Erect or decumbent herbs ( 15-) 30-50( -90) cm high; stems short-pubescent to nearly glabrous. Leaves sessile, membranous, elliptic to oblanceolate, coarsely and irregularly repand-dentate with 15-20 large teeth as well as callose-dentic- ulate with 4-6 times as many small teeth, mostly (5-)10-20 cm long, (1-)2-5 cm wide, apically acute, basally cuneate. Flowers with the pedicels 4-8 mm long bearing almost basally a pair of filiform bracteoles 2-4 mm long; hypanthium 6-10 mm long, obconic, angulate, strongly 10-ribbed, spreading short-pubescent; calyx lobes linear, erect, 10-18(-22) mm long, ca. 1 mm wide, marginally callose- denticulate, spreading short-pubescent, rarely glabrous; corolla white to white with pale greenish veins, puberulous, the tube 5-13.5 cm long, (1-)2-4 mm in diameter, the lobes subequal, spreading, 1.3-2.7 cm long, elliptic-lanceolate; filament tube glabrous, the anther tube slightly curved, the shorter anthers ca. 3 mm long, the longer anthers about 5-6 mm long. Capsules 1.2-2.0 cm long, pendent, often appearing more completely inferior than they actually are due to the closely enveloping free rim of the hypanthium; seeds ca. 0.8 mm long.
