Description
The Podalyrieae arose 30.5 ± 2.6 million years ago (in the Oligocene) in the fynbos (Cape Floristic Region) of South Africa and is still mostly found there.[5][6] All members of the tribe exhibit either nonsprouting or sprouting fire survival strategies.[7] Many species are pollinated by insects, especially carpenter bees,[4] while others are pollinated by sunbirds or rodents.[5]
The members of this tribe consistently form a monophyletic clade in molecular phylogenetic analyses.[1][4][5][8][9][10][11][12][13][14] The tribe does not currently have a node-based definition, but several morphological synapomorphies have been identified:
"imparipinnately compound leaves, axillary racemose inflorescences, carboxylic acid esters of quinolizidine alkaloids, and the isoflavone 3′-hydroxydaidzein as a major seed flavonoid"[1][5][15] as well as "strongly reduced or absent bracteoles and the occurrence of persistent antipodals in the female gametophyte."[4]
