PEINCIPAL GENERA. 

 Stilbe. Campylostachys. 



This small family approaches Verbenacea in the hypogynous irregular anisostemonous corolla, the 

 2-carpelled ovary, the erect and anatropous ovules, the spiked inflorescence, and the non-alternation of its 

 leaves ; but Verbenaceee differ in the didynamous stamens, fleshy fruit, and exalbuminous embryo. 



Selaginece, Myoporinea, and Globulariece are similarly allied with Verbenacea, and in addition their
