NATURAL HISTORY OF PLANTS. 



African ; it has pointed or acuminate stipules, free or little connate, 

 and a coriaceous fruit, turbinate at the base, often nearly fusiform. 

 The seminal envelope is slightly fibrous. It is so also in the true 

 American Genipas, whose corolla is hairy at the throat and the

intrapetiolar stipules generally fall early. The ovarian cells are two 

 in number, complete or incomplete in the same species ; and this 

 latter alternative is the more remarkable as the presence of these 

 incomplete cells, corresponding to that of the parietal placentas, is 

 the only character distinguishing from the true Randias, Gardenia^ 

 (fig. 297-301), beautiful plants from the tropical regions of the old 

 world, and especially Rothmannia," whose large and showy flowers ' are 

 axillary or terminal, most frequently solitary or geminate. The species

 tropical Africa, may have only one parietal 

 placenta (Hieen, Jmrn. Bot. [1878] 97, t. 196).
