--><span class="statement" id="st-undefined" data-properties=""><b>Perennials </b>[subshrubs]; (caudex well-developed, often covered with persistent petiolar remains or leaves); scapose [not scapose]; glandular or eglandular, glabrous [pubescent]. <b>Stems</b> erect, unbranched. <b>Leaves</b> basal [sometimes cauline]; rosulate; petiolate; blade margins entire, subentire, or dentate [pinnately lobed]. <b>Racemes</b> (corymbose, 3–20-flowered, rarely proximalmost flowers bracteate), considerably elongated in fruit. <b>Fruiting</b> pedicels ascending or divaricate-ascending [erect]. <b>Flowers</b>: sepals ovate or oblong [linear], (unequal, glandular or eglandular); petals purple, lavender, or white [pink], obovate, claw differentiated from blade, (subequaling or longer than sepals, apex rounded or emarginate); stamens tetradynamous; filaments dilated or not basally; anthers oblong [linear], (apex obtuse); nectar glands lateral, annular or semi-annular. <b>Fruits</b> sessile or shortly stipitate (gynophore persistently attached to pedicel), not segmented, linear, oblong, or lanceolate, smooth or torulose, strongly latiseptate or, rarely, subterete or 4-angled; valves (leathery), each with prominent midvein and with obscure to distinct lateral and marginal veins, eglandular or glandular; replum almost always flattened (visible); septum complete; ovules 6–20[–50] per ovary; stigma conical or cylindric, 2-lobed (lobes prominent, connate, decurrent). <b>Seeds</b> often broadly winged, suborbicular to broadly ovate [oblong], strongly flattened; seed coat (smooth), not mucilaginous when wetted; cotyledons accumbent. <b>x</b> = 7.</span><!--

--><p><i>Parrya</i> is a distinctive genus reduced by V. P. Botschantzev (1972) to being monospecific, including only <i>P. arctica</i>, with almost all of the other species transferred to Neuroloma. Except for the four North American species, the genus is centered in central Asia, adjacent western China, and the Himalayas.</p>
