Carex

Also known as sedge, true sedges

Carex is a vast genus of over 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges; however, those of genus Carex may be called true sedges. Carex is the most species-rich genus in the family. The study of Carex is known as caricology.

AI overview

Carex is a large group of over 2,000 species of grass-like plants belonging to the sedge family, making it the most species-rich genus within that family.

模式種 Carex hirtaL. [1] 綠色部分為其分佈範圍薹草属（学名：Carex）是莎草科中的一个属，至今已知的共有约2000个种。大多数这些植物生活在寒带或者溫帶地区。特征茎的横截面薹草属多是多年生草本植物，一些种是一年生的。有些薹草属像草坪一样生长非常密集，也有些长的或短的匍匐生长。它们往往有非常茂密多分支的根茎，有些也成群簇生。茎无节，一般多少呈三角形，下部在楞处往往有粗糙的齿。叶细长，端部是尖的，有时会非常锋利。薹草属一般是雌雄同体的，少数是雌雄异株的。其中不同的种可以分为是单穗的（茎末单穗）、雌花雄花位于同一穗或同一花絮上的（雌花和雄花的形状一样）以及多穗的（雌花串状，雄花穗状）。有些种类的雌花与雄花交杂在同一穗上，有些是分开的。种子被壳完全包围，但是没有像禾本科植物那样与壳长到一起。薹草属植物生长在泥泞、酸质的草地上。牲畜不能吃它们（因为酸性太高）。它们也可以像芦苇那样生长在浅水中。一些根比较密集的薹草属被用来种在沼泽地上或沙地的斜坡上来稳固这样的斜坡（比如坝或者公路边的斜坡）。参考文献 ^ Ilkka Kukkonen; Heikki Toivonen.

==Description== All species of Carex are perennial, although some species, such as C. bebbii and C. viridula can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section.
