HETEROSTYLISM. 219 



parison of these 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-stjled is 

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

 the comparison of the offspi-ing ; and, lastly, by the probable 

 dioecious condition of jEgipliila ohJurafa, as well as by the 

 actual dioecism of some species of Miisscenda and Morinda 

 umbellata ; while Musscenda cylindrocarpa and certain other 

 species of Morinda are hermaphrodite without heterostylism 

 (Burck, I.e.).
