Description Perennial herb with short rhizome with stiff fibres. Culm 35–100 cm × 1.5–4 mm, striate, minutely puncticulate. Basal leaves crowded, distichous; leaf sheaths four to six cm long, indistinct, straw-coloured to purple, multiveined; leaf blades c. 27–60 cm × 2.5–5 mm, flat, indistinctely keeled, tapered at the tip, edges minutely serrulate. Cauline leaves 3–4, very distant; leaf sheaths, long, green-purplish, mouth oblique. Inflorescence an elongate panicle, 30–85 cm long, with c. 9–11 partial inflorescences, distantly spaced; inflorescence bracts longer than the partial inflorescence they subtend, sheaths purplish. Peduncles unequal, up to c. 12 cm. Pedicels of the spikelets erect, flattened, margins slightly scabrid, 4–15 mm long. Spikelets oblong-lanceolate, 5.5–7.5 × 1.5–2 mm, somewhat flattened. Glumes 5–8, distichous, lanceolate-ovate, acuminate, reddish-black, with colourless-whitish margins; lower glumes empty, scabrid on the midvein, mucronatae-aristulate; two upper glumes fertile, barely mucronate; rhachilla short and erect. Flowers 2, lower bisexual, upper male. Perianth bristles 6, longer than the nutlet, pale to rusty-coloured, antrorsely densely ciliate-scabrid. Stamens 3; anthers linear yellow; connective short, bent, purple. Style trifid, base elongate-conical, triquetrous, pale, margins hispidulous, persistent. Nutlet swollen-trigonous, longitudinaly trisulcate, pale, smooth, 2–2.3 mm long, base long cuneate; beak narrow, 2–2.5 mm long. [details]

Distribution Endemic to the Mascarene Islands of La Réunion and Mauritius. [details]

Ecology Costularia melicoides prefers mid to higher elevation on the island of La Réunion: (500–)900–1,700 (–2,000) m where it occurs in ericoid thickets (avounes), moist tropical forest, forest with Acacia heterophylla (tamarinaie), and humid tickets with Pandanus (C. Fontaine, 2018, personal communication). However, in Mauritius, it is found on boulders or in clumps in seasonally-flooded upland marshes near Petrin in the Black River Gorges National Park at elevations of c. 600–700 m, in upland marshes and thickets in Perrier Nature Reserve at c. 550 m in elevation, and in the district Flacq it was found at an elevation of 280 m.
Flowering specimens were collected in February (La Réunion) and June (Mauritius), fruiting specimens were collected in April and May and from October to January (La Réunion). [details]
