  • American Journal of Botany 87(7): 1029–1043. 2000. PHYLOGENETIC RELATIONSHIPS WITHIN THE GENTIANALES BASED ON NDHF AND RBCL SEQUENCES, WITH PARTICULAR REFERENCE TO THE LOGANIACEAE 1
    2013
    Co-Authors: Maria Backlund, Bengt Oxelman, Birgitta Bremer
    Abstract:

    Phylogenetic relationships in the Gentianales with focus on Loganiaceae sensu lato are evaluated using parsimony analyses of nucleotide sequence data from the plastid genes rbcL and ndhF. Inter- and intrafamilial relationships in the Gentianales, which consist of the families Apocynaceae (including Asclepiadaceae), Gelsemiaceae, Gentianaceae, Loganiaceae, and Rubiaceae, are studied and receive increased support from the combination of rbcL and ndhF data, which indicate that the family Rubiaceae forms the sister group to the successively nested Gentianaceae, Apocynaceae, and Loganiaceae, all of which are well supported. The family Gelsemiaceae forms a distinct, supported group sister to Apocynaceae. The Loganiaceae sensu stricto form a strongly supported group consisting of 13 genera: Antonia, Bonyunia, Gardneria, Geniostoma, Labordia, Logania, Mitrasacme, Mitreola, Neuburgia, Norrisia, Spigelia, Strychnos, and Usteria. These genera form two well-supported lineages. Several members of Loganiaceae sensu Leeuwenberg and Leenhouts, i.e., Androya, Peltanthera, Plocosperma, Polypremum, and Sanango are clearly not members of the Gentianales. The earlier exclusion of Buddlejaceae (including Buddleja, Emorya, Gomphostigma, and Nicodemia) as well as the reclassification of the genera Nuxia and Retzia to Stilbaceae of the Lamiales are all well supported.

  • CLADISTICS AND FAMILY LEVEL CLASSIFICATION OF THE GENTIANALES
    Cladistics, 1994
    Co-Authors: Lena Struwe, Victor A. Albert, Birgitta Bremer
    Abstract:

    The most recent classification of the angiosperm order Gentianales (Thorne, 1992) includes four principal families: Apocynaceae, Gentianaceae, Loganiaceae, and Rubiaceae. Ever since Bentham (1857) the status of Loganiaceae has been questioned, and several
