Description Slender perennial with a short rhizome, 25‒65 cm tall. Culms tufted, erect, trigonous, smooth, or striate, 0.8‒1.5 mm wide. Sheaths yellowish-brown to dark brown. Leaves all basal, less than half length of inflorescence culm. Lamina erect, flat or canaliculate, straight, 0.3‒0.6 mm wide, ciliate or scabrid on the margins. Ligule membranous. Involucral bracts 1‒4; longer or shorter than the inflorescence, erect, or oblique. Inflorescence simple or once compound, panicle-like, 2‒6-branched, 3‒6 cm long. Spikes 1‒10, sessile, or pedunculated, ovoid, spreading, or erect, dense, 5‒13 mm long, 1.5‒15 mm wide. Spikelets erect, ovoid, oblong, oblong-ovoid or cylindrical, open or dense, acute, 5‒13 mm long, 1.5‒2.5 mm wide, 10‒26-flowered, pedicellate or sessile, straight, 1‒14 per cluster, stramineous or pale brown to brown. Stamens 3; anthers linear, 1.2‒1.5 mm long, connective setulose. Rachis angular but not broadly winged. Glumes spirally arranged, membranous, ovate, narrowly ovate or ovatelanceolate, 2.8‒3.4 mm long, 1.2‒1.5 mm wide, apex acuminate, with a straight mucro, surface glabrous, keeled with an arcuate keel, 2-nerved, sides nerveless, margin glabrous. Rachilla persistent on rachis after glumes and achenes have fallen off, winged. Style deciduous, longer than stigmas, longer than achene, fimbriate, flat, dilated at the base. Stigmas three. Achene obovoid, trigonous, margins obtuse, 0.9‒1.1 mm long, 0.5‒0.7 mm wide, with 3 longitudinal ribs, surface with fine, longitudinally linear cells in many vertical rows, tuberculate with age, apex apiculate or truncate, base stipitate.

Distribution Fimbristylis buchananensis is endemic to Queensland and has been found from c. 90 km north of Hughenden to as far south as Aramac, with most collections around Lake Buchanan and Lake Constant. Most collections have been around lake foreshores, on old sand dunes or remnant lake beds. [details]
