--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>often fetid when crushed; not scapose; glabrous or pubescent. <b>Stems</b> erect, unbranched or branched distally. <b>Leaves</b> basal and cauline; petiolate or sessile [subsessile]; basal (often withered in fruit), rosulate or not, petiolate [subsessile], margins entire, repand, dentate, or sinuate-dentate; cauline sessile, blade (base auriculate or sagittate), margins dentate, repand, or entire. <b>Racemes</b> (several-flowered), considerably elongated in fruit. <b>Fruiting</b> pedicels divaricate, (straight or slightly curved), slender. <b>Flowers</b>: sepals erect or ascending, ovate or oblong, (margins membranous); petals spatulate [oblong], claw differentiated or not from blade, (apex obtuse or emarginate); stamens slightly tetradynamous; filaments not dilated basally; anthers ovate, (apex obtuse); nectar glands (2 or 4), lateral, often 1 on each side of lateral stamen, median glands absent. <b>Fruits</b> silicles, sessile, oblong, obovate, obcordate, or suborbicular, (apex often notched), keeled, strongly angustiseptate; valves winged throughout or apically, glabrous; replum rounded; septum complete, (not veined); ovules 6–16 per ovary; style obsolete or not, (included in apical notch); stigma capitate. <b>Seeds</b> plump, not winged, ovoid; seed coat (coarsely reticulate, alveolate or concentrically striate), not mucilaginous when wetted; cotyledons accumbent. <b>x</b> = 7.</span><!--

--><p><i>Thlaspi</i> was divided by F. K. Meyer (1973) into 12 genera largely based on seed-coat sculpture and anatomy. Molecular data (K. Mummenhoff et al. 1997; M. Koch and Mummenhoff 2001) showed that <i>Thlaspi</i> is polyphyletic and strongly supported some of Meyer’s segregates, including <i>Microthlaspi</i> and <i>Noccaea</i>, both of which are recognized in this flora. As here delimited, <i>Thlaspi</i> consists of six species (Meyer), instead of over 75 recognized by various authors.</p>
