Abstract
Leaf fragments with an epidermal structure confidently suggesting their affinity to the genus Phoenicopsis Heer (Czekanowskiales) have been discovered for the first time in the Jurassic of Mangyshlak (Kazakhstan). Representatives of this genus were previously identified n this flora based on the morphological characters of the leaf compressions only. Two new species of the subgenus Phoenicopsis are described, P. insolita N. Nosova et Kiritch., sp. nov. and P. sauranica N. Nosova et Kiritch., sp. nov., as well as a species of the subgenus Culgoweria, P. tanynbaica N. Nosova et Kiritch., sp. nov. The stomatal topography of P. kilpperiana (Schweitzer et Kirchner) Kiritch. has been re-examined in greater detail on the basis of the available type material from the Early Jurassic of Iran.
