 3 — 4 pairs below, and confluent bipinnatified by 3 — 9 lobes 

 above, the lobes nerveless, obtuse, and unequally toothed; 

 general outline broadly lanceolate, 4 — 6 inches long, 2 — 2J 

 wide, diminishing above, but never entire, nor lobes parallel

 lines long, and somewhat broader, exceeding the calyx, 

 border of 5 rounded lobes, appendages manifest between 

 filaments enclosing their base, stamens and style exserted, 

 filaments naked, attached to the base of the corolla, style,
