 7-15, entire or obtusely few-toothed; spikes crowded, solitary or 

 geminate, at length much elongated and slender; pedicels very 

 short; corolla white, campanulate, the lobes about half the length 

 of the tube ; the long narrow appendages nearly free from the 

 stamens; ovules about 6, rarely more, on each plancenta; cap-

 narrow spatulate calyx-lobes; seeds oval, reticulated.

 elongated-oblong or linear in outline, pinnatifid or pinnately 

 parted into several-many pairs of lobes, the terminal lobe not 

 larger nor parallel-veined ; racemes becoming elongated ; pedicels

 angular entire lobes and a much larger terminal one, the evident 

 veins of which are nearly parallel, the upper leaves commonly 

 entire and slender petioled ; pedicels shorter than the fruiting
