Ferns and Fern Allies in the Canberra Region
Microsorum diversifolium - Kangaroo Fern
Microsorum diversifolium is locally common in the Canberra region.
It prefers sunny spots, covering the tops and flanks of large granite
boulders, for example in the higher reaches of ferny creeks in the Tidbinbilla
Nature Reserve. It scrambles thickly over the sides of the boulders
with the rhizomes sometimes hanging down to the creek.

divided with two or more branches, but some grow as single "straps"
and resemble Blechnum patersonii from a distance. The species
that grows wild in the A.C.T. has somewhat softer and thinner fronds
than specimens found elsewhere, resembling Microsorum scandens
(Fragrant Fern), also found in the region.

The spore casings are set into an indentation in the underside of the
pinna, which shows as a bump on the upper side of the frond.
