Description

Terrestrial climber 0.3-2.5 m tall. Stems terete, or slightly angular, 3-5 mm diam., internodes 0.8-2 cm long. Leaves coriaceous, sessile, narrowly elliptic, 8-15 by 1-1.8 cm, apex acute, base barely attenuate, clasping the stem for 1/2-3/4 its circumference, slightly auriculate, obliquely attached, not or only slightly decurrent. Longitudinal nerves 3 on each side of the midrib, in the outer 1/3. Pennate nerves numerous, running obliquely to the margin. Lower pitchers ovoid-ellipsoid to subglobose, 4-9 by 3-5 cm, with two densely fringed wings, wings 6-10 mm broad, fringe elements 5 mm long, often in groups of 3, groups 0.8-1.3 mm apart; mouth suborbicular to broadly ovate, ± straight, slightly oblique; peristome subcylindrical to flattened, 5-8 mm broad, ribs 0.7 mm apart, c. 0.2 mm high, outer margin entire or slightly sinuate, revolute, inner margin finely dentate, teeth c. 1 mm long; lid ovate to broadly ovate, 2-3.5 by 1.5-3.5 cm, apex rounded, base shallowly cordate, lower surface lacking appendages, nectar glands few, only 5 or 6, sparsely scattered, pit-like, deep, unbordered, transversely elliptic or circular, 0.2-0.4 mm long; spur entire, 1-5 mm long. Upper pitchers reported as infundibuliform, 7.3-7.5 by 2-2.5 cm, but upper pitchers not formed in flowering specimen seen. Male inflorescence 10-15 by 1 cm; peduncle 6-9 cm long, 1 mm diam.; partial peduncles 1-flowered, c. 40; bracts absent; pedicels 3-4 mm long; tepals ovate, 2-2.5 by 1-1.2 mm; staminal column c. 1.5 mm long; anther head diameter unknown. Fruit valves 17-20 mm long. Seed unknown. Indumentum absent from stems and leaves; pitchers and inflorescence inconspicuously ferruginous-tomentose, hairs simple, 0.1 mm long, tepals minutely tomentose, staminal column glabrous. Colour of pitchers yellowish or reddish with diffuse purple spots; peristome yellow.A

Notes

Nepenthes bellii is unusual in the subglobular pitchers, with very densely fringed wings, the fringed elements c. 1 mm apart (cilia trifid) on tendrils up to twice as long as the blades. Not easily confused with any other species besides N. argentii. The lower pitchers of N. tomoriana, only recently collected, also bear a remarkable resemblance to those of N. bellii. However, the affinities of N. bellii may be with the Insignes group (N. burkei, N. insignis, N. merrilliana, N. sibuyanensis, and N. ventricosa).A

Distribution (General)

Philippines: Mindanao (Surigao Province).A

Habitat

Possibly on ultramafic substrate; 250-800 m. Little ecological information is available on this species. However, the localities known appear to coincide roughly with ultramafic areas in Surigao.A
