Family: Arecaceae

Origin, Description & Uses
Oenocarpus bataua (batua palm, kumbu, pataua palm) is native to tropical regions of the Americas, with a natural range extending from Trinidad and eastern Panama through much of northern and western South America. It is a tall, single-stemmed rainforest palm that can reach impressive heights in mature forest conditions. The species produces clusters of small, dark purple fruits that are traditionally valued for their edible pulp and oil-rich seeds. In its native range, it is used for food, beverage preparation (including palm fruit drinks), and local medicinal and cultural purposes. The palm is also occasionally utilized for its durable stems and other plant materials.

Risks & Threats
Although Oenocarpus bataua is not known to be naturalized in Hawaiʻi, it possesses traits that are cause for concern, including bird- and animal-dispersed seeds and the ability to establish in tropical forest environments. In suitable conditions, palms like this can potentially spread beyond cultivation and compete with native vegetation, particularly in lowland wet forests. Its fruit production may attract wildlife that could further aid dispersal if it were to establish locally. Ongoing evaluation is needed to determine whether this species could negatively impact Hawaiʻi’s ecosystems, and caution is recommended to ensure it does not become invasive in the islands.

High Risk Traits:

• Native to tropics
  
• Shade-tolerant when young
  
• Forms dense stands (may outcompete other plants)
  
• Hybridizes naturally with other Oenocarpus species
  
• Dispersed intentionally by people (sold in nurseries)
  
• Dispersed by water, birds, and animals (seeds survive gut passage)

Low Risk Traits:

• Not naturalized or weedy elsewhere
  
• No spines, thorns, or burrs
  
• Non-toxic (edible fruit and oil)
  
• Long time to maturity (8–15 years)
  
• Not a prolific seed producer
