Abstract: The Neotropical genus Melothria (Benincaseae, Cucurbitaceae) is a small group of yellow- or white-flowered climbers with small to medium-sized fruits. In 1899, Alfred Cogniaux described a species from montane rainforest in Haiti as Melothria domingensis, presumably based on the overall similarity in habit, leaf shape, and fruit morphology of his incomplete herbarium material to other Central American Melothria species. Melothria domingensis is still rare in European and American herbaria and the species has never been studied in detail. We here present molecular and morphological analyses, which show that the species is misplaced in Melothria and instead belongs in the distantly related tribe Cucurbiteae in the genus Cayaponia. We illustrate the species, provide the formal transfer and an extended description, and discuss the phylogenetic, biogeographic and ecological implications, including the finding that most likely bee- and not bat-pollination is ancestral in Cayaponia.

Description and molecular diagnosis of a new species of Brunfelsia (Solanaceae) from the Bolivian and Argentinean Andes https://phytokeys.pensoft.net/article/1408/ PhytoKeys 10: 83-94

DOI: 10.3897/phytokeys.10.2558

Authors: Natalia Filipowicz, Michael Nee, Susanne Renner

Abstract: Brunfelsia plowmaniana N.Filipowicz & M.Nee sp. nov., a species from humid and cloud forests of the Bolivian and Argentinean Andes, is described and provided with a molecular diagnosis, using provisions available in the recently approved International Code of Nomenclature for algae, fungi and plants. Specimens belonging to the new species were previously placed in the polymorphic B. uniflora (Pohl) D.Don, which a molecular phylogeny revealed as polyphyletic. Revision of numerous collections revealed clear morphological differences between the new species and B. uniflora, the type locality of which is in the state of São Paulo, Brazil.
