Pyrrosia platyphylla
Description
Stellate hairs dimorphic, a dense mat, greyish brown, the straight upper rays appressed, narrowly boat-shaped to acicular.
Taxonomy
Has been confused with P. costata, from Continental Asia. Pyrrosia platyphylla differs most strikingly in the costa being triangular in cross section, not quadrangular as in true P. costata. It can be confused also with P. princeps, which has a shorter rhizome, with the phyllopods contiguous.
