A Middle-Late Eocene inflorescence of Caryophyllaceae from Tasmania, Australia
A new genus and species (Caryophylloflora paleogenica genus & species nova G.J.Jord. & Macphail) are proposed for a fossil inflorescence found in Middle-Late Eocene sediments at Locharbour, north-eastern Tasmania, Australia. A parsimony analysis of 75 extant species of the order Caryophyllal...

A new genus and species (Caryophylloflora paleogenica genus & species nova G.J.Jord. & Macphail) are proposed for a fossil inflorescence found in Middle-Late Eocene sediments at Locharbour, north-eastern Tasmania, Australia. A parsimony analysis of 75 extant species of the order Caryophyllales and five outgroups placed the fossil within Caryophyllaceae, either subfamily Alsinoideae or Caryophylloideae. The analysis used molecular (rbcL and/or matK), morphological and anatomical data for the extant species, and morphological data for the fossil. Tests on extant species imply that the placement of the fossil should be convincing. The fossil appears to be of a lineage distinct from any extant Australian Caryophyllaceae.
