Terrestrial climber to at least 6 m tall. Stems obtusely angular, rarely rounded, 5-9 mm diam. Leaves coriaceous, sessile, leaves at base of the climbing stems largest, thinnest and long-spathulate, up to 20 by 5.2 cm, apex obtuse to slightly acuminate, base spathulate or cuneate, clasping the stem for 1/2-2/3 its diam., decurrent for 3-4 mm at 45°, auriculate, the lobes 3-6 mm long, rarely not auriculate; towards the stem apex the leaves are shorter, oblong, 10-15.5 by 2.1-3.4 cm, and more auriculate at the base; leaves of the basal rosettes mostly oblanceolate-spathulate, 7-8.5 by c. 2.5 cm. Longitudinal nerves 3 (or 4) on each side of the midrib in the outer half, obscure in the upper stem leaves. Pennate nerves numerous, c. 80° from the midrib, overlapping the innermost longitudinal nerves, obscure in the upper stem leaves. Lower pitchers ± broadly, rarely narrowly ellipsoid in the basal 2/3 or 1/2, gradually becoming constricted to-wards the subcylindrical upper half, sometimes ± broadly subcylindrical overall, 13-21.5(-26.5) cm long, 5.5-8.5 cm wide in the basal part, 3.5-6.7(-8.2) cm wide in the upper part, with two fringed wings 2-4 mm broad, fringed elements 4-6 mm long, c. 4 mm apart, mouth ovate, acuminate towards the lid, oblique, at 45° to the pitcher axis, concave; peristome flattened (3-)8-14(-15) mm wide, ribs 1 mm apart, each interspersed with 10-12 striae, outer margin usually markedly sinuate where the peristome is widest, inner edge lacking teeth; lid broadly elliptic-ovate, 3.2-6.5 by 2.8-4.5 cm, apex rounded, base truncate to shallowly cordate, appendages absent, nectar glands scattered, concentrated along distal part of midline, orbicular, thickly bordered, 0.2-0.5 mm diam., along midline sometimes longitudinally elliptic, c. 0.8 mm long; spur simple or branched, up to 17 mm long; rosette pitchers smaller and more slender in pro-portion than the lower pitchers, peristome not usually sinuate. Upper pitchers as the lower, but either subcylindrical, 13-27.5 cm long, or very narrowly infundibular, flaring gradually from the base where 1.3-2.2(-2.6) cm wide, to the peristome where 2.6-4.5 cm wide, or slightly hipped, constricted slightly but abruptly above the basal third where 4-4.7 cm wide to a slightly narrower upper cylindrical portion 3.5-4.5 cm wide, lacking fringed elements, but with two ridges up to 1 mm wide; peristome narrower, not always sinuate, ribs 0.3 mm apart, with 5 or 6 striae. Male inflorescence 35-65 cm long; peduncle (9-)11.5-23(-27) cm long; partial peduncles 2- (or 3-)flowered, (1-) 6-10 mm long; bracts usually present, 4-5 mm long; pedicels 7-20 mm long; tepals elliptic 3 by 1.5(-2) mm long; androphore (1.5-)2-3 mm long; anther head 1-1.25 mm wide. Fruits with valves 20-25 mm long. Seeds fusiform, 10 mm long, rugose in centre. Indumentum of scattered sessile, red globular glands 0.1 mm diam. on most parts; stem glabrescent, with short white erect simple hairs, rarely 3-branched; leaves glabrescent above, below as the stems; pitchers with erect simple to 4-branched coppery hairs or with a mixture of long simple and sparsely branched hairs and short 5 or 6 armed hairs; inflorescence with appressed simple translucent hairs from peduncle to fruit valves. Colour either all green or with pitchers suffused and spotted with red-brown, inner surface blotched with red; peristome green, striped red; rarely the whole outer surface vivid red, the peristome yellow, and the inner surface lacking red pigment. Lower surface of the leaves drying brown below.A
Nepenthes sanguinea is distinguished from N. macfarlanei in the more or less sharply 3-angled, glabrescent stems, the lower lid surface either lacking or possessing very few hairs, the pitchers not abruptly contracted below the peristome, and the inner edge of the peristome lacking teeth. It is not likely that N. sanguinea would be confused with the other montane species of Peninsular Malaysia (N. ramispina and N. gracillima) since these are much smaller species with more slender pitchers.A
