Dactylorhiza sambucina (Orchidaceae) should be excluded from the Flora of Russia; [Обоснование исключения вида Dactylorhiza sambucina (Orchidaceae) из состава флоры России]

Ihe species Dactylorhiza sambucina, which is included into the Red Data Book of Russian Federation, should be excluded from the Flora of Russia. Its reports from the Orel Region were based on the incorrectly determined herbarium specimens of other taxa. Reports from the Bryansk Region although not confirmed by herbarium specimens are also obviously erroneous as evidenced by their collection date. Reports from the Republic of Chuvashia were already earlier acknowledged as incorrect by Margarita Gafurova in the "Flora of Chuvashia". © 2022 Altai State University. All rights reserved.
