History

The name "Phyllanthaceae" was first validly published by Ivan Ivanovich Martynov in 1820 in a Russian book entitled ''Tekhno-botanico Slovar.'' A proposal to conserve this name was published in 2007. Martynov's name was rarely used in the 180 years after he published it. During that time, the plants that are now in Phyllanthaceae were placed in the large and heterogeneous family

), and three members of the tribe Scepeae (''Ashtonia'', ''Distichirrhops'', and ''Nothobaccaurea'') have not yet been sampled for DNA. ''Chonocentrum'' is known from only a single specimen collected in the 1850s. In the phylogeny shown below, statistical support for the clades was measured by bootstrap percentage. All branches shown below have

bootstrap support of at least 70%.
