Kurrajong cites Fire Resistant and Retardant Plants as its selected laboratory lineage. Brachychiton populneus remains on-list on the evidence table. One ecological invasive report is tracked outside that fire tally, with its geographic material available under range evidence.
The related plants section offers cited comparisons without treating the ecological report as another fire vote. The existing genus page keeps other records separate within that genus. Together, those paths preserve the selected lab citation, the on-list result, and the ecological evidence as answers to their own questions on this species page.

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.
Native and introduced range evidence
These are exact U.S. botanical-area records from the cited range source. Native and
introduced describe biogeographic relationship, not fire performance or planting approval.
Doubtful and extinct rows stay visible but do not count as current presence.
The lossless worldwide derivative is retained once in the research corpus; object pages repeat only exact U.S. areas needed by the local lens. The JSON twin carries the same page assertions.
Where its sources say to plant it
Placement rules below use each source's own distances or named zones, tied to its rating.
They are not interchangeable with the directory's current Zone 0 guidance.

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.
22 cited rows from this source; its identity, lineage and tier are stated once.
