ORDER CXLIIL— VERBENACEiE.— THE VERVAIN 

 TRIBE. 



The genus Verbena is well known, from the 

 many beautiful species now common in every 

 greenhouse. The fruit is two or four celled, 

 and a drupe or a berry, and the calyx of the 

 flowers is tubular, and persistent round it ; but 

 the corolla is deciduous, and falls oflP long 

 before the fruit is ripe. In the genus Verbena 

 the calyx is tubular, with five distinct angles, 

 ending in five teeth. The corolla has a cyHn- 

 drical tube nearly double the length of the 

 calyx, and a flat hmb divided into five unequal 

 segments, which are wedge-shaped and notched, 

 the central one of the lower three appearing to 

 have been slightly pinched ; the throat of the 

 corolla in hairy. There are four stamens, two 

 longer than the others, the anthers having two 

 widely-spreading lobes, as in the Labiatse. The 

 style is slender below, and thickest in the 

 upper part ; and the stigma is two-lobed. The 

 leaves are opposite, and furnished with stipules
