Suffrutescent herbs; stems hollow, arching or sprawling, 1-3(-4) m tall, gla-brous below and sparsely to densely dendritic-pubescent above. Median cauline leaves with blades oblong to elliptic, 5-15(-21) cm long, 2-5(-8) cm wide, apically acute to abruptly acuminate or less commonly rounded, basally rounded to gradually tapering, marginally sharply denticulate with 6-10, 0.2-0.5 mm long teeth per cm, glabrous or nearly so above except on the principal veins, beneath sparingly to densely dendritic-pubescent; petiole (-0.5)1-3(-4) cm long. Flow-ers solitary in the axils of the upper leaves, ca. 5 cm long; pedicels glabrate to densely dendritic-pubescent, 4-9.5 cm long; bracteoles 2, linear-filiform, 1-2 mm long near the pedicel base; hypanthium hemispheric, 3-5 mm high, sparingly to densely pubescent with dendritic trichomes; calyx lobes narrowly triangular, entire to moderately denticulate, acute, sparingly dendritic-pubescent, (1.6-) 2-4(-6) mm long, more or less erect, green to dark purplish; corolla dull red-dish to orange externally, yellowish within, moderately to densely dendritic-pubescent externally and glabrous within, the tube (1.5)2-2.8 cm long, slightly curved, the contracted portion just above the somewhat swollen base ca. 7-10 mm long, 2-3(-4) mm in diameter, then expanding above to 7-8(-10) mm in di-ameter, the lobes falcate, acuminate, the 2 upper lobes 8-12 (-15) mm long, the lower 3 lobes 5-9 mm long; filament tube 3-3.7 cm long, conspicuously exserted, softly pubescent throughout with unbranched hyaline trichomes, basally distinct and adherent to the contracted basal section of the corolla tube; anther tube 7-8 mm long, the 2 shorter anthers conspicuously white-tufted apically, the anthers otherwise glabrous or with a few elongate trichomes (1-)2-3 mm long on the connectives. Berries leathery, surmounted by a 1-3 mm high rim; seeds short-ellipsoid, flattened, foveate-reticulate.
