Sepals 5, nearly or quite distinct (in L. calycimi^ 2 anticous united 

 less than J the way up) ; posticous sepal usually much wider, often 

 longer, often pointed or subspinescent. Corolla |-1 in. in total length, 

 conspicuously 2-lipped ; tube inflated in the upper part, often with 

 dense strong deflexed hairs at the top of the cylindric portion ; posticous 

 lip ovate-oblong, emarginate, inside in the bud. Stamens 4 ; anther- 

 cells on posticous stamens 2 in typical part of genus (except by accident, 

 though often narrower than the anthers of the anticous stamens) ; in

 anthers oblong, often acute (or with mucro) at the base, one inserted
