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] [4] [5] Some genera are pollinated by birds. [4] The genistoid clade is consistently resolved as monophyletic in molecular phylogenetic analyses. [2] [4] [5] [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. [4] [5] A new genus, to be segregated from Clathrotropis , has also been proposed to occupy an undetermined position within the genistoid clade. [4] [5]
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. [5] This subclade is also consistently resolved as monophyletic. [2] [4] [5] [6] [11] [12] [13] A node-based definition for the core genistoids is: "the MRCA of Bolusanthus speciosus and Spartium junceum ." [2]
Modern molecular phylogenetics suggest the following relationships: [7] [9] [5]
