Cheilanthes austrotenuifolia enters through the fire-resistant plant citation, its selected source lineage. The evidence table marks the support as limited evidence. From its accepted row, the direction is on-list.

The related plants section provides comparison for this rock fern. Its genus page offers broader navigation for Cheilanthes, without importing another species' evidence. That visible separation ties the plant-list citation, limited support, and computed result to austrotenuifolia; the evidence table remains the direct path to the accepted basis. This rock-fern entry alone carries that combination of citation and direction under the named species boundary.

How to read this page

The status above is computed from the cited rows below: independent recommendations can support a fire-resistant result, an avoid row can produce keep-away, and disagreement stays visible as conflict. Placement notes preserve each source’s own scheme rather than translating unlike rules into one scale. This is evidence about a plant, not permission to plant it in every part of the defensible space; Zone 0 remains noncombustible.

The evidence

Grouped by what each source concluded. Primary evidence rated the plant itself (a lab, field program, or original curation); corroboration compiled or republished another source's rating and resolves to its root lineage.
