Description

Readily forms a branched stem up to 10 m long that climbs and scrambles through surrounding vegetation.
The lamina is linear, up to 28 cm long and 6 cm wide. The apex of the leaf is acute or obtuse and the base is attenuate and petiolate. The petiole is canaliculate, up to 7 cm long, and clasps the stem. The upper surface of the lamina is green, the lower surface light green, and the stem, midrib and tendril generally yellowish green. Stems and leaves are generally glabrous, but may occasionally be sparsely covered by minute hairs, particularly towards the base of the leaves. If present, these hairs are slightly more prevalent on the lower part of the inflorescence.
The lower pitchers are up to 26 cm tall and 5.5 cm wide. The bottom third to half of the trap is ovate and variably swollen. Above this part, the width of the pitcher narrows, often forming a faint hip, and becomes cylindrical or infundibular towards the pitcher opening. Wings up to 1.4 cm wide, fringed with filaments up to 12 mm long, run down the front of the pitcher. The peristome is loosely cylindrical, up to 1.2 cm wide, and is lined with ribs up to 1 mm high, spaced up to 1.5 mm apart. The peristome may be slightly expanded at the sides of the pitcher opening. The lid is elliptic or ovate, up to 5.5 cm long, 4.8 cm wide, and generally lacks an appendage, though in some populations a vestigial appendage a few millimetres tall may be observed. The spur is unbranched and up to 14 mm long.
The exterior of the lower pitchers is yellowish green, mottled with long, dark red or purple blotches. The interior of the trap is creamy white, or light yellowish green and lightly flecked with dark purple. The peristome may be dark red or purple and both sides of the lid are yellowish green with dark purple blotches.
The upper pitchers are up to 12 cm tall, 4.5 cm wide, and are wholly infundibular, being uniformly funnel shaped or more strongly elongated. Wings are reduced to narrow ridges that run down the front of the pitcher, but these may hardly be discernable at all. The peristome is loosely cylindrical, up to 9 mm wide, and is lined with ribs up to 1 mm high, spaced up to 0.8 mm apart, but these ribs are often not apparent. The peristome may be slightly expanded at the sides and particularly towards the raised and elongated rear of the pitcher opening. The lid is elliptic or ovate, up to 4.5 cm long, 4 cm wide, and generally lacks an appendage, though in some populations a vestigial appendage a few millimetres tall may be observed. The spur is unbranched and up to 12 mm long.
The exterior of the upper pitchers is usually yellowish green, but may be a pale, whitish-green, tinged orange, pink, or red. The exterior is often mottled with dark red or purple blotches. The interior surface of the trap may be light yellow or creamy white, often faintly flecked with red or purple. The peristome is yellow, red or purple and both sides of the lid may be yellow, orange or red, often blotched with dark red, orange or purple. The colouration of the upper pitchers is usually vibrant and very attractive.
The inflorescence is a raceme, to 35 cm long. The peduncle is up to 25 cm long, the rachis to 12 cm long. Flowers are mainly borne on 2-flowered partial peduncles lacking bracts. Tepals are ovate, and the anther head is borne on a column of equivalent length to the tepals. Fruits are 15-20 mm long. A
