About Portia tree

Portia tree (Thespesia populnea) is indigenous in the Hawaiian Islands and recorded on Kauaʻi. Shrub or tree usually 5–10 m tall, sometimes taller, with gray shallowly fissured bark.

Kauaʻi evidence

Taxonomy, nativity, island-level occurrence, growth form, names, and source conservation assessments are documented in the 2026 census audit. Broader ecology and conservation recommendations still require claim-level source review. Generated imagery is not occurrence evidence.

Indigenous
Conservation status
Smithsonian checklist assessment: Apparently Secure; U.S. source status: No Status
Evidence date

Evidence limits
Island-level occurrence is retained; finer locality is intentionally withheld. Growth-form tags describe the taxon across its range, not a measured Kauaʻi population. Checklist source statuses are not a new legal-status determination. Current census nativity is indigenous; older accounts may describe Polynesian introduction. Cultural cultivation and transport history remain distinct from native status.
