Species:precatorius

Seeds that are highly toxic when crushed are often utilized in the creation of rosary necklaces. This plant originates from tropical regions and has become invasive, with its seeds dispersed by birds. While it is not frequently cultivated in North Carolina, it has proliferated in Florida, particularly in pinelands, where it has established itself as a troublesome weed. The plant's deep root system poses significant challenges for removal.
