Rissikia and mataia podocarpaceous conifers from lowermesozoic of southern lands

Abstract

The genus Rissikia gen. nov. consisting of leafy shoots and detached pollen and seed cones is described, with two species, R. media (Tenison Woods) com. nov. and R. apiculata sp. nov. Also described is Mataia gen. nov. with one species M. podocarpoides (Ettinghausen) com. nov. These are all ascribed to the Podocarpaceae, and the evolution of the Family, particularly of the epimatium is discussed.
