Abstract

The results of a comparative morphological analysis of Typha sakhalinica Krasnova et Efremov are pre-sented. It was found that the morphological characters of the reproductive organs do not correspond to T. latifolia from the European part of Russia. The species is distinguished by staminate flowers with narrow membran-ous anthers, large and solitary pollen, degraded flowers in bunches of three. Plants are smaller, cauline leaves with axils and membranous auricles directed downwards. It is believed T. sakhalinica is a Pleistocene species that emerged from the isolation of Sakhalin Island from the mainland North-Eastern Asia.
