ORDER LIX. VEKBENA'CEJE. (VERVAIN FAMILY.) 



Herbs (with us), with opposite leaves, didynamous stamens, 

 and corolla either irregularly 5-lobed or 2-lipped. Ovary in 

 Verbena 4-celled (when ripe splitting into 4 nutlets) and in 

 Phryraa 1-celled, but in no case 4-lobed, thus distinguishing the 

 plants of this Order from those of the next.
