The affinity of the Malesian genus Lophopyxis has a checkered history, a survey of which was given by L.B. Holthuis & H.J. Lam, in Blumea 5 (1942) 205-208, fig. 7. It has been referred to Flacourtiaceae, Icacinaceae, Euphorbiaceae, Olacaceae, and Saxifragaceae. Hitherto no attention was paid to the similarity with Gouania in the Rhamnaceae, which it resembles in toothed leaves, presence of stipules, panicled spike-like inflorescences, and the occurrence of tendrils in these.
