Blechnum
cartilagineum (gristle fern) is rare native
ground fern only known in Tasmania from a few creeks in
western and northern areas. It is a moderately large ground
fern. The fronds are often quite hard. The distinctive
feature is that unlike all the other Blechnum
species in Tasmania, the fertile fronds look similar to the
leaves.
