Rubus yingjiangensis Huan C. Wang, a new species in Rosaceae from Yunnan, southwest China, is described and illustrated. It resembles R. chaetophorus, but clearly differs from it by lacking glandular hairs, 12–18 cm long leaves cordate-auriculate at the base and abaxially tomentose, with the apex acuminate to long acuminate, hypanthium which is 0.5–0.7 cm in diameter, 0.8–1 cm long sepals, and 0.6–0.8 cm long petals. The names R. mallotifolius and R. sapaensis are treated as taxonomic synonyms of R. nigricaulis, which has almost been overlooked in modern taxonomic literature.
