ORDER LXXXVIII. VERBENACE^E. VERVAINS. 



Herbs (or generally shrubs and trees) with opposite, exstipulato leaves. Flowers 

 with a bilabiate or more or less irregular monapetalous corolla. Stamens 4, didyna- 

 mous, rarely equal, sometimes only 2. Style 1. Fruit dry or drupaceous, 2 to 

 4-celled (l-celled in Phryma) forming as many 1-seeded nutlets. Seeds erect or 

 pendulous, with little or no albumen. 



Genera 56, species 700, the herbs chiefly natives of temperate regions, the shrubs and trees of 

 warm and tropical regions, where in some instances they are very large. The Teak-tree (Tcc-

 100 feet in height The wood is'grcatly durable, and contains silex. Medicinal properties un- 

 important. The order affords many fine ornaments for the garden.
