GENUS F/.— MIMULUS. Linn. 



Calyx tubular, 5-anglcd, 5-tootlied. Corolla tubular, bilabiate 

 and ringent ; the upper lip erect, 2-lobed, the lower one sub-erect 

 or spreading, 3-lobed. Stamens 4, didynamous ; anthers 2-celled, 

 the cells at length confluent. Stigma with 2 flat oblong irritable 

 lobes, closing when touched. Capsule ovoid or fusiform, 2-valved, 

 opening loculicidally. Seeds numerous, minute, not winged.

The name of this genus of plants appears to have come from the Latin word mimo, 

 I mimic ; hence Monkey- flower.
