About Agrostis vinealis Schreb.
Agrostis vinealis Schreb. is a perennial, caespitose grass with elongated rhizomes. The whole plant grows 30–60 centimetres (12–24 in) tall and 1 millimetre (0.039 in) wide. Its culms are 10–60 centimetres (3.9–23.6 in) long and erect. It has an eciliate membrane ligule that is 1–5 millimetres (0.039–0.197 in) long and obtuse. Its leaf-blades are flat and scabrous, measuring 2–15 centimetres (0.79–5.91 in) long by 1–3 millimetres (0.039–0.118 in) wide. The plant produces an open, lanceolate reddish-purple panicle inflorescence that is 2–20 centimetres (0.79–7.87 in) long. Spikelets are solitary, each holding one fertile floret with a pubescent callus. The elliptic spikelets themselves are 2–3.3 millimetres (0.079–0.130 in) long and borne on filiform pedicels. The species has an oblong, keelless fertile lemma that is 1.5–2.5 millimetres (0.059–0.098 in) long; the lemma bears one awn 2–4.5 millimetres (0.079–0.177 in) long, and a 0.5 millimetre (0.020 in) long palea that is hyaline, just like the fertile lemma. Glumes match the spikelet in length, are both lanceolate and membranous, lack lateral veins, and have acute apexes. Flowers are also membranous, with two lodicules, two stigmas, and three stamens that measure 1–1.5 millimetres (0.039–0.059 in) long. Fruits are caryopses with an additional pericarp, a linear hilum, and farinosed endosperm. In terms of distribution, in Great Britain the species grows alongside birch, pine, and oak trees at elevations of 0–845 metres (0–2,772 ft) at Little Dun Fell, Westmorland, Scotland. In Iceland, it occurs on various hills and heathlands. In China, it is found in the provinces of Heilongjiang, Jilin, and Liaoning at elevations of 1,500–1,700 metres (4,900–5,600 ft). In Pakistan, it is native to the regions of Punjab, Gilgit, and Kashmir, where it grows at elevations of 2,300–4,300 metres (7,500–14,100 ft).
