Geographical distribution of B. occultum in Madagascar, the Mascarenes (La Réunion, Mauritius) and the Comoro Islands (stippled lines) based on the 22 sample locations of this study (large circles) plus 78 geo-referenced herbarium records and own field data (small circles). The dotted lines in Madagascar indicate 12 ‘Centres of Endemism' (COEs sensu Wilmé et al., 2006), out of which three (dark-shaded areas coded 2, 3 and 5) include sample localities for B. occultum (see Table 1 for identification of population codes).
