清涼峰薹草(qīng liáng fēng tái cǎo)，學名:Carex qingliangensis D. M. Weng, H. W. Zhang & S. F. Xu，是單子葉植物綱莎草科薹草屬的植物]]，Rhizome short, indurate. Culms tufted, 40-55 cm tall, slender, trigonous, smooth, covered at base by dark brown bladeless sheaths. Leaves shorter or longer than culm, blades 4-7 mm wide, flat, trabeculate, scabrid along distal margins. Involucral bracts setaceous, shorter than subtending spikes, sheath 0.5-2 cm. [1]
形態特徵
Rhizome short, indurate. Culms tufted, 40-55 cm tall, slender, trigonous, smooth, covered at base by dark brown bladeless sheaths. Leaves shorter or longer than culm, blades 4-7 mm wide, flat, trabeculate, scabrid along distal margins.
Involucral bracts setaceous, shorter than subtending spikes, sheath 0.5-2 cm. Spikes 4 or 5; terminal spike male, cylindric, clavate, 25-45 mm, with peduncle 1-2.5 cm; lateral spikes female, rather widely spaced, linear-cylindric, 25-40 mm, densely flowered, peduncle 1-2.5 cm, barely exserted from bract sheath.
Female glumes pale green, elliptic-ovate, 3.5-4 mm, costa yellow-green, with a distinct midrib, apex acuminate with a short scabrous awn. Utricles green, slightly longer than glume, oblong-ellipsoid, trigonous, 4-5 mm, sparsely pubescent distally, prominently many veined, base attenuate, not stipitate, apex with a straight beak ca. 1.5 mm, orifice distinctly emarginate.
Nutlet ashy brown, tightly enveloped, oblong-ovoid, 2.5-3 mm, faces concave in proximal half, angles not constricted at middle, base with a short straight stipe, apex gradually contracted into a short cylindric beak; style base slightly thickened; stigmas 3. Fl. and fr. Apr-May.

薹草屬介紹
薹草屬多是多年生草本植物，一些種是一年生的。有些薹草屬像草坪一樣生長非常密集，也有些長的或短的匍匐生長。它們往往有非常茂密多分支的根莖，有些也成群簇生。莖無節，一般多少呈三角形，下部在楞處往往有粗糙的齒。葉細長，端部是尖的，有時會非常鋒利。
薹草屬一般是雌雄同體的，少數是雌雄異株的。其中不同的種可以分為是單穗的（莖末單穗）、雌花雄花位於同一穗或同一花絮上的（雌花和雄花的形狀一樣）以及多穗的（雌花串狀，雄花穗狀）。有些種類的雌花與雄花交雜在同一穗上，有些是分開的。種子被殼完全包圍，但是沒有像禾本科植物那樣與殼長到一起。
薹草屬植物生長在泥濘、酸質的草地上。牲畜不能吃它們（因為酸性太高）。它們也可以像蘆葦那樣生長在淺水中。一些根比較密集的薹草屬被用來種在沼澤地上或沙地的斜坡上來穩固這樣的斜坡（比如壩或者公路邊的斜坡）。[2]
