Physematium is a small genus of ferns in the family Woodsiaceae, long treated as part of Woodsia and only recognised as distinct after a 2020 molecular study. Its members are small rock-dwelling ferns, and they are rarely grown in gardens, so care advice is generalised from related woodsias.
Physematium is a genus of ferns in the family Woodsiaceae. It was treated as a synonym of Woodsia until 2020 when a molecular phylogenetic study showed its distinctiveness. As of June 2023, Plants of the World Online continued to treat the genus as a synonym of Woodsia.
