An update on Quararibea floribunda (Malvaceae: Malvoideae): untangling the taxonomy and geographic distribution
<p>Quararibea floribunda, a species endemic to Brazil, is poorly studied taxonomically, and little is known about its ecology and conservation status. Since its publication in 1842, only a few studies have reported on its morphological circumscription, thus remaining as a complex in the taxonomy of Quararibea. In addition, little is known about its geographic distribution, which, according to most authors, is restricted to the Cerrado Biome, a phytogeographic biome of dry forests. Therefore, we herein review and clarify the morphological circumscription and distribution of Q. floribunda in different vegetation types, designate a lectotype, and recognize its conservation status as Vulnerable (VU). The present study is based on analysis of protologues and further pertinent literature. Several herbaria were consulted, both in person and online. Fieldwork was done between 2017 and 2020 in different locations of midwestern and southeastern Brazil, mainly in dry forests of the Cerrado Biome. We confirm that Q. floribunda also occurs in the Atlantic Forest Biome and that it is not exclusive to the Cerrado Biome, as previously thought. All known populations in this biome inhabit humid habitats, and as such, they are closer to the vegetation of the Atlantic Forest Biome than the typical Cerrado dry forests. In addition to assessing the conservation status of Q. floribunda, we evaluate its nomenclatural history, leading to the designation of a lectotype, finally highlighting vegetative and floral diagnostic characters. A distribution map is provided, as well as a morphological comparative analysis between species with foliar domatia in extra-Amazonian Brazil.</p>
Alignments and tree files from: Phylogenetic relationships within tribe Hibisceae (Malvaceae) reveal complex patterns of polyphyly in Hibiscus and Pavonia
<p>The diverse and spectacular Hibisceae tribe comprises over 750 species. No studies, however, have broadly sampled across the dozens of genera in the tribe, leading to uncertainty in the relationships among genera. The non-monophyly of the genus <em>Hibiscus </em>is infamous and challenging, whereas the monophyly of most other genera in the tribe has yet to be assessed, including the large genus <em>Pavonia</em>. Here we significantly increase taxon sampling in the most complete phylogenetic study of the tribe to date. We assess monophyly of most currently recognized genera in the tribe and include three and thirteen newly sampled sections of <em>Hibiscus </em>and <em>Pavonia</em>, respectively. We also include five rarely sampled genera and 137 species previously unsampled. Our phylogenetic trees demonstrate that <em>Hibiscus</em>, as traditionally defined, encompasses at least 20 additional genera. The status of <em>Pavonia </em>emerges as comparable in complexity to <em>Hibiscus</em>. We offer clarity in the phylogenetic placement of several taxa of uncertain affinity (e.g., <em>Helicteropsis, Hibiscadelphus, Jumelleanthus, and Wercklea)</em>. We also identify two new clades and elevate them to the generic rank with the recognition of two, new monotypic genera: 1) <em>Blanchardia </em>M.M.Hanes & R.L.Barrett is a surprising Caribbean lineage that is sister to the entire tribe, and 2) <em>Astrohibiscus </em>McLay & R.L.Barrett represents former members of <em>Hibiscus caesius</em> s.l. <em>Cravenia </em>McLay & R.L.Barrett is also described as a new genus for the <em>Hibiscus panduriformis</em> clade which is allied to <em>Abelmoschus</em>. Finally, we introduce a new classification for the tribe and clarify the boundaries of <em>Hibiscus </em>and <em>Pavonia</em>.</p>
