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.
Distribution:
Found in the southern part in South Australia, growing on banks and along streams in moist areas. Also found in Western Australia, New South Wales, Victoria and Tasmania.
Status:
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 curved 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.
