The Genistoids are one of the major radiations in the plant family Fabaceae. Members of this phylogenetic clade are primarily found in the Southern hemisphere.[1][3][4] Some genera are pollinated by birds.[3] The genistoid clade is consistently resolved as monophyletic in molecular phylogenetic analyses.[1][3][4][7][8][9][10][11] It is estimated to have arisen 56.4 ± 0.2 million years ago (in the Paleocene).[8] A node-based definition for the genistoids is: "the MRCA of Poecilanthe parviflora and Lupinus argenteus."[1] One morphological synapomorphy has been tentatively identified: production of quinolizidine alkaloids.[1][12][13][14] Some genera also accumulate pyrrolizidine.[3][4] A new genus, to be segregated from Clathrotropis, has also been proposed to occupy an undetermined position within the genistoid clade.[3][4]

Core Genistoids

The core genistoids, also known as the genistoids sensu stricto, comprise most of the tribes of the genistoids sensu lato, and are found mainly in Africa and Eurasia.[4] This subclade is also consistently resolved as monophyletic.[1][3][4][5][7][8][9] A node-based definition for the core genistoids is: "the MRCA of Bolusanthus speciosus and Spartium junceum.[1]
