Lectotypification of Nymphaea tetragona Georgi (Nymphaeaceae)
Abstract
The article is focused on the lectotypification of Nymphaea tetragona Georgi (Nymphaeaceae). The species was described by the famous German botanist J. Georgi at the end of the XVIII century on the materials collected in Eastern Siberia. In 2014, a herbarium specimen collected by Georgi in 1772 in the upper reaches of the Angara River has been found in the herbarium of the Komarov Botanical Institute. It originates from the herbarium of P. S. Pallas (later owned by F. B. Fischer) and bears an annotation “Nymphaea tetragona sp. nova”. This is also evidenced by the existing on herbarium specimen additional label written, with great probability, by the hand of Georgi. Based on these evidences, we assume that the specimen belongs to the original material of N. tetragona. Due to the fact that no other original elements of this species are hitherto found in the largest Western European herbaria, we propose choosing our sample as the lectotype. It is represented by one leaf and two flowers, and no epitypification isrequired. The specimen is stored in the type collection of the Siberia and Far East Department of the Herbarium of Komarov Botanical Institute (LE). The image of the lectotype is provided here.
