--><span class="statement" id="st-undefined" data-properties=""><b>Annuals,</b> biennials, or perennials; (sometimes suffrutescent); scapose or not; glabrous, glabrescent, or pubescent. <b>Stems</b> erect or ascending, branched. <b>Leaves</b> basal and, sometimes, cauline; petiolate or sessile; basal rosulate or not, petiolate, blade margins dentate, sinuate, or pinnatisect; cauline petiolate or sessile, blade (base not auriculate), margins entire or dentate. <b>Racemes</b> (corymbose, sometimes shortly bracteate basally), considerably elongated in fruit. <b>Fruiting</b> pedicels ascending, divaricate, or reflexed, stout to slender. <b>Flowers</b>: sepals ascending to spreading, oblong, lateral pair not saccate basally; petals yellow or white [purple], obovate, (apex rounded or truncate); stamens tetradynamous; filaments not dilated basally; anthers oblong to ovate, (apex obtuse); nectar glands (4): lateral cushionlike, median cylindrical. <b>Fruits</b> siliques, dehiscent, sessile or (long-)stipitate, segments 1 or 2, linear to linear-oblong, torulose, latiseptate or terete; (proximal segment numerous-seeded, 1-veined; terminal segment 0–2-seeded); valves glabrous; replum rounded; septum complete; ovules [12–]20–36(–46)[–276] per ovary; (style obsolete or distinct); stigma capitate or somewhat decurrent, 2-lobed. <b>Seeds</b> usually biseriate, rarely uniseriate, not winged, ovoid or ellipsoid; seed coat (smooth or minutely reticulate), slightly mucilaginous or not when wetted; cotyledons conduplicate. <b>x</b> = 7, [8, 9, 10,] 11, [13,] 21.</span><!--
