Pentarhizidium is a genus of two Asian fern species. These species have formerly been included in Matteuccia or Onoclea.^[1] Recent genetic analysis has determined that these two species form a discrete clade that is basal to the rest of this fern group, and so have been located in their own genus. P. orientale is sometimes grown as a garden plant.
