Ginkgoopsida is a proposed class of gymnosperms defined by Sergei V. Meyen in 1984 to encompass Ginkgoales (which contains the living Ginkgo) alongside a number of extinct seed plant groups, which he considered to be closely related based on similarities of morphology of pollen, seeds, cuticles, short shoots and leaves.[1][2][3] The validity of this group as a whole has been considered questionable by other authors, who consider that it is unlikely to be monophyletic.[4] Other authors have used the class as a monotypic grouping, including only Ginkgoales.[5] Some authors have used the clade Ginkgophyta to encompass both Ginkgoales and Czekanowskiales/Leptostrobales, are suggested to be closely related groups.[6]
