Crotalarieae is a tribe of flowering plants belonging to the family Fabaceae. It includes rooibos (Aspalathus linearis), harvested for sale as a tisane. Description The Crotalarieae arose 31.2 ± 3.4 million years ago (in the Oligocene). The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses. The tribe does not currently have a node-based definition and no morphological synapomorphies have been identified. Several genera in the tribe produce quinolizidine alkaloids or macrocyclic pyrrolizidine alkaloids. Genera Crotalarieae comprises the following genera: Aspalathus L. Bolusia Benth. Calobota Eckl. & Zeyh. Crotalaria L. Euchlora Eckl. & Zeyh. Ezoloba B.-E. van Wyk & Boatwr. Lebeckia Thunb. Leobordea Del. Listia E. Mey. Lotononis (DC.) Eckl. & Zeyh. Pearsonia Dummer Rafnia Thunb.
