Leptolobieae is a Neotropical, early-branching monophyletic clade of the flowering plant subfamily Faboideae or Papilionaceae that are mostly found in South America.

Description

[edit]

This tribe is composed of five genera, two of which were originally included in the genus Acosmium (Guianodendron[3] and Leptolobium[4]) and one of which was originally assigned to the genus Diplotropis (Staminodianthus[5]). All of these genera were traditionally included in the tribe Sophoreae. However, recent molecular phylogenetic analyses resolved these five genera into a strongly-supported monophyletic clade, which warranted the reinstatement of the tribe Leptolobieae.[2][6] A potential morphological synapomorphy for the tribe is: "tufts of minute colleter-like glands in the axils of bract and bracteoles".[2][6][7]
