Abstract: The herbaceous lycopsid Drepanophycus minor sp. nov. is described from the late Mid Devonian Hujiersite Formation of Xinjiang, Northwest China. The new species is characterized by minor sized, falcate microphylls, and kidney-shaped sporangia, with rhizome, K-shaped branching, and developed lateral buds. Stomatal apparatuses are observed from the axis surface of the new species. The habit and the rhizome structure of D. minor are discussed.

Key words: Devonian, Drepanophycus, Hujiersite, lycopsid, Xinjiang.
