异名（Synonym）：Carex siderosticta var. variegata Akiyama
科属（Family & Genus）：莎草科Cyperaceae薹草属Carex
形态特征（Description）：根状茎长。营养茎和花茎有间距（其生长方式参见汤彦承等，云南植物研究9 (3): 309, 1987) ，花茎近基部的叶鞘无叶片，淡棕褐色，营养茎的叶长圆状披针形，长10-20厘米，宽1-2.5 (3) 厘米，有时具白色条纹，中脉及2条侧脉较明显，上面无毛，下面沿脉疏生柔毛。花茎高达30厘米，苞鞘上部膨大似佛焰苞状，长2-2.5厘米，苞片长5-10毫米。小穗3-6 (10) 个，单生或孪生于各节，雄雌顺序，线状圆柱形，长1.5-3厘米，具疏生的花；小穗柄长2-6厘米，多伸出鞘外。雄花鳞片披针状长圆形，先端尖，长5-6毫米，两侧透明膜质，中间绿色，具3条脉；雌花鳞片椭圆状长圆形至披针状长圆形，先端钝，长4-5厘米，两侧透明膜质，中间绿色，具3条脉，遍生稀疏锈点。果囊倒卵形或椭圆形，三棱形，长3-4毫米，平滑，具多条明显凸起的细脉，基部渐狭，具很短的柄，先端骤狭成短喙或近无喙，喙口平截。小坚果紧包于果囊中，椭圆形，三棱形，长约2毫米；花柱宿存，基部不膨大，顶端稍伸出果囊之外，柱头3个。花果期4-5月。
分布（Distribution）：产于黑龙江、吉林、辽宁、河北、山西、陕西、山东、安徽、浙江、江西；生于针阔叶混交林或阔叶林下或林缘，海拔1000-2000米。分布于俄罗斯远东地区、朝鲜、日本。

宽叶薹草 kuan ye tai cao
Rhizome elongate. Flowering culms and vegetative culms spaced; flowering culms clothed by bladeless sheaths at base, pale brown, without leaves. Leaf blades of vegetative culms oblong-lanceolate, 10-20 × 1-2.5 cm, sometimes with white stripes, midvein and 2 lateral veins rather distinct, sometimes ciliate, glabrous adaxially, sparsely pilose on veins abaxially or on both surfaces. Flowering culms up to 30 cm tall; involucral bract sheaths inflated above and spathelike, 2-2.5 cm, with blade 5-10 mm. Spikes 3-6(-10), single or binate at each node, androgynous, or terminal spike usually male, linear-cylindric, 1.5-3 cm, loosely flowered; peduncles 2-6 cm, usually exserted. Female glumes elliptic-oblong to lanceolate-oblong, 4-5 mm, hyaline-membranous laterally, sparsely rusty punctate, green costa 3-veined, apex obtuse. Utricles obovate or elliptic, trigonous, 3-4 mm, glabrous or pilose, slenderly and prominently many veined, base attenuate into a very short stipe, apex contracted into a short beak or beakless, orifice truncate. Nutlet tightly enveloped, elliptic, trigonous, ca. 2 mm; style persistent, base not thickened, slightly exserted from utricle; stigmas 3. Fl. and fr. Apr-May.
Needle-leaved and broad-leaved mixed forests and forest margins or broad-leaved forests, rather dry grasslands; 1000-2000 m. Anhui, Hebei, Heilongjiang, Jiangsu, Jiangxi, Jilin, Liaoning, Shaanxi, Shandong, Shanxi, Zhejiang [Japan, Korea, Russia (Far East)].
