We review available data for Malagasy <i>Erica</i> (previously treated as <i>Philippia</i>), summarise diagnostic species descriptions and incorporate them into the <i>Erica</i> Identification Aid. There is clearly variation in current species concepts that requires further study. Malagasy <i>Erica</i> most likely represent a single clade also encompassing species from the Mascarenes, but resolution is poor and most species remain unsequenced. <i>Erica</i> is found in several of Madagascar's ecosystems, including the high-altitude \"ericoid thickets\" where diversity is highest, but it is absent from the extensive dry western areas. Habitats include the ericoid thickets, shrubland-grassland mosaics in the central highlands and on the eastern coast, and <i>Uapacabojeri</i> (tapia) savanna. Many <i>Erica</i> species are likely to be part of dynamic ecosystems with infrequent fire regimes. The palaeorecord indicates a more widespread ericoid shrub vegetation during the last glacial period. There may be both wind- and insect-pollinated species. <i>Erica</i> is mainly used as fuelwood in Madagascar, but local uses as tools and medicine have also been reported.
