Rosette and lower pitchers are broadly ovoid throughout, narrowing somewhat towards the orifice. They grow up to 15 cm in height by 6.4 cm in width. A pair of fringed wings (≤2 mm wide) extends up to 2 cm below the peristome, before narrowing to ribs. These wings may bear fringe elements up to 5 mm long. The pitcher mouth is elliptic-ovate and has an oblique insertion, measuring up to 6.7 cm by 4.7 cm. The peristome is cylindrical, expanded, and up to 2.1 cm wide. It may be slightly raised at the front, forming a notch up to 1.1 cm long. It bears ribs up to 0.5 mm high and spaced up to 1 mm apart. The inner margin of the peristome is lined with very small but distinct teeth measuring 0.5–1 mm in length. The outer margin is recurved and may be to some degree. The peristome is elongated into a neck up to 6.7 cm long and 4.7 cm wide. The glandular zone covers the lower half of the inner surface. The pitcher lid is sub- to elliptic-ovate and may be up to 5.2 cm long by 3.5 cm wide. It often has a base and acute-obtuse apex. Three longitudinal veins are present on either side of the lid. A number of circular or slightly ovate nectar glands (≤ 0.1 mm wide) are concentrated on the underside of the lid, but no appendages are present. A spur measuring up to 12 mm in length is inserted around 2 mm below the apex of the neck. It may be simple (unbranched) or .
