PIMENTA (from the Spanish pimento, allspice). 

 Myrtacex. Highly aromatic trees, one species of which 

 is the allspice. 



Leaves large, leathery, feather-veined, long-stalked, 

 black-dotted beneath: fls. numerous, small, white; 

 borne in terminal or axillary, trichotomous cymes; 

 calyx-tube top-shaped; petals 4-5; stamens numerous: 

 drupe 1-2-seeded. Five or six species, native of Trqp. 

 Amer. As a genus Pimenta is distinguished from its 

 near allies (Eugenia, Myrtus) by the circular or spiral 

 embryo and the 2-celled ovary with 1-6 ovules pendu- 

 lous from the apex of each cell.
