Note:— Focke (1911b) cited two gathering “ A. Henry 6045 ” and “ Wilson s.n.” in the protologue when he described Rubus trianthus , but did not indicate the holotype specimen. In addition, no author has designated a lectotype, even inadvertently (Art. 7.11 of ICN). 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 four duplicate specimens, four specimen of “ A. Henry 6045 ” deposited in A (barcode 00040748), E (barcode 00010654), K (barcode 000737777), and US (barcode 00095494). However, we did not locate the specimen “ Wilson s.n. ” in any available herbarium. All these collections should be regarded as syntypes (ICN, Art. 9.6). Hence, we designate here the original materials of “ A. Henry 6045 ” kept in K (barcode 000737777) as lectotype (Art. 9.12 of ICN). The selected sheet is complete and well preserved specimens that fully correspond with the protologue.
