摘要

Rubus yingjiangensis Huan C. Wang, a new species in Rosaceae from Yunnan, south-west 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.
