Гінкгавыя (Ginkgoopsida)[3]
Гінкгавыя — кляса голанасенных расьлінаў, які зьмяшчае адзіны сучасны від — гінкга двухлопасьцевы (Ginkgo biloba).
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 monophyly of this group as a whole has been considered questionable by other authors.[4] Other authors have used the class as a monotypic grouping, including only Ginkgoales.[5]
