Esquirol920(barcode E00010567!, isolectotype: A00112778). [Image available at https://data.rbge.org.uk/herb/E00010567].  Note:—Léveillé (1910) mentioned the following locality: “Kouy-Tchéou, Typus: Tchen-Fong, Juill. 1905, 1906, J. Esquirol 525 & J. Esquirol 894” in the protologue when describing  Rubus calycacanthus, but since then, no author has designated a lectotype, even inadvertently (Art. 7.11 of ICN). According to Stafleu and Cowan (1979), all of the Léveillé’s type specimens have been purchased by E in 1919. We locate four duplicate specimens, one of the collection “1905, J. Esquirol 525” deposited in A (barcode 00112778) and E (barcode 00010566), while another collection “1906, J. Esquirol 894”, deposited in A (barcode 00112779) and E (barcode 00317762). All these collections should be regarded as syntypes( ICN, Art. 9.6). Hence, it is necessary to select one of them as the lectotype(Art. 9.12 of ICN). Hence, we designate here the sheet “ J. Esquirol 525” kept in E (barcode 00010566) as the lectotypesince it is morphological complete with the presence of stem, leaves, flower, and inflorescence that fully correspond with the protologue. For  Rubus calycacanthusvar. buergerifolia, Léveillé (1910)provided two localities: “Kouy-Tchéou, Typus: Tchen-Fong, J. Esquirol 920” and “Houa-Kiang, 3 juin 1904, J. Cavalerie 2175”, but did not indicate the holotypespecimen. We locate both the collections ( syntypes), deposited in E, from which a lectotypecould be chosen (Art. 9.12 of ICN). Therefore, we designate the sheet “ J. Esquirol 920” in E (barcode 00010567) as the lectotype.The selected sheet is a complete and well-preserved specimen that displays all the morphological diagnostic traits in agreement with the protologue. 3890546316 1905-07-01 J.
