 sometimes occurs in more conspicuous and remarkable forms. 



328. Occasionally it is elongated, as in some plants of the Caper 

 family (Fig. 276), making the flower really look like a branch, hav-

 covering its whole surface (Fig. 277). But at maturity, the five 

 small and one-seeded fruits separate, and so do their styles, from the 

 beak, and hang suspended from the summit. They split off elasti-
