Reproductive biology of the Permian Glossopteridales and their suggested relationship to flowering plants.

The discovery of permineralized glossopterid reproduction organs from Late Permian deposits in the Beard-more Glacier region (central Transantarctic Mountains) of Antarctica provides anatomical evidence for the adaxial attachment of the seeds to the megaasporophyll in this important group of Late Pa...
