This tropical weed has become widely scattered across southeastern states, especially on nitrogen-rich soil in warmer areas (W). It has been found in greenhouses at the Univ. of Ky. in FAYE (JC for KY) and in gardens of JEFF (P. Haragan for EKY), but it is unknown in the wild. Another expected weed of greenhouses is Moeroris.tenellus (Roxb.) R.W. Bouman, formerly treated in Phyllanthus subgenus Kirganelia. M. tenellus originated from the Mascarene Islands in the Indian Ocean, but it has now spread through warmer regions of the world, including southeastern states (W).
