NATURAL HISTORY OF PLANTS. 



of the fruit as a long plume covered with hairs which render it quite 



feathery (fig. 93). Other species form a transition between these,' 

 as these hairs are only developed on the lower part of the 

 ^tyle, leaving the stigmatic portion naked ; such, for 

 example, is C.fuilhla Raoul (fig. 94). 



C. curliom L. and some nearly allied species have 

 been grouped by De Candglle' into a separate section, 

 as the flower possesses an involucre formed of two lateral 

 bracts, cohering for a great part of their length, and 

 entirely enclosing the bud when young. The calyx has 

 here also four sepals. Above this the receptacle becomes 

 ovoidal, bearing numerous stamens, each with a fila- 

 ment flattened below, and an anther whose lateral cells 

 dehisce by somewhat introrse clefts. The surface of the 

 style is almost entirely covered with long villi. 



Finally there are species of this genus where the 

 flowers become polygamous or monoecious by the abor- 

 tion of one set of sexual organs, and other species where 



the flowers of different sexes grow on different plants, as in C. diceca 



L. which grows at the Antilles.^

De Candolle again replaced it)," because its flowers possess corollas.
