Nardus is a genus of plants belonging to the grass family.[5]

The name derives from the Nardos (ναρδοσ), the ancient Greek name for this plant. It is not to be confused with Spikenard, Nardostachys grandiflora.

Species

The only recognized species is matgrass, Nardus stricta.[6] It is native to Eurasia (from Iceland and the Azores to Mongolia), North Africa (Algeria, Morocco), and northeastern North America (Greenland, eastern Canada, and the northeastern United States).[3][7]

Habitat[edit]

Nardus stricta occurs on heath, moorland, hills, and mountains on nutrient poor acidic sandy to peaty soils and is strongly calcifuge, avoiding calcareous soils. It can occur from low elevations to over 1,000 metres (3,300 ft), becoming a community dominant in late snow patches on mountains. Nardus stricta may also become a dominant species in habitats grazed by cattle or sheep because it is tough and unpalatable.[8] [9]


Description[edit]

Culms are erect and 25–60 centimetres (9.8–23.6 in) long, with grey-green leaf-blades filiform and involute, ranging from 4–30 centimetres (1.6–11.8 in) long by 0.5–1 millimetre (0.020–0.039 in) wide, i.e. bristle like. The ligules of basal leaves are 0.4–0.8 millimetres (0.016–0.031 in) long and blunt, while those of culm leaves are longer, up to 2 millimetres (0.079 in), and more pointed..[10]

The roots and shoots are very closely packed together at the base of the plant producing a white, tough, highly reflective feature.

The spikelets are very slender and loosely overlapping in two rows each side of the spikelet axis. Each lemma is tipped with an awn.

It flowers from June until August. Apomixis is found to be common in this plant with whole extensive colonies covering large areas proving to be a single clone. [11]
