--><span class="statement" id="st-undefined" data-properties=""><b>Shrubs </b>or trees, (sometimes with woody burl, resprouting after fire). <b>Stems</b> erect to arching; twigs hairy, sometimes glabrescent (sometimes also lepidote). <b>Leaves</b> deciduous or persistent; blade elliptic, obovate, or ovate, membranous to coriaceous, margins entire, undulate, or serrulate [irregularly serrate], plane or revolute, surfaces multicellular, peltate-scaled or short-stalked stipitate-glandular-hairy, often unicellular-hairy on major veins or abaxial surface; venation brochidodromous (or reticulodromous). <b>Inflorescences</b> axillary fascicles, panicles, or racemes, (2–)5–8(–12)-flowered, sometimes flowers solitary, (produced just before flowering). <b>Pedicels</b>: bracteoles 2, at or near base. <b>Flowers</b>: sepals usually [4–]5[–8], slightly connate, ovate-deltate to lanceolate; petals usually [4–]5[–8], connate nearly their entire lengths, white to red, corolla cylindric to urceolate, lobes much shorter than tube, (sparsely stipitate-glandular-hairy or peltate-scaled); stamens usually [8–]10[–16], included; filaments geniculate, flattened, roughened or hairy, with or without spurs; anthers without awns, dehiscent by elliptic pores; pistil usually [4–]5[–8]-carpellate; ovary [4–]5[–8]-locular; (style slightly longer than stamens); stigma capitate-truncate. <b>Fruits</b> capsular, globose to ovoid or ellipsoid, dry, (with [4–]5[–8] pale, decidedly thickened, whitish sutures). <b>Seeds</b> ca. 100–300, ellipsoidal, narrowly oblong, obovoid to angular-obovoid or narrowly conic, (sometimes tailed); testa cells elongate. <b>x</b> = 12.</span><!--
