Micranthemum Michaux.
A genus of 14-17 species, annual herbs, of s. North America, Central America, and South America. The recognition of Hemianthus as separate from Micranthemum is uncertain and needs additional study; Fischer, Schäferhoff, & Müller (2013) show that Micranthemum is very close to Lindernia s.s., but leave it separate for now (based on inadequate sampling).
