 |
Polyphlebium
venosum (bristle filmyfern) is the only member of this
genus in Tasmania. It is a common native rainforest
epiphyte. Like all filmy ferns, the leaf laminas are only
one cell thick, but in this species the lobes are
multi-veined. The sporangia are in a cylindrical tube with a
protruding, hair-like structure.
