Note:— Rubus delavayi was described by Franchet (1890), who provided the following information: “ Yunnan: in silvis supra Che-tong prope Tapin-tze et in calcareis montis Pi-ious-se; fl. 11 Jun. 1883 (Delavay 2562)” as the type in the protologue. Tropicos (2022) lists “ G. Forrest 129 ” kept in E as the type, with reference to the Flora of China ( Lu & Boufford 2003). This usage of “ G. Forrest 129 ” is not part of original material, and should be considered a mistake, thus it cannot be selected as lectotype that should be corrected for “ Delavay 2562 ”. According to Stafleu and Cowan (1976), Franchet worked at P and Delavay’ specimens were deposited in K, P and PC. We locate 3 duplicate specimens, deposited in P (barcode 00755222, 00755223, and 00755224), and all the specimens have Delavay’s annotation and are well preserved. The two sheets in P (barcode 00755222 and 00755223) bears the locality “ Yunnan, Ma eul chan”, and “ Yunnan: au Mont Pi-iou-se, au-dessus de Ta pin tze, près Tali”, as well as without collector number, so it cannot be selected as lectotype. We designate the blooming specimen “ Delavay 2562 ” in P (barcode 00755224) as the lectotype (Art. 9.12 of ICN). The selected sheet is complete and bears the same locality and date that fully correspond with the protologue.
