Family: Fabaceae
High Risk Traits:
- Elevation range exceeds 1000 m, demonstrating environmental versatility
- Thrives in tropical climates
- Widely naturalized, including Oahu, and possibly Molokai (Hawaiian Islands)
- Weedy plant, potential crop weed
- Other species have become invasive
- Toxic to animals and people
- Host of soybean rust pathogen
- Shade-tolerant
- N-fixing (may alter soil chemistry)
- Reproduces by seed
- Self-pollinating
- Able to reach maturity in one growing season
- Seeds lack a dispersal mechanism, but are likely moved by water when grown in riparian areas
- Forms a persistent seed bank
Low Risk Traits:
- Unarmed (no spines, thorns, or burrs)
- Palatable despite reports of toxicity
- Not reported to spread vegetatively
- Herbicides may provide effective control
- Mechanical control effective in low densities and for young plants
