28 FRUCTIFICATION, OR FLOWER AND FRUIT. 



Common Receptacle, being either naked, hairy, 

 scaly, or cellular, affords generic distinctions. 



64. Flos completus, a Complete Flower, is furnished 

 with both Calyx (53) and Corolla (54) ; without 

 the former, it is nudus, naked ; without the latter, 

 apetalus, apetalous. 



65. With respect to the essential organs of fructi- 

 fication; Flos perfectus, a Perfect, or United, 

 Flower, bears Stamens (58) and Pistils (59) in the 

 same individual. Flores separati, Separated Flow- 

 ers, have Stamens in one, Pistils in another. This 

 separation is absolute in Monoecious Flowers, 

 where both kinds grow on the same plant, and in 

 Dioecious ones, where they grow on two distinct 

 plants, of the same species ; but in Polygamous 

 ones there are some Perfect Flowers, as well as 

 Separated ones, on the same plant, or on different 

 ones. Neuter or Abortive Flowers have both 

 organs defective. 



66. Flos sterilis, a Barren Flower, has Stamens only 

 (65), and can consequently produce no Fruit or 

 Seed. 



67. Flos fertilis, a Fertile Flower, has Pistils only 

 (65), but produces no Seed without the assistance 

 of the Barren one (66). 



68. Flos compositus, a Compound Flower, consists 

 of numerous Flosculi, Florets, or partial flowers, 

 in a Common Calyx, the Anthers (58) of each of 

 such florets being united into a cylinder. The
