Pandaceae is a monophyletic group of three genera that was often regarded as part of the Euphorbiaceae, but of which molecular based phylogenies show it to be a distinct family. Malesia comprises two genera, Galearia (five species) and Microdesmis (two species) of which the taxonomic status, wood and pollen is discussed in a general way. The genus and species treatments contain descriptions, drawings, keys, distribution maps, and notes on habitat, ecology, uses, etc.
