In a paper published in National Science Review, a Chinese group of palaeobotanists described a new genus and species of Late Devonian ovule (seed before fertilization), Guazia dongzhiensis gen. et sp. nov., which is borne terminally and has folded, wing-like integumentary lobes but no cupule. G. dongzhiensis presents evidence for Devonian acupulate ovules (ovules without a cupule) and specialized integuments adapted to wind dispersal.
