Folia sessilia vel brevipetiolata, laminis oblanceolatis vel obovatis; marginibus undulatis vel crispatis; folia inferiora et basalia 2.2-8 cm longa, 0.8-1.4 (-2) cm lata, supra pilis minute pustulosis canescentia, subtus pilis cinereis dense villoso-tomentosa. Inflorescentia spica composita laxa in pudunculo¹ longo ex spicula terminali et 5-9 paribus spicularum lateralium constans, saepe spiculis quatour² in quoque nodo. Spiculae separatae vel densae floribus in spiram 3-seriatam dispositis. Bracteolae 2.4-4 mm longae, interiores exterioribus parum longiores, distaliter glabrae, stramineae vel atrae. Flores 3.5-5.5 mm longi. Stamina in tubum largum connata, lobis interstaminalibus terminalibus 0.5-0.9 mm longis, partem connatam perigonii non superantibus, obtusis, brunneolis vel atris, distaliter non recurvatis. Perigonium fructiferum 3-3.8 mm latum, conicum, fere latum quam longum, lateraliter anguste alatum, alis integris vel crenulatis, superficie perigonii indurati nuda.

Translation
Perennial herb 0.20-0.6(-1.1) m tall from a woody taproot. Stems thick, multiple, branched from the base, prostrate to ascending to erect, often forming mats, grayish white tomentose. Leaves sessile or short-petioled, with blades oblanceolate to obovate, with margins undulate to crisped; the lower and basal leaves 2.2-8 cm long, 0.8-1.4(-2) cm wide, whitish/grayish above with minutely pustulose[-based] hairs, densely villous-tomentose below with ash gray hairs. The inflorescence a lax compound spike on a long peduncle consisting of a terminal spikelet and 5-9 pairs of lateral spikelets, often with four spikelets at each node. Spikelets open to dense with flowers arranged in a 3-ranked spiral. Bracteoles 2.4-4 mm long, the inner ones slightly longer than the outer ones, distally glabrous, stramineous or black. Flowers 3.5-5.5 mm long. Stamens connate in a long tube, with terminal interstaminal lobes 0.5-0.9 mm long, not extending beyond the connate part of the perigonium, obtuse, brownish to black, not recurved distally. Fruit-bearing perigonium 3-3.8 mm wide, conical, nearly as wide as long, narrowly winged laterally, with wings entire or crenulate, with the surface of the indurate perigonium naked.
