The genus index supplies another comparison path without changing the recommendation or source depth. For melanocaulon, the accepted rows establish the avoid direction; the alternative set keeps its separate browsing role. Returning to the evidence table preserves that division and does not import support from another willowherb. The limited-depth notice continues to describe only this record's pack. The cited alternatives do not replace the willowherb recommendation.

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.
