--><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>Parrya is a distinctive genus reduced by V. P. Botschantzev (1972) to being monospecific, including only P. arctica, 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>
