Insect resources, birds and habitat
Bars show recorded counts on a linear scale. Each category runs from zero to its largest count in this NC plant catalog; the same scale applies across plant pages. Compare plants within a category, not bar lengths across categories. Zero records may mean missing research. Growth form is shown as text.
Additional insect evidence
Bar length follows recorded-name count on the displayed scale, not ecological importance. Unknown is not zero support. Flower visits do not confirm feeding or pollination. Named insects may include historical or unresolved names.
Provisional additional insect credit: +0 (maximum 5). Scoring rule and limitations. Study references and interaction records are included in this plant’s data record.
