Aeschynomene Explained

Aeschynomene is a genus of flowering plants in the family Fabaceae, and was recently assigned to the informal monophyletic Dalbergia clade of the Dalbergieae. They are known commonly as jointvetches. They range across tropical and subtropical regions of the Americas, sub-Saharan Africa, south, southeast, and east Asia, and Australia. These legumes are most common in warm regions and many species are aquatic.

The genus as currently circumscribed is paraphyletic and it has been suggested that the subgenus Ochopodium be elevated to a new genus within the Dalbergieae, though other changes will also be required to render the genus monophyletic.^{[1] [2]} Plants of the World Online currently accepts 114 species.
