Calamagrostis stricta, known as slim-stem small reed grass[1] or narrow small-reed,[2] is a species of bunchgrass in the family Poaceae of the Holarctic Kingdom.

The species is perennial and caespitose with elongated rhizomes and 30–100 centimetres (12–39 in) long culms which are also erect.

The leaf-blade also have a ribbed and pubescent surface with scaberulous margins the apex of which is filiformed.

[3] The glumes are firmer than fertile lemma and are elliptic, membranous, with acute apexes and asperulous surfaces.

[3] Calamagrostis stricta is found in wetlands throughout Eurasia (including Siberia) and into Mongolia and China.
