Until recently this small family was only known to occur in New Zealand and New Caledonia, but in 1982 I have shown that it occurs in New Guinea and in 1984 that it is also represented in East Australia. Its phytographic history is complicated through the former confusion about the systematic affinity. Wittsteinia was described by F. VON MUELLER (1861) as probably belonging to Ericaceae (or Pyrolaceae). Periomphale was described by BAILLON (1888) and has been affiliated to Caprifoliaceae or Gesneriaceae. In the ‘Pflanzenfamilien’ it was ranged among incertae sedis (Nachtr., 1897). GILG & SCHLECHTER (1906) described two other genera from New Caledonia which have appeared not to be different from Periomphale.
