Description
Epiphytic shrublet high in trees, 0.1–0.5 m tall. Stems several from a woody rootstock ca. 2 × 5 × 2 cm, roots numerous, stout, 2 mm diam. Rosette shoots and climbing stems not seen, short stems terete, 3–4 mm in diameter, internodes 1.5–2.5 cm long, axillary buds not seen, moderately densely and persistent hairy in distal internodes, hairs white, covering ca. 50% of the surface, hairs 0.2–1.0 mm long, mainly simple, some with 2–6 erect branches from the base, either all equal or with a bristle hair longer than the others, intermixed with dark red depressed globose sessile glands 0.05 mm in diameter. Leaf blades chartaceous, drying brown on both sides, oblong-elliptic, (9.0–)11.5–13.0(–14.0) × (1.2–)2.2–3.0 cm, apex acute, not peltate, base decurrent, longitudinal nerves 2(–3) pairs in the outer half of the blade, arising from the base of the midrib, conspicuous on the upper surface; pennate nerves moderately numerous and conspicuous on the upper surface, more or less patent; midrib on both surfaces moderately densely hairy (ca. 20% cover) with white, simple, mostly appressed hairs 0.2–0.4(–0.5) mm long, on lower surface, 0.3–1.0 mm long, on upper surface, the leaf-blade otherwise with sparse simple hairs and moderately dense depressed globose red-black glands 0.05 mm diam. Petiole 2.5–4.0 × 0.4–0.5 cm, wings held flat or slightly u-shaped, clasping the stem for ½ its circumference, not, or very slightly decurrent, indumentum as leaf-blade. Tendril >50% covered in appressed hairs 0.25–1 mm long, hairs simple or basally branched, arms equal or with one long and bristle-like (Fig. 2E). Lower pitchers not seen. Intermediate and Upper pitchers (tendrils not fully coiled) subcylindrical in outline (4.5–)6.0–11.0 × 1.9–2.8 cm, often with the basal 1/2–3/5 ellipsoid, narrowing gradually and slightly about the middle to ca. 1.6 cm wide before widening slightly to the peristome, outer surface 10–30% covered in minute, 4–5-armed, stellate hairs 0.1 mm diam., mixed with sparse minute simple hairs and larger basally branched hairs 0.4 mm long, together with depressed globose glands 0.05 mm in diameter; fringed wings running from the peristome to within 1–2 cm of the base of the pitcher, 1.8–2.0 mm wide, fringed elements (0.5–)1.0(–1.5) mm long, 3–4 mm apart, held close to the pitcher surface; mouth ovate 1.1–2.1 × 1.8–2.8 cm, moderately oblique, straight to slightly concave. Peristome cylindrical 1–1.5(–2) mm wide, even in width from front to lid, 3 ridges per mm, ridges 0.10–0.15 mm high, inner edge in life inconspicuous, incurved, (Fig. 2J), when dissected and unrolled, with a line of holes, teeth absent (Fig.2 L&K), outer edge not lobed; column not developed. Lid orbicular 1.9–2.2(–2.8) × 1.8–2.0 cm, apex emarginate or rounded, base rounded or weakly cordate, lower surface lacking a basal ridge or appendage, drying brown; nectar glands more or less monomorphic and evenly and moderately distributed over the lower surface of the lid, 1.5–3 nectar glands per mm², glands large, orbicular or slightly longitudinally elliptic, borders low, rounded, (0.3–)0.4–0.6 mm long, lacunae drying black, glossy; glands slightly denser along the midline and more diffuse at the margin; red sessile peltate or depressed-globose glands 0.05 mm diam., scattered evenly; marginal areas with minute inconspicuous branched hairs. Spur simple, tapering from base to apex, acute, 4–5 mm long, moderately to densely hairy. 10–20% covered in simple hairs 0.2 mm long. Inflorescence and Infrutescence unknown.A
Notes
Excepting for Nepenthes cid, and N. truncata Macfarlane (1911: 209), all other species of Nepenthes known from Mindanao are mainly terrestrial, although a few can sometimes root on the base of trunks of stunted trees in mossy forest on mountain peaks. However, examples of high epiphytes such as N. cid, on tall trees in lower submontane forest (700 m a.s.l) are rarer. Potentially N. cid could be more common than the sparsity of the existing material indicates, but due to its inaccessibility on tall trees is rarely seen. Nepenthes cid remains incompletely known to science. Botanists in Mindanao are urged to search for this species to establish whether or not it survives, to reveal its full range and to obtain collections with inflorescences, thus far unknown.A
Conservation
The population found include less than ten individuals (two), so N. cid is here assessed as Critically Endangered under Criterion D of IUCN (2012). A
