形态特征（Description）：根状茎粗壮，木质，具匍匐茎。秆疏丛生，侧生，纤细，高25-35厘米，粗2-2.5毫米，下部光滑，上部疏被短柔毛，三棱形，基部具褐色的叶鞘。叶基生和秆生；基生叶单1生于根状茎的节上；叶片椭圆形或椭圆状披针形，长20-42厘米，宽4-10厘米，下面粗糙，上面平滑，具7-14条脉，其中有3条脉明显隆起，呈折扇状，基部渐狭，全缘，顶端尾状渐尖；叶柄长7-10厘米，对折，边缘反卷，无毛；秆生叶退化呈佛焰苞状，绿色，具条棱，疏被短柔毛，边缘褐色，膜质。苞片佛焰苞状，与秆生叶近同型。圆锥花序复出，具数个支花序；支花序单生或双生，总状，通常具1-2 (3) 个小穗；支花序柄纤细，基部的1个长达8厘米，向上的渐短，粗糙；小苞片鳞片状，卵状披针形，长3-4毫米，疏被毛。小穗从囊状、内无花的支先出叶中生出，线状圆柱形，长2.5-4厘米，粗3-4毫米，两性，雄雌顺序；雄花部分轮廓为长圆形，与雌花部分近于等长；雌花部分具多数疏生的花。雄花鳞片长圆形，长4.5-5毫米，顶端钝圆，膜质，深褐色，具3条脉；雌花鳞片长圆形，长4.5-5毫米，顶端渐尖，膜质，淡褐色有深褐色斑点和短线，背面疏被短粗毛，有3条脉。果囊椭圆形，三棱形，长约4毫米，淡褐色，膜质，有深褐色斑点和短线，腹面具2侧脉，基部几无柄，顶端收缩成中等长的喙，喙口斜截形。小坚果倒卵状长圆形，三棱形，长约2.5毫米，成熟时褐色；花柱基部不膨大，柱头3个。花果期3月。
分布（Distribution）：产于云南东南部；生于山谷湿润草地，海拔1250米。越南北部也有分布。模式标本采自越南北部。

棕叶薹草 zong ye tai cao
Rhizome thick, woody, with stolons. Culms loosely tufted, lateral, slender, 22-35 × 0.2-0.25 cm, trigonous, lower part smooth, upper part loosely pubescent, base with brown sheaths. Leaves basal and cauline; basal leaf single, elliptic or elliptic-lanceolate, 22-42 × 4-10 cm, scabrid abaxially, glabrous adaxially, 7-14-veined, replicate, entire, base attenuate, apex caudate; petiole 7-10 cm, folded, glabrous; cauline leaves green, spathelike, loosely pubescent, margins brown, membranous. Involucral bracts spathelike. Panicle compound, several branched; inflorescence branches racemose, single or binate, often 1 or 2(or 3)-spiked; peduncles of inflorescence branches tenuous, lowest one up to 8 cm, upper ones gradually shorter, scabrid; bractlets glumelike, ovate-lanceolate, 3-4 mm, loosely hairy. Spikes bisexual, androgynous, arising from flowerless utriculiform cladoprophylls, linear-cylindric, 25-40 × 3-4 mm; male part of spike nearly as long as female part, oblong; female part loosely many flowered; male glumes dark brown, oblong, 4.5-5 mm, membranous, 3-veined, apex obtuse; female glumes pale brown with dark brown spots and short lines, oblong, 4.5-5 mm, membranous, loosely hairy abaxially, 3-veined, apex acuminate. Utricles pale brown with dark brown spots and short lines, elliptic, trigonous, ca. 4 mm, membranous, with 2 lateral veins abaxially, subsessile, apex contracted into beak of medium length, orifice obliquely truncate. Nutlets brown at maturity, obovate-oblong, trigonous, ca. 2.5 mm; style base not thickened; stigmas 3.
Wet grasslands in valleys; ca. 1300 m. SE Yunnan [Vietnam].
