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.[2][8][9] Some genera are pollinated by birds.[8] The genistoid clade is consistently resolved as monophyletic in molecular phylogenetic analyses.[2][8][9][11][12][13][14][15] It is estimated to have arisen 56.4 ± 0.2 million years ago (in the Paleocene).[12] A node-based definition for the genistoids is: "the MRCA of Poecilanthe parviflora and Lupinus argenteus."[2] One morphological synapomorphy has been tentatively identified: production of quinolizidine alkaloids.[2][16][17][18] Some genera also accumulate pyrrolizidine.[8][9] A new genus, to be segregated from Clathrotropis, has also been proposed to occupy an undetermined position within the genistoid clade.[8][9]

Core Genistoids[edit]

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.[9] This subclade is also consistently resolved as monophyletic.[2][8][9][4][11][12][13] A node-based definition for the core genistoids is: "the MRCA of Bolusanthus speciosus and Spartium junceum."[2]

Systematics[edit]

Modern molecular phylogenetics suggest the following relationships:[5][7][9]
