Abstract

Small plant fragments previously attributed to Dimeripteris cornuta SCHWEITZER and CAI and new specimens are described from the Middle Devonian (Givetian) Xichong Formation of Wuding, Yunnan Province, southwest China. A predominantly trifurcate branching pattern is recognized in lower orders of branching. Erect fusiform sporangia are borne in pairs terminally on a short pedicel on up to three times dichotomously-branching fertile unit. The beaked tips of the paired sporangia point outwards. This plant is distinguished from known plants by the trifurcate branching pattern and sporangia morphology, but is of problematic affinity. The plant is named Tauritheca cornuta (SCHWEITZER and CAI) WANG and BERRY nov. gen. and nov. comb.
