Morphological and molecular investigations of taxon relationships among rare species of Tetratheca Sm. occurring near Koolyanobbing, Western Australia, have confirmed the distinctness of T. aphylla F.Muell., T. harperi F.Muell. and T. paynterae Alford and identified three new rare taxa from...
The limits, definitions and relationships of Carpha have been controversial and unclear. This study using cladistic analyses of morphological and combined morphological and molecular data indicates that: (1) Carpha sensu latu is paraphyletic and its species form two clades, consistent with the...
The scarce fossil wood record of Proteaceae is complemented with the addition of a new morphogenus with two new species from the Oligocene of Patagonia, Scalarixylon patagonicum , gen. nov., sp. nov., and S. grandiradiatum , gen. nov., sp. nov. They become the first two fossil species that have...
The relationships among rare ‘leafless’ species of Tetratheca Sm. occurring on banded ironstone ranges near Koolyanobbing, Western Australia, and allied, unclassified, populations from Eneabba, Newdegate and the Die Hardy Range have been assessed by molecular characters. These findings, in...
The genus Pouteria Aublet is a pantropical group and many of its species produce high-quality timber and edible fruit. In 1991, on the basis of morphological characters, Pennington combined the genus Planchonella Pierre with Pouteria , expanding the latter genus to nine sections and 325 species....
Boodlea composita (Harvey) F. Brand and Phyllodictyon anastomosans (Harvey) Kraft & M.J. Wynne, two widespread tropical siphonocladalean green algae, have had a long and confusing history because of the vague taxonomic boundaries between the two species. Molecular phylogenetic studies on the...
