Note — Although Melanthesa rhamnoides Blume is the oldest available name for this species, the combination under Breynia is unavailable because of the name of Müller (1866), which is in fact an illegitimate replacement name for Breynia vitis-idaea (Burm.f.) C.E.C.Fischer ( Fischer 1932: 65) . Melanthesa rhamnoides is, contrary to the statement by Govaerts et al. (2000), not illegitimate; the two heterotypic epitheta of rhamnoides were indeed confused by several authors.
