Rosette and lower pitchers are either in the lower third to half and ovoid above, or ovoid throughout. They reach 25 cm in height and 9 cm in width. A pair of fringed wings (≤15 mm wide) runs down the front of the pitcher. The glandular region covers the lower third to half of the inner surface. The glands are overarched and occur at a density of 400 to 1300 per square centimetre. The pitcher mouth is round and elongated into a wide neck. The peristome is flattened, expanded, and up to 40 mm wide. A series of teeth (≤7 mm wide) line its inner margin. The peristome ribs are spaced 0.5 to 1.5 mm apart. Pitchers bear 14 to 18 longitudinal nerves across their height. The pitcher lid is ovate and usually has a hook-shaped appendage on the underside near the peristome. A branched spur (≤5 mm long) is inserted near the base of the lid.
