About White siris
White siris (Albizia procera) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native across tropical and subtropical Asia to Queensland, in wet tropical, moist deciduous, semi-evergreen, monsoon and gallery forests. Insect-pollinated flower heads mature into flat pods; hard seeds germinate after scarification and suitable moisture, and the tree forms nitrogen-fixing root nodules.
Kauaʻi evidence
Taxonomic identity, tree form, diagnostic morphology and island occurrence use the linked reviewed sources. Historical planting, cultivation, naturalization and invasive status are separate. Generated imagery is not occurrence evidence. The 1918–1959 Kauaʻi reforestation working register records 50 plants under Albizia procera across 2 entries dated 1927. These are recorded planting quantities, not counts of surviving trees, and they do not by themselves establish current persistence, naturalization, or ecological impact.
