they are globular, as in Mercurialis annua (fig. 358) ; at other times 

 linear or clavate (fig. 362), curved (fig. 363), flexuose, sinuose, or 

 anfractuoae {anfraotus, winding), as in Bryony and Gourd (fig. 364). 

 The lohes of the anther are sometimes in contact throughout their 

 •whole length (fig. 361), at other times they are separate (figs. 358,

365). In the former ease their extremities may be rounded, forming 

 a cordate anther (fig. 354), or the apex may be acute (figs. 344, 345) ; 

 in the latter case the lobes may divide at the base only, and end in a 

 sagittate or arrow-like manner (fig. 366 I); or at the apex, so as to 

 be hifurcate or forked (fig. 367 ^) ; or quadrifurcate, doubly forked
