FIGURE 3. Map of Madagascar showing the distribution of the various observations of Gastrodieae on the island. Didymoplexis avaratraensis and D. recurvata, both endemic to Madagascar, co-occur in the northern province of Antsiranana, in evergreen wet forest at mid elevation (Cribb et al. 2013). Didymoplexis verrucosa, also known from South Africa, was recently photographed in the western province of Mahajanga, in deciduous seasonally dry forest (Cribb et al. 2011). Gastrodia madagascariensis occurs in the eastern province of Toamasina opposite the island Nosy Boraha, in evergreen wet forest at low elevation. Filled triangles: flowers observed. Open triangle: only fruits observed.
