A New Lower Devonian Genus from Yunnan, with Notes on the Origgin of Leaf

Hao Shou-gang

Abstract

Abstract: A new genus and species, Eophyllophyton bellum, is described from the Posongchong Formation (Siegenian) of the Lower Devonian in Wenshan cfistrict, Yunnan, China This plant bears lateral branching laminate structures interpreted as leaves, which are believed to derive from lateral axial branching systems In addition similarly organised sporophylls are considered homologous to these leaves. In the possession of these vegetative leaves and sporophylls Eophyllophyton, is significantly more advanced than any other Siegenian taxon.

Key words: Lower Devonian, Siegenian, Leaf, Sporophyll, Lateral sporangia
