HETEROSTYLISM. 219 



parison of tliese minute details, is that the long-styled form 

 of flower represents a more fully developed pistil, and 

 therefore a more female condition ; while the short-styled is 

 more male : and, as we have seen above, this is borne out by 

 the comparison of the offspring ; and, lastly, by the probable 

 dioecious condition of ^giphila ohdurata, as well as by the 

 actual dioecism of some species of Mtisscenda and Morinda 

 umhellata ; while Musscenda cylindrocarpa and certain other 

 species of Morinda are hermaphrodite without heterostylism 

 (Burck, I.e.).
