4. FEMALE, such as upon the same root bear fe- 

 male flowers only, as in the class Dioecia. 



5. POLYGAMOUS*, such as either on the same, or 

 on different roots bear hermaphrodite iiowers of 

 either or both sexes, as in the class Poly garni a. 



Of plants that are Polygamous oa tlie.sa/ne root, 

 there are three cases: 1st, Afale Hermaphrodite and 

 Female -Hermaphrodite flowers; which is a rare case, 

 but is observed in Musa. 2d, Hermaphrodite^ and 

 Male flowers, as in Veratrum, . Celtis, ^Egilops, and 

 Valantia. 3. Hermaphrodite and Ftmale flowers, as 

 in Parietaria and Atriplex. 



Of such as are polygamous on two distinct roots, 

 the cases are four ; 1 st, Hermhphrodite^ flowers and 

 Male, as in Panax, Nyssa, and Diospyros. 2d, Her- 

 maphrodite flowers and Female, as in Fraxinus. 3d, 

 Hermaphrodite^ flowers and both Male and Female, 

 as in Gleditsia. 4th, Androgynous^ and Male, as 

 in Arctopus. Of plants that, are polygamous on three 

 distinct roots there is but one case, viz. Androgy- 

 nous, Male and Fejnale, as in Fie us **. 



* See the signification of this term explained in the account 

 of the title of the class Polygamia, in Part II. Chap. xxvi. 

 These plants are by some called Hybrid, mongrel. 



f In the Philisophia Botanica, the hermaphrodite flowcri 

 of this class are put down Hermaphroditae, Female Hernia, 

 phrodite ; but the instances shew it to be a mistake. 



+ Hermaphroditae, again in Phil. Bot. 



|| Hermaphroditae again. 



In the Gleditsia, which is the only known instance of this 

 case, the male flowers and the hermaphrodites are produced 

 upon the same plant, and the females on a distinct one. 



^f This case and the next, having no hermaphrodite flowers, 

 seem to be exceptions to the definition of polygamous plants. 



** The instance of this case given in the Philosoptiia /?o- 

 tanica is the Empetrum ; but that Genus is removed to the 

 class Dioecia in the last edition of the Genera Plantarum ; 

 where a note informs us, that the hermaphrodite flowers, which 

 the author had once seen on a plant of this Genus, could not 

 afterwards be ever found again. We have therefore changed 

 this instance for the Ficus, the only other instance left of this 

 singular case,
