Name derivation:
Cheilanthes from the Greek 'cheilos' meaning a lip and 'anthos' meaning a flower, alluding to the lip-like indusium (thin membrane covering the sorus). Austrotenuifolia from the Latin 'austro' meaning southern, 'tenuis' meaning tough or wiry and 'folium' meaning a leaf, referring to the southern distribution of this rock fern with stiff narrow fronds. The species was split from  Cheilanthes tenuifolia, which is found in the northern part of Australia.
Found southern  South Australia growing on banks and along streams in moist areas. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Native. Common in South Australia. Common in the other States.
Plant description:
Slow-creeping rhizomatous fern with red-brown, dark brown or black, hairy stems and fronds scattered, or a few crowded at the tip which dies back in summer and new fronds grow in autumn. 
Fruit type:
Sori (spores) on the underside margins of the fronds between the lobes, protected by the recurved margins.
Seed type:
Very fine spores.
Seed collecting:
Look under the fronds and collect ones with spores and place in a seal paper bags to prevent spores from fulling out.
Seed cleaning:
Leave fronds in the paper bag to dry. The spores will fall off naturally or give the fronds a gentle shake. Use a very fine sieve to separate any unwanted material. Be careful as the spores are very fine. Store spores in an air tight container in a cool and dry place or in a -20oC freezer.
