XIV. DIDYNAMIA. The flowers of this class

 divided into five or two lipped segments, which 

 are unequal and persistent. The corolla is of one 

 petal ; the upper lip concave, and sometimes bifid j 

 the lower lip trifid. In the first order, the so- 

 called GYMNOSPERM^E, the germander, lavender, 

 mint, dead-nettle, and many others of similar
