FIGURE 7 in Unraveling the Enigma of Androcalymma (Fabaceae: Dialioideae): The Rediscovery of a Critically Endangered Legume Genus in the Heart of the Amazon
FIGURE 7. Maximum likelihood tree presenting the relationship between Androcalymma, few species of Dicorynia, Dialium, and one representative of other 13 Dialioideae genera. Only clades with 60% or higher bootstrap values (represented above each node) are shown. At the center a short representation of the clade containing Androcalymma, Dicorynia, and Dialium with examples of flowers (left) and a floral diagram (right) of each group. Note the trimerous corolla of Dicorynia, the pentamerous one of Androcalymma and the absence of corolla in most species of Dialium, represented here by an American and an Asian species. Also note two stamens in Dicorynia and most Dialium species and four stamens in Androcalymma. Photos: D. platysepalum: Cerlin Ng; D. guianensis: Herve Galliffet; D. paraensis; A. glabrifolium, D. guianense and the floral diagrams and trees: Marcus Falc"o.
