Pyrrosia tricuspis
is an evergreen perennial fern plant with approximately 4mm long
rhizomes growing on rocks or trunks. Leaves, measuring 5-15cm long
and 3.5-12cm wide, are split into three leaflets in the shape of a
hastate. Sporangia run in rows along each vein on the bottom side of
the leaves. When dried up or in wintertime, the leaves wrap
themselves inside.
