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 Fig. 361.
