3CD10A05C3565C09A28949CE0B206A25.taxon	diagnosis	Diagnosis. Rorippa daguanensis is similar to R. dubia and R. cantoniensis, but it can be readily distinguished from R. dubia by inconspicuous stems (vs. conspicuous stems), oval silicle 5.5 – 6.5 mm × 2.5 – 3.5 mm (vs. linear silique 2.5 – 4 cm × 0.7 – 0.9 mm) and can be differentiated from R. cantoniensis by the absence of petals and bracts on the flowers (vs. flowers with petals and bracts) and wrinkled pericarps (vs. smooth pericarps).	en	Zhang, Wei, Xiang, Xiao-Yan, Han, Ting-Shen, Shao, Jian-Wen, Zhao, Kai (2025): Rorippa daguanensis (Brassicaceae), a new species from eastern China.

3CD10A05C3565C09A28949CE0B206A25.taxon	description	Description. Herbs annual, 3 – 8 cm tall, glabrous throughout. Stems mostly inconspicuous, with a few erect or decumbent. Leaves petiolate, 10 – 20, forming an open rosette, pinnatisect or almost bipinnatisect, 2 – 10 × 1 – 2 cm, lateral lobes 3 – 10 on each side of mid-vein, 2 – 10 × 1 – 4 mm, incised, dentate or entire. Racemes ebracteate. Fruiting pedicels stout, ascending, 1 – 4 mm. Sepals purple or green, ascending, oblong or subelliptic, 0.8 – 1.2 × 0.2 – 0.4 mm. Petals absent. Filaments 0.8 – 1.2 mm; anthers oblong, 0.1 – 0.3 mm. Ovules 100 – 200 per ovary. Fruit broadly or narrowly oblong, 5.5 – 6.5 × 2.5 – 3.5 mm; pericarp wrinkled, valves thin papery, veinless; style 1 – 1.4 mm. Seeds reddish-brown, ovate or oblate, foveolate, 0.2 – 0.4 × 0.2 – 0.4 mm.	en	Zhang, Wei, Xiang, Xiao-Yan, Han, Ting-Shen, Shao, Jian-Wen, Zhao, Kai (2025): Rorippa daguanensis (Brassicaceae), a new species from eastern China.

3CD10A05C3565C09A28949CE0B206A25.taxon	etymology	Etymology. The specific epithet ‘ daguanensis ’ refers to the type specimen collection locality, Daguan District, Anqing City, Anhui, China.	en	Zhang, Wei, Xiang, Xiao-Yan, Han, Ting-Shen, Shao, Jian-Wen, Zhao, Kai (2025): Rorippa daguanensis (Brassicaceae), a new species from eastern China.

3CD10A05C3565C09A28949CE0B206A25.taxon	distribution	Distribution and ecology. Based on our field survey, Rorippa daguanensis is currently known only from two populations: one located in Qili Lake (QLH), Daguan District, Anqing City, Anhui Province and the other in Lidu Village (LDC), Xishui County, Huanggang City, Hubei Province (Fig. 1). It grows in wetlands and mudflats along the Yangtze River, at elevations between 7 m and 13 m. This characteristic results in making R. daguanensis a well-defined obligate wetland indicator in its native area.	en	Zhang, Wei, Xiang, Xiao-Yan, Han, Ting-Shen, Shao, Jian-Wen, Zhao, Kai (2025): Rorippa daguanensis (Brassicaceae), a new species from eastern China.
