 leaves ; flowers diclinous ; petals usually six, with a stamen before 

 (opposite to) each one ; carpels usually three, distinct and one-seeded. 

 Species eighty to one hundred, principally tropical. They generally

 even poisonous.

 States, is a beautiful climber deserving cultivation in ornamental gar- 

 dens. Its only congener is a native of Eastern Asia. (Figs. 55478.)

Two other genera, Calycocarpum and Cocculus, are represented in 

 the United States. 



Many of the Old World species are more or less in repute as furnish- 

 ing medicines, but none are of sufficient importance to be particularly 

 noticed. 



Order Anonacese. Trees and shrubs with alternate leaves ; flowers 

 trimerous ; stamens indefinite, on a thickened receptacle ; carpels gen- 

 erally indefinite. Species 400, mostly tropical. The bark generally 

 contains an aromatic and stimulating, sometimes acrid principle.
