LYI. URTICACE^. 



Flowers apetalous, mostly unisexual. Stamens uniseriate, inserted into the torus, opposite 

 to the calyx-divisions. Ovary reduced, one-celled : ovule single : styles 2-1, usually fur-

The rich milk of Artocarpece is either poisonous, or wholesome : it contains often an 

 abundance of caoutchouc (Ficus), or bird-lime is prepared from it (Artocarpus). The 

 tenacity of the fibres is remarkable in Urticece proper. The syncarpia, or fruits, or seeds, 

 are eatable in several instances {Artocarpus, Madura, Brosimum). Drugs are obtained 

 from the root of Contrajerva (Borstenia), and from the Trumpet-tree (Cecropia). The 

 Fustic-wood (Madura) contains a yellow pigment. Several West Indian Urticacea are 

 valuable timber-trees (Artocarpus, Brosimum, Pseudolmedia, Ficus laurifolia, etc.).
