A phylogenetic study of Pimelea and Thecanthes (Thymelaeaceae): evidence from plastid and nuclear ribosomal DNA sequence data

A phylogenetic study of Pimelea and Thecanthes (Thymelaeaceae): evidence from plastid and nuclear... A comprehensive molecular study, using sequence data from nuclear ITS rDNA and plastid rbc L and mat K exons, rps 16 intron, and the trn L-F intronic and intergenic spacer, was used to assess the taxonomic status of Thecanthes Wikstr., and to evaluate the relationships within Pimelea Banks & Sol. ex Gaertn. and Thecanthes (Thymelaeaceae). Both genera are Australasian and they constitute the subtribe Pimeleinae, which is characterised by a reduction to two stamens. Previous studies indicated a close relationship among Pimelea , Thecanthes and Gnidia L. species from tropical Africa. We conclude that Pimelea and Thecanthes form a strongly supported clade, with Thecanthes possibly included within Pimelea , although we await further data before formally proposing a series of new taxonomic combinations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Australian Systematic Botany CSIRO Publishing

Abstract

A comprehensive molecular study, using sequence data from nuclear ITS rDNA and plastid rbc L and mat K exons, rps 16 intron, and the trn L-F intronic and intergenic spacer, was used to assess the taxonomic status of Thecanthes Wikstr., and to evaluate the relationships within Pimelea Banks & Sol. ex Gaertn. and Thecanthes (Thymelaeaceae). Both genera are Australasian and they constitute the subtribe Pimeleinae, which is characterised by a reduction to two stamens. Previous studies indicated a close relationship among Pimelea , Thecanthes and Gnidia L. species from tropical Africa. We conclude that Pimelea and Thecanthes form a strongly supported clade, with Thecanthes possibly included within Pimelea , although we await further data before formally proposing a series of new taxonomic combinations.
