A genus of about 45 species, herbs (our introduced species), shrubs, and trees, native of tropical and subtropical Asia and Australia. Previously included in Phyllanthus; see Bouman et al. (2021, 2022).
ID notes:Our one alien species can be an aggressive weed in disturbed soils. The distichous leaves arrayed along the horizontal ultimate stems are very easily mistaken for the leaflets of a pinnately compound leaf. The leaves have a distinctive dark green color, typically grading to paler green near the pale green stem.
