Rosette and lower pitchers are cylindrical throughout. They usually grow to 20 cm in height by 4 cm in width, although exceptional specimens up to 28 cm have been recorded. A pair of fringed wings (≤5 mm wide) runs down the ventral surface of the pitcher and bears fringe elements measuring up to 10 mm and spaced 6 mm apart. The glandular region is restricted to the lower portion of the pitcher's inner surface. The glands are small, overarched, and occur at a density of 600 to 650 per square centimetre. The waxy zone is reduced. The pitcher mouth is positioned horizontally at the front, becoming elongated into a neck at the rear. The peristome is flattened and expanded (≤12 mm wide), but bears only indistinct teeth (≤0.3 mm long). The inner portion of the peristome accounts for around 51% of its total cross-sectional surface length. The pitcher lid or operculum is very narrowly ovate in shape and has a distinctive basal crest on its lower surface. An unbranched spur measuring up to 10 mm in length is inserted near the base of the lid.
