 regular, campanulate, rotate or bilabiate, upper lip bilobed, lower trilobed ; aestiva- 

 tion imbricate. STAMENS inserted on the corolla-tube, normally as many as and 

 alternate with its lobes, but often fewer, the posterior being absent or rudi- 

 mentary, the other 4 being didynamous; sometimes the 2 anterior are, like the 

 posterior, sterile or wanting ; anthers 2-celled, often 1-celled by the confluence of 

 the sutures across the top of the connective. CARPELS 2, antero-posterior, cohering

 dally or septifragally 2-valved ; valves undivided, bifid or bipartite, sometimes opening 

 at the top by 2-3 valvules, or operculate. SEEDS horizontal, ascending or pendu-
