Carex alliiformis is a tussock-forming perennial sedge in the family Cyperaceae. It is native to eastern parts of Asia.[1]
The sedge has a short rhizome with long running stolons that are covered in bladeless, red to brown coloured sheaths. The loosely tufted culms are quite thick with a triangular cross-section and are usually in height. The flat green leaves are mostly longer than the culms and have a width of with two prominent lateral veins.[2]
The sedge is found in eastern parts of China including the provinces of Hubei, Hunan, Sichuan and Guizhou. It is also found in Taiwan, Vietnam and Japan[1] usually along forest margins, in forests or in open areas on the sides of mountains.[2]
