Plants forming dense clumps; rhizomes 0.5-1.5 cm diam. Pitchers persistent, dying back if frozen, appearing with flowers and continuously all summer, erect, green to flushed red or solid maroon, often red-or purple-veined distally, major veins and crossveins of internal and external surfaces dark maroon-red, without white areolae, (short-petiolate, proximal solid petiolar portion to 1/4 length of pitcher, tapering gradually from base to orifice or sometimes scarcely bulging abaxially in distal portion), (6-)10-52(-57) cm, firm, waxy, external surface glabrous or puberulent, wings 0.5-2 cm; orifice oval, 0.5-3.5 cm diam., rim green to red or maroon, tightly revolute, with no or distinct indentation distal to wing, sometimes forming spout; recurved adaxially, held beyond and covering orifice, sometimes held close to orifice, green to maroon, faintly red-or maroon-veined, or conspicuously and densely reticulate-veined, all veins of abaxial and adaxial surfaces of hood and neck red to maroon throughout proximal and distal portions, without white areolae, ovate, flat to slightly undulate, 0.7-4.5 × 0.7-4 cm, longer than wide, base attenuate to cordate, scarcely constricted, neck 0.5 cm, margins entire or slightly undulate (proximal margins scarcely reflexed), apiculum 1-3 mm, adaxial surface with hairs to 0.5 mm. Phyllodia absent. Scapes 1-2, from 1 bud, 12-75 cm, usually 1.5-2(-3) times height of tallest pitchers; bracts 0.4-1 cm. Flowers strongly fragrant; sepals maroon, 1.5-2.7 × 2-2.6 cm, (margins strongly reflexed abaxially after anthesis); petals maroon to red, distal portion obovate, 2.5-4 × 1.3-2.5 cm, margins erose; style disc greenish, 2-3.5 cm diam.
