Discussion

Sphagneticola trilobata is probably native to subtropics and tropics of the New World and probably introduced in Old World. It is increasingly cultivated and is to be expected as escaped or persisting in warm to hot, sandy spots anywhere in the flora area. Report of it from Louisiana has not been confirmed.
