64389E585BC85DF9B7D5F039D77ED660.taxon	diagnosis	Diagnosis. Rubus semiplenus is most closely related to Rubus hirsutus Thunb., but clearly distinguished morphologically from the latter by its habit herbs or dwarf subshrubs (vs. shrubs in R. hirsutus), stems villous hairs (vs. soft and glandular hairs), leaves simple (vs. imparipinnate, 3 – 5 foliolate), suborbicular (vs. ovate or broadly ovate), sepals ovate-orbicular (vs. ovate-lanceolate or triangular-lanceolate), petals dicyclic, semi-doubled flowers, with 10 – 12 (vs. petals 5).	en	Wang, Ting-Ting, Li, Ming-Hong, Kuang, Dai-Yong, Xia, Jiang-Lin, Wang, Qiu-Ping, Wang, Huan-Chong (2025): Rubus semiplenus (Rosaceae), a new species with naturally occurring semi-double flowers from Hunan, China.
