunted portions the caulome is no longer 

 divided into axis and, bracteole. The apex of the spindle is 

 formed of d, small cone, soiiewhat deeply embedded within 

 a leaf whorl composed of bracts of the stunted and upper- 

 most develt|ped spicules. 



The Fruit and its Glanditlar Structure. 



The Fruit and Seed. 



The stage of fructification develops as vegetation pro- 

 gresses, whether fertilisation has occurred or not. The 

 stigmata shrivel up, and the bracts and bracteol'ps increase 

 in size ; the former being smaller at the upper- and lower 

 parts of the cone than at the centre. They are convex in 

 shape and pointed, the length being about | inch when ripe. 

 The bracteoles project a little beyond the bi-acts, and are 

 rounded at the tips, the base being incukved at the sides so 

 as to almost entirely enclose the fruit when the latter is 

 present (Fig. 10). The cone (Fig. 11) which, in an agri- 

 cultural sense, constitutes the fruit, is known in Grermany 

 by various names : Hopfendolde, Hopferling, Trolle, Dolle;
