The paper is devoted to the monotypic genus Kuvakospermum Naug. et Sidorov, emend. nov., which is interpreted as a highly advanced representative of peltasperms (order Peltaspermales). The collection studied includes six specimens of Kuvakospermum pedatum Naugolnykh et Sidorov, emend. nov. (four of them are practically completely preserved megasporophylls and two specimens with the seeds preserved in natural connection to reproductive organ, but with the partly or completely detached megasporophyll shield). The megasporophyll is stalked, peltate, with round to ovoid megasporophyll shield with the lobed margin bearing long linear extenuations. Adaxial surface of the megasporophyll shield bea...
