Cardamine limprichtiana Pax, Jahresber. Schles. Ges. Vaterl. Cult. 89, Abt. 2: 27. 1911; Alliaria grandifolia Z. X. An; C. hickinii O. E. Schulz.
Herbs annual or perennial, (12-)25-45(-80) cm tall. Stems erect, simple at base, often branched above, somewhat flexuous, glabrous or sparsely to densely pilose with trichomes to 1.5 mm. Basal leaves not rosulate, simple or with 1-3 lateral lobes on each side; petiole (3-)5-15(-18) cm, flattened at base; blade or terminal leaf lobe cordate to broadly so, (2-)4-8(-10) × (1.5-)2.5-6(-8) cm, glabrous or sparsely to densely subappressed pilose abaxially, glabrous or sparsely pilose adaxially, sometimes ciliate, base cordate or rarely cordate-truncate, margin coarsely crenate with teeth ending in apiculae, apex acute or acuminate; lateral lobes sessile or petiolulate, 0.1-3 × 0.03-2 cm, sometimes absent. Uppermost cauline leaves petiolate, much smaller to much larger than basal ones and up to 18 × 11 cm, base not auriculate, margin coarsely and irregularly dentate, rarely crenate, apex caudate or acuminate. Fruiting pedicels divaricate or recurved, glabrous or pilose, narrower than fruit, (0.5-)1-3(-3.5) cm. Sepals oblong, ascending, 2-3.5 × 1-1.5 mm, base slightly saccate. Petals white, broadly obovate or narrowly obcordate, (6-)7-9 × 3-6 mm, apex shallowly emarginate; claw obscurely differentiated, shorter than sepals. Filaments 2.5-3.5 mm; anthers oblong, 1-1.5 mm, minutely apiculate. Ovules 20-35 per ovary. Fruit narrowly linear, stout, terete, (2-)3-6 cm × 1.5-2 mm; valves glabrous or sparsely pilose, strongly torulose, inconspicuously veined; style terete, 1-3 mm; stigma 2-lobed, slightly decurrent. Seeds oblong, 2-3 × 0.8-1.2 mm. Fl. Mar-May, fr. Apr-Jun.
* Grassy areas along streams, moist slopes, roadsides, rocky slopes; 300-1200 m. Anhui, Zhejiang.
Cardamine limprichtiana and Alliaria grandifolia were both recognized in FRPS and Fl. Zhejiang (3: 51, 55. 1993) as distinct species in two different tribes (Arabideae and Sisymbrieae, respectively). However, examination of the type collections of both species and ample additional material reveal that they are conspecific and belong to Orychophragmus in the tribe Brassiceae.
Orychophragmus limprichtianus was recorded from Sichuan in Fl. Sichuan. (14: 87. 1999, as Cardamine limprichtiana), but the present authors have seen no material from that province.
