Platycarpha Explained

Platycarpha is a genus of South African plants within the family Asteraceae.^{[1] [2]}

Recent studies have suggested splitting Platycarpha into two genera, Platycarpha and Platycarphella. Further work remains to be done to resolve this.^{[3] [4] [5]}

The name Platycarpha is derived from two Greek words, platys "broad" and karphos "a chip of straw or wood, a scale, a dry stalk".^[6] The name was first used by Christian Friedrich Lessing in 1831.^[7] The type species is Platycarpha glomerata.^[8] This species had been named Cynara glomerata by Carl Peter Thunberg in 1800,^[9] and was moved to Platycarpha by A.P. de Candolle in 1836 in Prodromus Systematis Naturalis Regni Vegetabilis.^[10]

The systematic position of Platycarpha has long been regarded with uncertainty. Most authors have placed it in the tribe Arctotideae^[4] until molecular phylogenetic studies showed it to be closer to Vernonieae.^[11] In 2009, the new tribe Platycarpheae was established for Platycarpha and Platycarphella.^[12]
