Description Moderately robust, shortly stoloniferous perennial herbs; rhizome 2–4 cm long, 8–15 mm diameter. Cataphylls 6–10, elliptic to lanceolate, 7.5–12 x 1.6–2.1 cm, maroon or brownish maroon. Culm 1- to several, erect, lateral, 5–20 cm x 2–4 mm, glabrous, brownish or maroon red. Leaves basal, up to 47.5 cm long; leaf blade oblong or linear oblong, 11–32.5 x 3–7.6 cm, apex abruptly narrowed or cuspidate with cauda c. 3–4 cm long, base gradually narrowed into a short pseudopetiole which widens into the sheath, coriaceous to subcoriaceous, papey when dried, upper surface greenish, dull, lower surface reddish purple with maroon nerves (in living material), 3-nerved, secondary nerves distinct, flat in cross-section, margins entire to serrulate or more or less scabrid near apex; pseudopetiole 10–20 x 1.5–2.5 cm, sheath lanceolate, 4–6.5 cm x 4–15 mm, apex very gradually narrowed, coriaceous, reddish green to maroon. Innovlucral bract 3–5, glumaceous, ovate to lanceolate, 2.5–4.5 x 0.6–0.8 cm, basal bract shorter, coriaceous; peduncle slender, 8–14 cm long. Inflorescence terminal, ovoid to lanceolate, composed 1–4 spikes; spikes remaining ± obscured b floral bracts even at maturity, ovoid-lanceolate, 1.4–2.5 x 1–1.4 cm; spicoid bracts lanceolate, 1–1.2 x 0.6–1 cm, coriaceous, nerves indistinct; floral bracts, free, lowest 2 bracts linear to linear lanceolate, 5–8 mm long, keeled, wingless, hispid, upper bracts linear, flat to ± keeled, glabrous; staminate flowers 3 per spicoid, anther linear, 2–2.6 mm long, stigma branches 3, style 5 mm long. Fruit not seen. [details]

Fruit not seen. [details]

Diagnosis Resembles M. sapuaniana by the presence of several cataphylls and maroon leaf sheaths but differs by floral morphology. M. zinnirahae has single spike (up to 2.) smaller spicoid bracts and ovoid spikes, whereas M. sapuaniana occasionally has 3 spikes with sessile terminal capitulum, larger spicoid bracts and angular spikes. [details]

Etymology Named in honour of Zinnirah Shabdin for her contribution to the study of the genus in Sarawak. [details]
