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.

persistent, appearing with or after flowers and continuously all summer, decumbent or sprawling to ascending, nearly green with various degrees of red or purple veins, or suffused reddish or purplish to nearly uniformly purplish red, without white areolae, urceolate (gently S-curved like a hunter’s horn), 5–25(–45) cm (bulging distal of middle, 3–6 cm at widest point), firm, sometimes shiny or waxy, external surface glabrous or glabrate to densely pubescent, wings 1–3(–4) cm diam.;

orifice round to oval, (gaping, with rainwater held in pitcher), 1.4–3.6 cm wide, rim green to purplish red, (thick, flaring), loosely revolute, scarcely or not indented distal to wing, (0.7–3.1 mm wide at thickest point);

hood erect or with lobes arched together over orifice, same colors and veined as pitcher, reniform, undulate or entire, 2–5 × 3–7 cm, wider than long, basal lobes cordate, attached to sides of rim of orifice with no neck, distal portion somewhat abaxially recurved and notched apically, apex not apiculate, adaxial surface with decurved setae 0.6–1.8(–3) mm.
