About Ceará Rubber Tree
Ceará Rubber Tree (Manihot glaziovii) 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 to seasonally dry northeastern Brazil and formerly planted in tropical regions as a rubber source. Its deciduous tendency and thickened, latex-bearing stems suit seasonal moisture regimes. Bishop Museum documents naturalized Kauaʻi occurrence, while current abundance, occupied habitat, and ecological effects remain unassessed.
