Indo-Asian Eriolaena expanded to include two Malagasy genera, and other generic realignments based on molecular phylogenetics of Dombeyoideae (Malvaceae)
<p class="AbstractTITLESECTION">Molecular phylogenetic analyses of Malvaceae subfamily Dombeyoideae based on a 6-marker dataset sampling all 21 currently accepted genera (including extinct <span class="Italic">Astyria</span>) yielded improved resolution and evidence for multiple generic circumscription problems. The taxonomy of the subfamily is adjusted with the synonymization of 10 genera (eight in current use) and the description of one new one, for a revised Dombeyoideae comprised of 14 genera and supported by morphological, anatomical, and/or palynological evidence. <span class="Italic">Eriolaena</span> is expanded from a narrow Indo-Asian group to include the Malagasy endemic genera <span class="Italic">Helmiopsis</span> and <span class="Italic">Helmiopsiella</span>, and a recently described species from continental Africa. A conspectus is presented of the new broadly circumscribed <span class="Italic">Eriolaena</span> with 27 species (28 taxa, including 3 new Malagasy species and 16 new combinations) and defined by a unique winged-seed morphology. A new monotypic Malagasy genus (<span class="Italic">Hafotra</span>), resolved as sister to <span class="Italic">Eriolaena</span>, is described. A conspectus is presented of a broadly circumscribed Mascarene-Malagasy <span class="Italic">Ruizia</span> (+<span class="Italic"> Astyria </span>and<span class="Italic"> Trochetia</span>, with 12 new combinations). Two other genera are expanded and recircumscribed: <span class="Italic">Melhania</span> (+<span class="Italic"> Trochetiopsis </span>and <span class="Italic">Paramelhania</span>, with one new name and two new combinations) and <span class="Italic">Corchoropsis </span>(+ <span class="Italic">Paradombeya</span>, with two new combinations). Additionally, two genera are typified, and 21 names are lectotypified.</p>
