Chonocentrum is a genus of the family Phyllanthaceae described as a genus in 1922. [2] [3] It contains only known species, Chonocentrum cyathophorum, native to the State of Amazonas in northwestern Brazil. [1] [4]

The genus is still not well understood; W. John Hayden has observed that the plant seems have been collected just once, in upper Rio Negro of Brazil in the 1850s, [5] and suggests that it has been misplaced taxonomically. [6] [7]
