''Chrysosplenium wrightii'', the Bering Sea Water-carpet, 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 "Ochotsk Sea," presumably either Sakhalin Island or one of the Kuril Islands, parts of Japan at the time but now in the Russian Federation.〔〔(Franchet, Adrien René & Savatier, Paul Amedée Ludovic. 1878. Enumeratio Plantarum in Japonia Sponte Crescentium 2(2): 356 ).〕〔Suto, Tiharu. 1935. Journal of Japanese Botany 11(6): 396.〕 Two infraspecific taxa have been proposed, both names accepted by (The Plant List ): *''Chrysosplenium wrightii'' var. ''beringanum'' (Rose) H.Hara, from St. Paul Island in Alaska〔Hara, Hiroshi. Journal of the Faculty of Science: University of Tokyo, Section 3, Botany 7: 63. 1957.〕〔(Rose, Joseph Nelson. 1897. Botanical Gazette 23: 275. )〕 *''Chrysosplenium wrightii'' subsp. ''saxatile'' (Khokhr.) Vorosch., from Russia〔Voroschilov, Vladimir Nikolaevich. 1991. Byulleten' Moskovskogo Obshchestva Ispytatelei Prirody, Otdel Biologicheskii n.s., 96: 133.〕〔Khokhrjakov, Andrej Pavlovich. 1973. Byull. Glavn. Bot. Sada 88: 45.〕 ''Chrysosplenium wrightii'' is an herb reproducing by means of stolons running along the surface of the ground. Flowering stalks are up to 16 cm tall, bearing a cyme of up to 30 flowers. Flowers are yellow, purple, or orange, usually with purple spots. 〔(Flora of North America v 8 p 75. )〕〔Cody, W. J. 1996.
