FIG. 3. Multivariate analysis of morphological and ecological data, and geographic distribution areas of selected Dalbergia taxa from eastern Madagascar. See Tables 1–2 for variable codes. A. PCoA biplot of 13 leaf and leaflet characters (arrows) measured in 57 collections with mature leaves. B. PCoA biplot of 11 inflorescence and flower characters (arrows) measured in 17 collections with flowers. C. PCA biplot of 17 ecological characteristics (arrows) for 330 collections made since 2000 with precise geo-coordinates. Shading for D. chapelieri s.l. has been omitted for clarity. D. Combined distribution map based on buffered alpha hulls drawn around 423 geolocations, including collection records from before 2000, and nine records from the undescribed SAVA material, and excluding two extreme occurrences considered extinct (Service Forestier 38-R-118 and 34291). Note that D. maritima subsp. maritima and D. louvelii s.s. co-occur in the Atsinanana Region.
