 tubular-campanulate and 5-toothed ; ribs not winged and usually not 

 prominent. Corolla-tube cylinclric or somewhat enlarged above ; upper 

 outside lip erect, broad, concave, emarginate or shortly 2-fid ; lower lip 

 larger, spreading, with 3 broad subequal lobes. Stamens 4, all perfect ; 

 posticous pair affixed to the corolla-tube, usually included ; filaments 

 filiform ; anticous pair affixed to the throat ; filaments elongate, arched, 

 connivent under the upper lip, with a tooth-like or subulate appendage 

 at the base ; anthers closely approximate or coherent in pairs ; cells 

 divaricate, often confluent at the apex. Style bilamellate at the apex. 

 Ovules many in each cell. Capsule linear, oblong, ovoid or globose, 

 usually longer than the calyx, septicidal. Seeds many, foveolate-rugose.
