GENUS F/.-MIMULUS. Linn. 



Calyx tubular, 5-angled, 5-toothed. Corolla tubular, bilabiate 

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

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

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

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

 opening loculicidally. Seeds numerous, minute, not winged.

The name of this genus of plants appears to have come fi-om the Latin word mimo, 

 I mimic ; hence Monkey-flower.
