Motivation Geographic occurrences are essential for biodiversity studies, but publicly available repositories like GBIF often contain errors and biases, especially for taxonomically complex groups like Carex L. (Cyperaceae). This work provides an expert‐curated global dataset of occurrences compiled from different sources to enhance data accuracy and usability. The final dataset includes 384,067 occurrences of 1790 Carex speci...

Aspalathus linearis (Burm.f.) R.Dahlgren, or rooibos, is an important commercial crop in the Western Cape, South Africa. The growth rate of rooibos is highest during the hot, dry summers typical for this region. This suggests that the plants have a wide range of adaptive responses including morphological, physiological, molecular, and biochemical mechanisms that help them cope with drought and heat stress. This study investiga...

Indigofera L. is the most diverse genus in the tribe Indigofereae and the third largest genus in the Fabaceae with over 750 species distributed in most tropical to temperate areas of the world. The centre of diversity of the genus lies on the African continent, accounting for over two-thirds of its global diversity. Diversification of Indigofer a’s four main clades began in the Early Miocene, with the Tethyan and Cape Clades h...

The New Zealand monotypic sedge Desmoschoenus is indistinguishable from the predominantly temperate South African Ficinia . Both genera share the presence of a condensed paniculate inflorescence and seeds bearing a gynophore, and Desmoschoenus is embedded within a Ficinia DNA phylogeny. Therefore, the current recognition of Desmoschoenus as a distinct genus cannot be justified, and we provide nomenclatural changes to merge the...

Lobelia glaberrima is a newly described species from mountainous parts of the southern South Island of New Zealand. The morphology of L. glaberrima is most similar to L. macrodon , but it is distinguished from that species by a suite of mainly floral characters. These include L. glaberrima having narrower calyx lobes, a corolla with a shorter tube and smaller lobes, shorter stamens with smaller anthers, a smaller ovary with a...

Aims To produce representative aggregate maps of plant collection locations in Thailand and discuss their impact on biogeographical studies in Thailand and the surrounding region. Location Thailand. Methods A representative data set comprising 6593 plant specimen records for Thailand has been assembled. The data set contains ± all known collections for fifteen representative plant families and further records for another 104....
