 reous with short viscid pubescence ; leaves obovate-spatulate or cuneate-oblong 

 to oblanceolate, repand to incisely pinnatifid ; calyx when young villous-viscid ;

 spots at the base ; the plaited border somewhat 5-lobed or barely 5 - 10-toothed. 

 Stamens 5, erect ; anthers separate, opening lengthwise. Herbs (in this coun- 

 try), with the leaves often unequally in pairs, and the 1 -flowered nodding pe- 

 duncles extra-axillary; flowering through the summer. (Name <f>vo-a\is, a 

 bladder, from the inflated calyx.)

 sharply and irregularly laciniate-toothed ; peduncles filiform ; corolla unspotted, 

 very small (3 - 6" broad when expanded) ; fruiting calyx conical-ovate with a 

 truncate or sunken base, 10-angled, loosely inflated, at length well filled by the 

 greenish-yellow berry. Open rich grounds, Penn. to Minn., and southward.
