Leaves are and . The lamina (leaf blade) is linear to slightly or narrowly elliptic and measures up to 18 cm in length by 3 cm in width. Its apex is acute or obtuse, whereas the base is slightly and clasps the stem for half to three-quarters of its circumference. It is also slightly and has an oblique attachment to the stem. The laminar base may be down the stem to varying degrees or not decurrent at all. Three longitudinal veins are present on either side of the midrib and restricted to the distal third of the lamina. veins are abundant and run obliquely to the laminar margin. The tendrils are proportionately very long, especially those bearing lower pitchers, which may be more than 30 cm long.
