Appearance
Mountain sorrel is a perennial plant with a tough taproot that grows to a height of 10 to 30 cm . It grows in dense tufts, with stems that are usually unbranched and hairless. Both flowering stems and leaf stalks are somewhat reddish. The leaves are kidney-shaped, somewhat fleshy, on stalks from the basal part of the stem. Flowers are small, green and later reddish, and are grouped in an open upright cluster. The fruit is a small nut, encircled by a broad wing which finally turns red. Forming dense, red tufts, the plant is easily recognized. ''Oxyria digyna'' grows in wet places protected by snow in winter. ''Oxyria'' means "sour".Distribution
Mountain sorrel is common in the tundra of the Arctic. Further south, it has a circumboreal distribution, growing in high mountainous areas in the Northern Hemisphere such as the Alps, the Sierra Nevada, and the Cascade Range. It typically grows in alpine meadows, scree, snow-bed sites and beside streams.On the coast of Norway, the pollen of this plant has been found in peat bogs that are 12,600 years old, indicating that it must have been one of the first plants to colonise the area after the retreating ice age glaciers.

Uses
The leaves of mountain sorrel have a fresh acidic taste and are rich in vitamin C, containing about 36 mg/100g. They were used by the Inuit to prevent and cure scurvy, and can be used in salads. It is called ''qunguliq'' in Inuktitut. The above-ground parts of the plant are edible when cooked . The plant is important for both insects an larger animals that feed on it in arctic and alpine regions where it occurs.References:
