Description Perennial, cinereous-green plants with stout rhizomes; culms scabrous, 50-80 cm tall, covered at base with reddish-brown reticulate sheaths; leaves rigid, reticulate, flat, 8-10mm broad, nearly equaling the culms; spikelets 5-7, distant below: the terminal 3-4 staminate, approximate, 2.5-4cm long, plump, attenuate-clavate, with lanceolate awn-pointed buff scales; other spikelets pistillate, cylindric, 4-6cm long, 0.8-1 cm broad, rather loose, sparsely flowered below, the lower ones often on smooth peduncles to 5-6cm long, drooping; lowest bract exceeding the inflorescence; pistillate scales ovate to oblong-ovate, with long reflexed subulate scabrous-margined awn, castaneo-ferruginous, 3-nerved, light brown between the nerves, longer than perigynia; perigynia coriaceous, broad-ovoid, rounded-biconvex, 4-5mm long, drab, at length brunescent, with thickened unequal nerves, subsessile, abruptly contracted into short straight-bidentate smooth beak.

Taxonomic remark Is known only from the mentioned location. From C. riparia, the latter also occurring in vicinity of the village Arslanbob, differs by broad-ovoid utricles with thickened veins (C. riparia has oblong-ovoid or ovoid utricles with thin veins). Kreczetowicz (1935) considered C. anisoneura as an unclear species and suggested that the plants belonging to it are a form of C. riparia. The species needs further investigation. [details]
