Family: Sapindaceae

Origin, Description & Uses
Melicoccus bijugatus, commonly known as genip, honeyberry, or Spanish lime, is a tropical fruit tree native to Colombia and northern South America, but it is now widely cultivated throughout the Caribbean, Central America, and other tropical regions. This evergreen tree can grow quite large and produces clusters of small green fruits with a sweet, tangy pulp surrounding a large seed. The fruit is commonly eaten fresh and is also used in beverages, desserts, jams, and traditional foods. The tree is valued as a shade and ornamental species and is sometimes planted in home gardens and agroforestry systems because of its attractive canopy and edible fruit.

Risks & Threats
Although Melicoccus bijugatus is not currently known to be naturalized in the Hawaiian Islands, it does possess traits that are cause for concern. The species produces abundant fruit that may be spread by people, birds, or other animals, increasing its potential to establish outside cultivation. As a hardy tropical tree adapted to warm climates, it could potentially compete with native vegetation if it escapes into suitable habitats. At this time, impacts in Hawaii are not well documented, so ongoing evaluation is needed to determine whether this species could negatively affect local ecosystems. Caution is recommended when planting near natural areas, and responsible management can help reduce the risk of unintended spread.

High Risk Traits:

• Naturalized in tropical/subtropical regions (e.g., Florida, Puerto Rico, US Virgin Islands, Galapagos).
  
• Recorded as an environmental weed (forms dense stands, alters forest structure in US Virgin Islands).
  
• Thrives in tropical climates and ascends to 1,000 m; tolerates drought and brief frost.
  
• Tolerates a wide range of soils (pH 5.5–8.0; clay, sand, limestone; poor soils).
  
• Produces viable seeds.
  
• Self-compatible? Possibly (some trees produce both flower types).
  
• Seeds dispersed by birds and bats (short distances) and intentionally by people (long distances).
  
• Seeds survive gut passage (endozoochory).
  
• Tolerates mutilation and responds to herbicide control (but requires active treatment).

Low Risk Traits:

• Unarmed (no spines, thorns, or burrs).
  
• Not toxic to humans or animals (seeds pose choking hazard, not toxicity).
  
• Shade-intolerant (requires full sun for dominance).
  
• No prolific seed production or persistent seed bank.
  
• Slow-growing; minimum generative time 4–7+ years (from seed).
