403 



strongly bilabiate limb or with merely slight inequality of lobes, a 

 pair of bearded or naked ridges running down the lower side of the 

 throat. Stamens 4. Stigma mostly of 2 flat lobes closing together 

 when irritated. Capsule dehiscent by both sutures, dehiscent on 

 one side only, or cartilaginous and indehiscent. Seeds many. 

 (Diminutive of the Latin mimus, a comic actor, on account of the 

 gaping or grinning corolla.)

petioled . 14. M. Jloribundu*. 



Perennial; corolla about 1 in. long; calyx-teeth y 2 length of the tube; 

 leaves mostly sessile 15. M. moschatus. 



1. M. angu status Gray. Acaulescent, glabrous; leaves linear, 

 £ to 1 in. long; calyx 2 to 3 lines long; the teeth little unequal; the 

 corolla crimson, purple and yellow-dotted, with filiform tube 1 to 1£
