If you've ever visited a temperate rainforest in B.C.—on the coast or in the interior—you may have marveled at all of the ferns. The term Pteridophyte is derived from two words 'Pteron' meaning feather and 'phyton' meaning plant. In contrast, pteridophytes constituted the most important vascular plant group on rocks, where 64 species were found, forming about two‐thirds of the vegetation cover. The contributors discuss conceptual issues, showing the importance of sex allocation, sexual selection and inclusive fitness, and the dimensions of paternity and maternity in plants.
