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

Carnivorous Plants of Australia Carnivorous Plants of Australia is a three-volume work on carnivorous plants by Allen Lowrie. The three tomes were published in 1987, 1989, and 1998, by University of Western Australia Press. An entirely updated three-volume work by Lowrie was published by Redfern Natural History Productions in December 2013 as Carnivorous Plants of Australia Magnum Opus. The first volume deals exclusively with tuberous sundews (genus "Drosera"). The second is devoted
