--><span class="statement" id="st-undefined" data-properties=""><b>Annuals,</b> biennials, or perennials, 10–80+ cm. <b>Stems</b> erect or spreading, branched from bases or throughout. <b>Leaves</b> mostly cauline; all or mostly opposite or all or mostly alternate; petiolate or sessile; blades usually 1–2-ternately lobed (blades or lobes mostly filiform, lanceolate, linar, oblanceolate, oblong, or ovate), ultimate margins toothed or entire, faces sparsely to densely hairy (hairs white, straight, conic or fusiform, 0.1–0.3 or 0.3–0.8 mm), often gland-dotted as well. <b>Heads</b> radiate, borne singly or in loose, corymbiform arrays. <b>Involucres</b> ± hemispheric or broader, 6–14+ mm diam. <b>Phyllaries</b> persistent, 8–18+ in ± 2 series (reflexed in fruit, distinct, subequal or outer smaller, mostly lanceolate or oblanceolate, thin-herbaceous, margins membranous, rarely purplish). <b>Receptacles</b> convex, smooth or knobby, epaleate. <b>Ray</b> florets 5–15, pistillate, fertile; corollas yellow (sometimes pale). <b>Disc</b> florets 25–120+, bisexual, fertile; corollas yellow (hairy), tubes shorter than or about equaling cylindric or campanulate to funnelform throats, lobes 5, deltate to lance-ovate. <b>Cypselae</b> obpyramidal, 4-angled, ± hirtellous to ± sericeous; pappi persistent, of 6–12 distinct, spatulate or oblanceolate to ovate or quadrate, basally and/or medially thickened, distally and/or laterally scarious scales in ± 1 series (apices usually muticous, sometimes some or all ± aristate). <b>x</b> = 12.</span><!--

--><p><i>Bahia</i> dissecta is treated here in <i>Amauriopsis</i>; B. oppositifolia and B. woodhousei are treated in <i>Picradeniopsis</i>; B. nudicaulis is treated in <i>Platyschkuhria</i>. These departures from the treatment of <i>Bahia</i> in a broad sense by W. L. Ellison (1964) are consistent with findings by B. G. Baldwin et al. (2002).</p>
