 sometimes occurs in more conspicuous and remarkable forms. 



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

 family (Fig. 27G), making the flower really look like a branch, hav-

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

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