Description Robust, rhizomatous; rhizome 13–15 mm diameter. Culm solitary, more or less erect or lateral, 5–27 x 0.5–0.9 cm, terete, mostly scabrid, medium greenish when fresh and becoming brownish when dry. Leaves basal, crowded and distinctly 3-ranked, up to 155 cm long; leaf blade narrowly linear, 122–145 x 2–2.5 cm, apex gradually narrowed, acuminate with long acumen, 8–10 cm long, base very gradually narrowed into sheath, coriaceous, medium green when fresh and becoming brownish when dry 1-nerved to indistinctly 3-nerved, secondary nerves indistinct with septate-nodulose when dry, strongly inverse w-shaped in cross-section, margins densely serrulate, pseudopetiole absent, sheaths lanceolate, 6.2–10 x 1–2 cm, apex very gradually narrowed, thickly coriaceous, shiny, mid– to –dark chocolate brown. Involucral bract 2–4, glumaceous, lanceolate, 20–24 x 3–5 mm, apex acuminate, dark chocolate brown. Inflorescence up to 10 or more per plant, terminal capitulum, composed of 3 spikes, seldom with solitary spike; spikes rounded to lanceolate, 10–20 x 5–8 mm, acute to obtuse, or sub-obtuse, greenish brown; spicoid bract lanceolate, 5–8 x 6–8 mm, subobtuse, subcoriacoues, greenish brown, light brown along the margin edge, faintly with hairs, nerves indistinct; floral bract 6, free, lower 2 bracts linear, 4–5 x 0.6–1 mm, acute, mid-brown, keeled, wingless, hispid to ciliate hispid, upper bract linear-lanceolate, 3.8–4.6 x 0.4–0.8 mm, acute flat to keeled, transparent light brown, staminate flowers 4 per spicoid, anther linear, 6 mm, stigma branches 2, c. 2 mm long, whitish; style 4 mm long. Fruit obovoid, 5–6 x 2–3 mm, apex with extended conical, keeled, base shortly stipitate, exocarp hard, rugose at the upper part and with small tubercles at lower part, brownish at the lower part and become darker toward the apex and apex blackish. [details]

Description Robust, rhizomatous; rhizome 13–15 mm diameter. Culm solitary, more or less erect or lateral, 5–27 x 0.5–0.9 cm, terete, mostly scabrid, medium greenish when fresh and becoming brownish when dry. Leaves basal, crowded and distinctly 3-ranked, up to 155 cm long; leaf blade narrowly linear, 122–145 x 2–2.5 cm, apex gradually narrowed, acuminate with long acumen, 8–10 cm long, base very gradually narrowed into sheath, coriaceous, medium green when fresh and becoming brownish when dry 1-nerved to indistinctly 3-nerved, secondary nerves indistinct with septate-nodulose when dry, strongly inverse w-shaped in cross-section, margins densely serrulate, pseudopetiole absent, sheaths lanceolate, 6.2–10 x 1–2 cm, apex very gradually narrowed, thickly coriaceous, shiny, mid– to –dark chocolate brown. Involucral bract 2–4, glumaceous, lanceolate, 20–24 x 3–5 mm, apex acuminate, dark chocolate brown. Inflorescence up to 10 or more per plant, terminal capitulum, composed of 3 spikes, seldom with solitary spike; spikes rounded to lanceolate, 10–20 x 5–8 mm, acute to obtuse, or sub-obtuse, greenish brown; spicoid bract lanceolate, 5–8 x 6–8 mm, subobtuse, subcoriacoues, greenish brown, light brown along the margin edge, faintly with hairs, nerves indistinct; floral bract 6, free, lower 2 bracts linear, 4–5 x 0.6–1 mm, acute, mid-brown, keeled, wingless, hispid to ciliate hispid, upper bract linear-lanceolate, 3.8–4.6 x 0.4–0.8 mm, acute flat to keeled, transparent light brown, staminate flowers 4 per spicoid, anther linear, 6 mm, stigma branches 2, c. 2 mm long, whitish; style 4 mm long. Fruit obovoid, 5–6 x 2–3 mm, apex with extended conical, keeled, base shortly stipitate, exocarp hard, rugose at the upper part and with small tubercles at lower part, brownish at the lower part and become darker toward the apex and apex blackish. [details]

Diagnosis Mapania kadimiana closely resembles M. spadicea Uittien differing by having three spikes in sessile terminal capitulum (vs solitary spikes not forming a capitulum).  [details]

Ecology At present this species is recorded from the type locality only where it occurs lithophytically or on slopes in wet or damp places, often near to streams under mixed dipterocarp forest. [details]

Etymology This species is named after the Vice Chancellor, Universiti Malaysia Sarawak, Prof. Dato’ Dr. Mohamad Kadim Suaidi for his continual support of the biodiversity research in
Sarawak. [details]
