    Phyllopentas flava (Rubiaceae), a New Morphologically Heterodistylous and Functionally Dioecious Species from Madagascar2011In: Systematic Botany, ISSN 0363-6445, E-ISSN 1548-2324, Vol. 36, no 4, p. 1024-1027Article in journal (Refereed)
    Abstract [en]

    A new species of the Afro-Malagasy genus Phyllopentas Karehed & B. Bremer, Phyllopentas flava Razafim., T. Andriam. et Karehed, is described and illustrated. This plant is restricted to the Itremo region in southeastern Madagascar and is distinct morphologically from the other species of the genus by its pubescent, narrowly ovate to narrowly elliptic leaves, grey-whitish and thickly hairy midribs and secondary veins on the lower surfaces of leaves, and functionally dioecious and heterodistylous flowers. Summaries of distribution, phenology, habitat, and ecology are given and a conservation assessment is also provided.

    Paracarphalea, a new genus of the coffee family segregated from the Malagasy endemic genus Carphalea (Rubiaceae, Rubioideae, Knoxieae)2016In: Phytotaxa, ISSN 1179-3155, E-ISSN 1179-3163, Vol. 263, no 2, p. 98-112Article in journal (Refereed)
    Abstract [en]

    The Malagasy genus Carphalea (Rubiaceae) consists of six species (C. angulata, C. cloiselii, C. kirondron, C. linearifolia, C. madagascariensis, C. pervilleana) of shrubs or small trees and is recognizable by a distinctly lobed calyx, 2(–4)-locular ovaries, each locule with several ovules on a rod-like stalk arising from the base of the locule, and indehiscent fruits. Carphalea linearifolia, rediscovered in 2010, has not previously been included in any Rubiaceae molecular phylogenetic studies. We re-investigated the monophyly of Carphalea using sequence data from chloroplast (rps16 and trnT-F) and nuclear (ITS and ETS) markers analysed with parsimony and Bayesian methods. Carphalea linearifolia forms a clade with Ccloiselii and the type species C. madagascariensis. This clade is sister to a clade consisting of the rest of the Carphalea species plus the genus Triainolepis. According to these results, the new genus Paracarphalea is here described to accommodate Carphalea angulata, C. kirondron, and C. pervilleana. Theconservation status of Carphalea linearifolia is assessed as critically endangered according to IUCN criteria.

    The family Pennantiaceae and its relationships to Apiales2003In: Botanical journal of the Linnean Society, ISSN 0024-4074, E-ISSN 1095-8339, Vol. 141, no 1, p. 1-24Article in journal (Refereed)
    Abstract [en]

    The early evolution of the flowering plant order Apiales is discussed based on information from morphology and DNAsequences from four genes (ndhF,rbcL,atpBandmatK). A model-based approach of analysis, Bayesian inference, isused to analyse the data and the results are compared with those from parsimony analysis. In particular, a new familyof the order, the monogeneric Pennantiaceae from New Zealand and Australia, aids in the understanding of howthe order originated. The ancestor of Apiales was probably a shrub or small tree with alternate, simple leaves, paniculateinflorescences, five-merous flowers with free petals, and drupes.

    Evolution of the Australasian families Alseuosmiaceae, Argophyllaceae, and Phellinaceae1999In: Systematic Botany, ISSN 0363-6445, E-ISSN 1548-2324, Vol. 24, no 4, p. 660-682Article in journal (Refereed)
    Abstract [en]

    Based on results from cladistic analyses of morphology and DNA sequences (the two chloroplast genes rbcL and ndhF), the three Australasian families Alseuosmiaceae, Argophyllaceae, and Phellinaceae are each monophyletic, belong within Asterales, and together form a monophyletic group. Two new rbcL sequences and thirteen new ndhF sequences were obtained. Congruence tests did not reveal any significant incongruence between the two molecular data sets or between the molecular and morphological data. The character evolution of the Alseuosmiaceae-Argophyllaceae-Phellinaceae group is discussed. The Australasian ancestor of this group was probably a woody plant with simple, alternate, serrate leaves and regular, choripetalous, epigynous flowers borne in panicles. All tree families should be retained in line with the "principle of ease of identification."

    Phylogeny of Hedyotis L. (Rubiaceae Spermacoceae): Redefining a complex Asian-Pacific assemblage2013In: Taxon, ISSN 0040-0262, E-ISSN 1996-8175, Vol. 62, no 2, p. 357-374Article in journal (Refereed)
    Abstract [en]

    The genus Hedyotis (Rubiaceae: Spermacoceae) has long served as a repository for tropical herbaceous species that do not fit readily into other genera. Circumscribed broadly the genus becomes a highly heterogeneous assembly, but relationships of Hedyotis have been difficult to resolve and it has proven very difficult to circumscribe the genus in a more narrow sense. Here we present Bayesian phylogenetic analyses of Hedyotis using plastid (rps16, petD) and nuclear (ITS, ETS) sequence data to resolve monophyletic lineages, to test former taxonomic hypotheses, and to revise the taxa within a well-supported evolutionary framework. Four hundred and sixty-seven sequences representing 129 accessions, never previously included in any phylogenetic analyses, are newly reported. Hedyotis, as previously circumscribed, is polyphyletic, but all investigated species, except for Hedyotis coronaria, are resolved in one of three well-supported monophyletic groups. The largest clade includes all investigated species of Hedyotis from the Indian subcontinent as well as three groups of species with primarily Chinese distributions. The type species of Hedyotis (H. fruticosa) is resolved with the Indian subcontinent species and following previous suggestions this group is referred to as Hedyotis s.str. Species currently recognized under the generic names Metabolos and Pleiocraterium are resolved in Hedyotis s.str. The second-largest group comprises a series of smaller, but well-supported, clades including the Leptopetalum clade, the genus Kadua, an unnamed group distributed in Asia and the Pacific, and a large Asian group referred to here as the ExallagelDimetia clade. The third group includes a few SE Asian Hedyotis, as well as all investigated species of the genus Neanotis. Hedyotis coronaria is not closely related to other species from Asia and is resolved with Spern2acoce hispida. The analyses indicate that diplophragmous capsules and "fruticosa-type" seeds occur outside of Hedyotis s.str., and several species suggested to have these features are resolved in the ExallagelDimetia clade. Species suggested to have indehiscent capsules, a feature used by Bremekamp to characterize the genus Exallage, are also resolved in both the ExallagelDimetia clade and in Hedyotis s.str., but a close examination indicates that the capsules are not truly indehiscent in the Hedyotis s.str. species. One species of Metabolos and one species of Pleiocraterium are given new species names, and one species of Pleiocrateriam is transferred to Hedyotis and three species of Hedyotis are transferred to Neanotis.
