lamina is usually obtuse-rounded in rosettes and obtuse-acute on leaves of the climbing stem, but may also be acuminate-acute. It may be sub-peltate in some specimens, with the tendril attachment being located subapically, up to 9 mm from the laminar apex. The midrib may be flattened or sunken on the upper surface and bulges outwards on the lower. Two to four longitudinal veins are present on either side of the midrib. Pinnate veins are distinct on the upper surface of the lamina and indistinct on its underside. Tendrils are up to 32.1 cm long and may or may not have a loop. 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 sinuate 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-orbicular to elliptic-ovate and may be up to 5.2 cm long by 3.5 cm wide. It often has a cordate 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 trifid. Upper pitchers are similar in most respects to their lower counterparts. They are broadly infundibular in the lower third and ovoid above, narrowing below the pitcher opening. They are also larger,
