Chrysosplenium wrightii

Chrysosplenium wrightii, or Wright's golden saxifrage, is a plant species native to northwestern North America and northeastern Asia. It grows on tundra and along stream banks at elevations up to 2300 m in British Columbia, Yukon, Alaska, the Kamchatka Peninsula in Russia, and in eastern Siberia. The plant was first described in 1878 as being from Japan. This was based on material collected along the Sea of Okhotsk presumably either Sakhalin Island or one of the Kuril Islands, parts of Japan at the time but now in the Russian Federation.[2][3][4]
