Oxyria

a genus of plants of the Polygonaceae (buckwheat) family. They are perennial herbs with a creeping rhizome and radical kidney-shaped leaves on long petioles. The flowers are bisexual and in a panicle. The perianth is tetramerous; there are six stamens; the fruit is a pinnate nutlet. Two or three species are known in Eurasia and North America; they grow in the arctic zone and in the alpine belt of mountains, near brooks and springs, on shingle, and on rocky slopes. In the USSR mountain sorrel (O. digyna) grows in the tundra and mountains of Siberia and the Far East, while O. elatior grows in the Caucasus and Middle Asia. Oxyria leaves are acid to the taste and rich in vitamin C.

For example, despite Geum reptans and Oxyria digyna being dormant (Table 1), they were both short-term persistent corroborating the claim that some dormant seeds are also short-lived in soil.

One of the most common dishes in this area is a sort of mixture of Chukchi cabbage with a small quantity of coltsfoot (Tussilago farfara) and other bitter plants, such as mountain sorrel (Oxyria digyna), Arctic sorrel (Rumex arcticus), and Nelson's saxifrage (Saxifraga nelsoniana), to which seal fat and caviar is added, and the mixture is then left to ferment.

In order to determine whether the differences between treatments (warm/control) and habitat types observed in the previous experiment are due to phenotypic plasticity or evolutionary adaptation, I performed a reciprocal transplant experiment with three species that are abundant in the ITEX plots (forbs Oxyria digyna and Papaver radica-tum, and grass Arctagrostis latif blia).
