About Manyleaf Senna
Manyleaf Senna (Senna multijuga) is an introduced tree documented as naturalized on Kauaʻi by Bishop Museum’s 2025 checklist. Native from Mexico through tropical South America and associated with wet tropical forest edges and disturbed vegetation. Abundant flowers and numerous pod seeds support colonization. Bishop Museum documents the Kauaʻi record under Senna multijuga var. multijuga and normalizes it to the accepted species concept; Smithsonian screening did not return an exact match.
