Data for: From southern Africa and beyond: historical biogeography of a monocotyledonous bulbous geophyte
<p><em><strong>Aim</strong></em></p> <p>Low taxon sampling and taxonomic uncertainties still obscure our evolutionary knowledge of many taxa, especially widespread lineages across diverse landscapes. Of particular interest are those lineages inhabiting seasonal and arid landscapes, which showcase unique distributional patterns that hint at fascinating histories. Using the most comprehensive sampling to date of a widespread bulbous monocot, we hypothesize two independent dispersals to Madagascar, and that vicariance due to Miocene-driven aridification contracted a once-widespread distribution between Africa and Eurasia.</p> <p><em><strong><span>Location</span></strong></em></p> <p><span>Sub-Saharan Africa, Madagascar, Eurasia</span></p> <p><em><strong>Taxon</strong></em></p> <p>Ledebouriinae (Scilloideae, Asparagaceae)</p> <p><em><strong>Methods</strong></em></p> <p>Using the Angiosperms353 probe set for 195 taxa (86 ingroup taxa), we perform phylogenetic reconstruction using IQ-Tree, and we infer age estimates using penalized likelihood as implemented in treePL. Capitalizing on our broad geographic sampling, which includes African, Malagasy, and Eurasian taxa, we use 'BioGeoBEARS' to reconstruct ancestral ranges and investigate the role of vicariance and dispersal. </p> <p><em><strong>Results</strong></em></p> <p>The Ledebouriinae originated within the past ~30 myr in southeastern sub-Saharan Africa, with the major subclades arising soon thereafter. Although long-distance dispersal cannot be fully ruled out, we argue that vicariance was the major process responsible for the current distribution of <em>Ledebouria</em> in Eurasia. We recover two distinct <em>Ledebouria</em> groups that overlap in eastern Africa, but are divided into mostly northern and southern clades with divergent biogeographical histories, each showing an independent dispersal to Madagascar. A similar north-south split is seen in <em>Drimiopsis</em>. Additionally, we recover a complex biogeographic history in the predominantly sub-Saharan African Ledebouria clade, with a rapid radiation at ~14 mya.</p> <p><em><strong>Main conclusions</strong></em></p> <p>The expansion of seasonal rainfall and aridity in sub-Saharan Africa, coupled with orogenic activity, may have fostered the diversification of the Ledebouriinae and many subclades. Miocene-driven aridification may have caused fragmentation of a once widespread distribution that led to their occurrence in Eurasia.</p>

A taxonomic revision of the Argyrolobium robustum and A. transvaalense groups (Fabaceae) in southern Africa
<p><span>Previous studies on the genus <em>Argyrolobium </em>(Genisteae, Fabaceae) in southern Africa recognized a group of species defined by a suffrutescent habit, monomorphic flowers and leaves, and the plants not turning black when dried as 'section <em>A. transvaalense</em>'. A formal rank was never published for this group. Here a taxonomic study of this group is conducted, including comprehensive descriptions of and a key to the species, nomenclature, typifications, diagnostic characters, and geographical distribution. Based on an assessment of morphological characters, two groups can be recognised; 1) the <em>A. robustum</em> group that comprises four species with a herbaceous habit with up to 55-flowered inflorescences, flowers drying black or turning black when damaged, keel petals lacking pockets, and staminal sheaths fully open above, and 2) the <em>A. transvaalense</em> group comprising five species with a suffruticose habit with up to 24-flowered inflorescences, flowers becoming discoloured (darker coloured or brown) when dried, keel petals with pockets except in <em>A. megarhizum</em>, and staminal sheaths variously fused into a closed tube.</span></p>
