Abstract

Charophytes are described and illustrated from the Upper Devonian of Western Australia, including five genera and nine species of which four are new species. Most belong to the Family Umbellinaceae being placed in a new Class Umbellinaphyceae of the Division Charophyta. Representatives of these genera occur in Devonian sediments of Europe, Asia, North America, and Australia. A species of Sycidium described by Karpinsky (1906) as Sycidium panderi is also identified from Western Australia.
