--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> perennial [annual], often suffrutescent, glabrous or pubescent, sometimes viscid; taproots slender and ropelike to swollen and tuberous. <b>Stems</b> erect to decumbent, unarmed, without glutinous bands on internodes. <b>Leaves</b> petiolate or sessile, ± equal in each pair; blade thin to thick and fleshy, base ± symmetric. <b>Inflorescences</b> terminal and axillary, terminating in pedunculate involucres subtending 1–16 flowers, usually cymose, sometimes consisting of single involucre in leaf axil; bracts persistent, 5, connate or, rarely, distinct, ± ovate, forming weakly to strongly accrescent, herbaceous to papery involucre. <b>Flowers</b> bisexual, chasmogamous and/or cleistogamous; cleistogamous perianth small dome atop basal portion; chasmogamous perianth radially symmetric or slightly bilaterally symmetric, campanulate to funnelform, constricted beyond ovary, tube gradually to abruptly expanded, limb 5-lobed; stamens 3–6, exserted; styles exserted beyond stamens; stigmas capitate. <b>Fruits</b> radially symmetric, with (4–)5 round or angular ribs separated by usually broad sulci, or ribs not well defined or not evident, obovoid, ellipsoid, or nearly globose, smooth or tuberculate, stiffly coriaceous, glabrous or pubescent, without glands.</span><!--

--><p><i>Mirabilis</i> is the most speciose genus of the Nyctaginaceae. A. Heimerl (1934c), in part adapting J. D. Hooker’s (1880) treatment, recognized six sections, five of which occur in the flora. P. C. Standley (1918) recognized segregate genera within the alliance, collapsing them into a broadly circumscribed <i>Mirabilis</i> in 1931. Species-level taxonomy is often equivocal because of the lack of distinguishing reproductive characteristics among forms that are, overall, morphologically and ecologically different. Problems are exacerbated in sect. Oxybaphus by autogamy, xenogamy, perennial nature, and rather high chromosome numbers (R. W. Cruden 1973; R. Spellenberg 1998). Some species are used widely for dyes, cosmetics, food, and medicine (G. M. Hocking 1997; D. J. Mabberly 1997).</p>
