Cheilanthes austrotenuifolia

Cheilanthes austrotenuifolia is a species of Australian rock fern from the family Pteridaceae. Once a common understory plant prior to European settlement of the Adelaide Plains in South Australia, Cheilianthes austrotenuifolia is still quite widespread in temperate rural remnant scrub, such as areas of the Adelaide Hills.

Bright green fronds grow from an underground rhizome. The plant spreads through division of this rhizome, and also by spores held under the fronds. Fronds die down in summer and return with the rain.

The plant is very difficult to propagate using spores, but it may be more easily done using sections of the rhizome.
