Translation Plant cespitose and shortly stoloniferous, with thick woody stolons. Lateral culms somewhat scapiform, 30–60 cm tall, slender (1–2 mm thick), obtusely or obscurely trigonous, apparently suberect, striate, densely pubescent above. Cauline leaves (including the bracts) sheath-like, 7–9, somewhat herbaceous, loosely sheathing, narrowly funnel-shaped, densely and mostly appressed-hispidulous-pubescent, the mouth broadly ferrugineous-hyaline, separated by regular intervals (the lowermost somewhat crowded), all subequal, 3–6 cm long, abruptly passing into a short blade. Sterile leaves produced in fascicles of 2–3 and forming a strong tussock, surrounded by a few large, long, bladeless sheaths, withered but entire; blades elliptic-oblanceolate, long-acuminate above, decurrent into a nearly equally long robust pseudo-trigonous petiole (with recurved margins), narrowly but deeply channelled; including the petiole 53–98 cm long, 4–6.7 cm wide, apparently arcuate, flat, somewhat coriaceous, non-sheathing, far exceeding the inflorescence; many-nerved, but with the midrib and two lateral nerves stronger and more prominent, these equidistant from the midrib and margins and prominently keeled together with the finer nerves; the midrib keeled only on the lower surface, flat or narrowly channelled above; surfaces smooth above (except scabrous towards the apex), beneath all nerves appressed-hispidulous. Inflorescence a simple panicle, 14–39 cm long; branches 4–6, more or less pyramidal, each bearing 4–7 spikes, with long or very long slender peduncles densely pubescent and exserted from the bracts. Androgynous spikes, lateral ones somewhat spreading at anthesis, fruiting ones spreading, 7–13 mm long, few-flowered, female part sometimes absent, male part slightly longer than the female part, arising from sterile utriculiform branch cladoprophylls, sessile or the lower ones sometimes shortly pedunculate. Bracteoles scale-like, oblong-lanceolate or oblong-ovate, glabrous inside, sparsely hispidulous on the back and densely so on the margins, shortly scaberulous-awned. Female scales about 3.5–4.5 mm long, about 1.5–2 mm wide, oblong-ovate, oblong-lanceolate, or ovate-lanceolate, sometimes acuminate, apex acute or obtuse, margins erose at and near the apex, glabrous inside, dorsally hirtellous and appressed-hispidulous on sides and margins, chestnut-colored except for the paler three-nerved median band marked with reddish dots; midrib finely keeled, usually shortly excurrent into a scaberulous tip. Male scales about 4.5–5.5 mm long, about 1–1.75 mm wide, oblong or oblong-elliptic, more or less cymbiform, sometimes acuminate, apex acute or obtuse, thinly membranaceous, margins somewhat erose, usually glabrous on both surfaces, pale chestnut on the sides, paler in the middle and marked with reddish dots, midrib usually excurrent into a short scaberulous awn. Utricles usually clearly longer and somewhat wider than the scales, about 5 mm long and 1.75–2 mm wide, trigonous, elliptic-lanceolate, at first somewhat erect, later spreading to somewhat reflexed, glabrous, smooth, angular on the ventral (adaxial) face, strongly about 9-nerved, dorsal (abaxial) face flat to slightly concave, finely or obscurely 4–5-nerved, chestnut-brown, spongy at the base but scarcely stipitate, rather abruptly contracted into a 1.5–2 mm long subterete, straight, glabrous, unwinged beak with an obliquely cut mouth and erose-truncate apex. Nut tightly enclosed, elliptic, triquetrous, with prominent angles and somewhat concave faces, narrowed at the base into a very short thickish stipe, apex slightly rounded and scarcely beaked, brownish-straw-colored. Style slightly thickened at the base. Stigmas 3. [details]
