Family: Melastomataceae
High Risk Traits:
- Naturalized: Hawaii (Kaua‘i, O‘ahu, Maui, Hawai‘i), Australia, Palau, Samoa.
- Weed: Agricultural weed (Africa, Australia) and environmental weed (Palau, Samoa), forming dense mats that exclude other species.
- Climate: Highly suited to tropical/subtropical climates.
- Shade tolerant: Establishes in forest understories.
- Growth habit: Creeping groundcover that can climb and smother other plants.
- Reproduction: Spreads vegetatively via fragments; intentionally planted by people.
- Response to mutilation: Fragmentation aids spread, complicating mechanical control.
Low Risk Traits:
- Habitat specificity: Demands moist conditions, limiting spread in drier areas.
- Physical/chemical traits: No spines, burrs, or evidence of toxicity.
- Seed dispersal: Not adapted for wind, bird, or external animal dispersal.
- Seed production: Fruit infrequently formed in cultivation.
- Herbicide control: Reported to be effectively controlled with chemicals.
