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.
