Salix pseudopentandra (Flod.) Flod. in the Herbarium (LE) of the Komarov Botanical Institute RAS

Data on the distribution of the Salix pseudopentandra (Flod.) Flod. are given on the basis of herbarium specimens stored in the herbarium of the Komarov Botanical Institute (LE). Herbarium of higher plants of the Komarov Botanical Institute RAS (LE) was formed as a result of the merger in 1931 of the Herbaria of the Botanical Museum of the Academy of Sciences (1835–1931) and the Botanical Garden in Leningrad (1823–1931). It is one of the three largest Herbariums in the world and is the largest in Russia. Its funds contain more than 6 million specimens representing the flora of all continents, but especially the temperate zone of Eurasia. There are more than 120,000 type specimens. There are sectors: Eastern Europe (European part of Russia, Estonia, Latvia, Lithuania, Ukraine, Moldova), Caucasus (Russian Caucasus, Georgia, Armenia, Azerbaijan), Siberia and the Far East, Central Asia (Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan, Kyrgyzstan ), East and Central Asia (Mongolia, China, Korea, Japan), Common sector (North and South America, Africa, Western Europe, Southwest, South, Southeast Asia, Australia and Oceania), sector of doublets (exchange). The materials are arranged according to the Della Torre and Harms system. The collections of the LE Herbarium are constantly replenished with the collections of the scientists of the Botanical Institute during expeditions and excursions, exchange materials (doublets) from other Herbaria, as well as donations. They are of great importance in the world as sources of data for taxonomy, geography, phylogeny, morphology and protection of higher plants, and the study of plant resources. The dataset represents one of the common species for regional flora of Siberia and Russian Far East – Salix pseudopentandra (Flod.) Flod. Herbarium specimens were also collected in other regions of the Mongolia, China, North Korea. Images of herbarium specimens were taken with a Sony ILCE-7RM4 camera with a Vivitar 90 mm f / 2.5 macro lens.
