Note:—In the protologue, Focke (1891) provided the following locality information: China, Prov. Hupeh, (Dr. A. Henry 6849) when he described Rubu pileatus , but did not indicate the herbarium where the type preserved. Tropicos (2022) lists “ E. H. Wilson 813 & G. Giraldi 5224 ” as the type, with reference to the Flora of China ( Lu & Boufford 2003). Lu & Boufford (2003) did not cite any type specimen, and “ E. H. Wilson 813 & G. Giraldi 5224 ” are not part of the original materials and should be disregarded. It is well known that Focke’ original type materials were deposited in A, B, BORD, BR, BREM, HAN, K, LE, W and duplicate specimens in M, MO and NY ( Stafleu & Cowan 1979). We located eight duplicate specimens, deposited in A (barcode 00040703), BM (barcode 000622274), GH (barcode 00112776), K (barcode 000737825), NY (barcode 00429709), P (barcode 00755319), and US (barcode 01107713). All these collections should be regarded as syntypes (Art. 9.6 of ICN). Among the available collections, the original materials of “ A. Henry 6849 ” kept at K (barcode 000737825) selected as lectotype (Art. 9.12 of ICN). The selected sheet is complete and well preserved specimens that fully correspond with the protologue.
