Family: Fabaceae

Origin, Description & Uses
Schleinitzia insularum is a tropical tree native to islands of the South Pacific, where it grows naturally in wet forest environments. It is a member of the legume family and develops into a medium-sized tree with a broad canopy and compound leaves. The species is valued primarily as an ornamental tree because of its attractive form, lush foliage, and ability to provide shade. In its native range, it contributes to forest ecosystems and may also be used in landscape plantings and restoration projects in suitable tropical climates.

Risks & Threats
Schleinitzia insularum is considered a low-risk species and has not demonstrated significant invasive tendencies. There is little evidence that it spreads aggressively outside cultivation or forms dense stands that displace native vegetation. Like many introduced plants, seedlings may occasionally establish near planted specimens under favorable conditions, but there are no known reports of widespread naturalization or major environmental impacts. As with any non-native species, responsible planting and continued observation are recommended, but current information suggests that this tree poses a relatively low risk to Hawaii’s natural ecosystems.

High Risk Traits:

• Native to broad tropical Pacific region
  
• Nitrogen-fixing woody plant
  
• Produces viable seeds (8–15 per pod)
  
• Hard-seeded with persistent seed bank (>1 year)

Low Risk Traits:

• Not weedy or naturalized outside native range
  
• No known weedy congeners
  
• No spines, thorns, or burrs
  
• Non-toxic and non-allergenic
  
• Poor dispersal: no wind, bird, or external animal adaptation; no human dispersal evidence
