    Sammanfattning : Biodiversity in the tropics is disproportionately high compared to other habitats, and also under disproportionate threat from human impact. It is necessary to understand how this diversity evolved and how it is partitioned across space in order to preserve it. LÄS MER

    Sammanfattning : Background. Caryophyllaceae is a large and cosmopolitic flowering plant family, however the systematics of many of its basal groups has been unclear, due to a lack of unambiguous morphology. Some members of Caryophyllaceae are used medicinally, e.g. LÄS MER

    Sammanfattning : Selaginellaceae, spikemosses, is a heterosporous plant family belonging to the lycophytes. With an estimated age of some 350 million years, the family is historically important as one of the oldest known groups of vascular plants. Selaginellaceae is herbaceous with a worldwide distribution. However, the majority of the ca. LÄS MER
