Extinct genus of Devonian plants From Wikipedia, the free encyclopedia
Sciadophyton is a morphotaxon of lower Devonian plants known only from compression fossils.[2][3] It is interpreted as the monoicous gametophyte of a vascular land plant, because its vascularised branches end in a cup-shaped structure bearing gametangia, both antheridia and archegonia,[4] but little structural information is preserved at the cellular level. It formed rosettes of stems, which may have radiated from a basal gametophytic corm-like thallus or from a central 'stem' or even from a root system, although there is not enough evidence to discriminate between these possibilities.[3]
