Evolution and systematics of subfamily Detarioideae

Detarioideae is one of the early diverging clades within legumes and has recently been recognised at the subfamily level by the Legume Phylogeny Working Group. The subfamily comprises 81 genera and c. 760 species distributed across the world tropics. The Detarioideae lineage is unusually variable and phylogenetically labile in flower morphology. Recurrent switches in flower morphology are detected across the subfamily, with species ranging from having radially symmetrical flowers with five petals, to having a single large petal or three larger petals in a bilateral arrangement, or entirely lacking petals.
Although no single Detarioideae genus has been found to fix nitrogen, Detarioideae are known to be associated with mycorrhizal fungi; and this association may have played an important role in shaping the diversity and evolution of the group. Many of the tree species belonging to this subfamily dominate large expanses of forest, especially in tropical Africa, where Detarioideae trees can form single species dominated groves; and include some of the hyperdominant species of the Amazon.
This Detarioideae symposium aims to: (i) share results of recent taxonomic efforts in understanding Detarioideae diversity; (ii) show the importance of flower variability and plant-pollinator relationships in the evolutionary patterns observed within Detarioideae; (iii) link phylogenetic and biogeographic studies of Detarioideae clades; and (iv) deepen our understanding of the mycorrizhal associations within Detarioideae and their role in the subfamily dominance of tropical forests.
