Sphagnum such gemmae. Peat moss can be distinguished from other moss species by its unique branch clusters. The plant and stem color, the shape of the branch and stem leaves, and the shape of the green cells are all characteristics used to identify peat moss to species. "Sphagnum" taxonomy has been very contentious since the early 1900s; most species require microscopic dissection to be identified. In the field, most "Sphagnum" species can be identified to one of four major sections of the genus—classification and descriptions follow Andrus 2007 (Flora North America): The reciprocal monophyly of these sections and two other minor
Leningrad Nuclear Power Plant Leningrad Nuclear Power Plant Leningrad Nuclear Power Plant ( ()) is a nuclear power plant located in the town of Sosnovy Bor in Russia's Leningrad Oblast, on the southern shore of the Gulf of Finland, some to the west of the city centre of Saint Petersburg. It consists of four nuclear reactors of the RBMK-1000 type. These reactors are similar to reactors No. 1 and 2 of the Chernobyl Nuclear Power Plant. Two units of the VVER-1200 type are under construction at Power Plant II to replace the current RBMK reactors when they reach the end of their service lives.
