Evolutionary history of plants and radially symmetrical, is an integumented megasporangium surrounded by a cupule. The megasporangium bears an unopened distal extension protruding above the multilobed integument. It is suspected that the extension was involved in anemophilous pollination. "Runcaria" sheds new light on the sequence of character acquisition leading to the seed. "Runcaria" has all of the qualities of seed plants except for a solid seed coat and a system to guide the pollen to the ovule. The first spermatophytes (literally: "seed plants") – that is, the first plants to bear true seeds – are called pteridosperms: literally, "seed ferns", so called because their
International Union for the Protection of New Varieties of Plants agriculture for export is increasingly recognized as being unwise. Second, given the lack of empirical evidence to support this, it would make sense to encourage debate, exchange of knowledge and research on the impacts of UPOV type plant variety protection on farming, food, human rights and other public interest objectives. However, UPOV seems to be resisting this, for instance by keeping meetings secret, not making its documents available and [refusing farmers' organisations observer status with UPOV. A recent study by Professor Graham Dutfield exploring the role of UPOV concluded that UPOV's governance falls short in many different ways. In addition,
