Carex bostrychostigma

Carex bostrychostigma, also known as curled-stigma sedge, is a sedge that is found in eastern Russia, eastern and central China, Korea and parts of Japan.

Description

The sedge is ligneous with an elongated rhizome. The sheaths that cover the rhizome fall apart into dark brown fibres. It is composed of densely tufted slender, smooth and trigonous culms which are in length. The leaves are usually shorter than the culms and have flat and scabrous wide blades.

Distribution

The sedge grows in temperature biomes and is found in far eastern parts of Russia in eastern Amur and the Primorye regions. In China the native range is in eastern parts including Manchuria and northern parts of Central China. It is also a native of Korea and Japan.

Taxonomy

The species was first described by Karl Maximovich in 1886 in the Bulletin de l'Académie impériale des sciences de St.-Pétersbourg.
