Agelaea is a genus of flowering plants in the family Connaraceae, placed in the order Oxalidales. The genus comprises pantropical woody climbers and shrubs, with species distributed across tropical Africa, Madagascar, and parts of Southeast Asia including Borneo and Cambodia. Connaraceae as a family is characterized by alternate, compound leaves, small flowers, and follicular fruits that often split to reveal seeds with a fleshy aril. Within this family, Agelaea is one of the more species-rich genera, with accepted species recorded from a broad range of tropical forest habitats.
Species listed under Agelaea span a wide geographic range, from West and Central African nations such as Cameroon, Gabon, the Democratic Republic of Congo, and Uganda, to island territories including Annobón, Mayotte, and Príncipe, and eastward into Southeast Asia. The diversity of epithets suggests considerable morphological variation across the genus, though the taxonomy remains unsettled — the distinction between accepted species and synonyms continues to be revised.
Distribution
Agelaea is distributed across the tropics, with the majority of species native to Central and West Africa (including Cameroon, Gabon, the Democratic Republic of Congo, Uganda, and Tanzania), Madagascar, and island territories in the Atlantic and Indian Oceans. A smaller number of species occur in Southeast Asia, including Borneo and Cambodia.
Taxonomy Notes
GBIF records Agelaea as an accepted genus in the family Connaraceae, order Oxalidales, with 3 descendant taxa.
