Open this record in the interactive AtlasAbout Glaucous Senna
Glaucous Senna (Senna surattensis) is an introduced tree documented on Kauaʻi by Bishop Museum’s 2025 checklist and the 2026 Smithsonian checklist. Its checklist classification is naturalized; current extent is unassessed. Native from tropical and subtropical Asia through parts of Malesia and the Pacific and associated with open woodland, savanna, and disturbed vegetation. Repeated pod production supports persistence. Bishop Museum and Smithsonian document naturalized Kauaʻi occurrence; current abundance and effects are unmeasured.

- Reproduction
- Yellow flowers require pollination and mature into dry many-seeded pods. Seeds fall locally or move with water, animals, and disturbed soil; local pollinators, dormancy, and recruitment are unknown.
