The results of the comparative-morphological analysis of Typha astrakhanica are presented. It has been established that according to morphological signs, plants from the southern reservoirs (Volga delta) of the Astrakhan oblast differ from those given in the botanical literature, T. angustifolia, T. australis, T. domingensis, T. grossheimii. The described species has membranous, rounded at the apex upward-directed lobes (ears) of the vagina of stem leaves, narrowly lanceolate, breaking off stigmas of fruiting flowers, It is assumed that T. astrakhanica is a Paleogene species of Kamyshin flora [Akhmetyev, 2007].
