2. Gentiana phyllocalyx C.B. Clarke (1883: 116) View in CoL .

Lectotype (designated here):— INDIA. “ Sikkim Himalaya , alt. 13‒15,000 ft. ” ( CAL, barcode CAL0000018107 About CAL ! ( Fig. 2 View FIGURE 2 ). Isolectotypes: K, barcode K000872001 , three individuals beside the colour plate on the sheet above barcode of this number, digital image!; L, QRcode L.2695807, digital image!; P, barcode P00506810 , P00506811 , P00506816 , digital images!). Residual Syntypes: INDIA. Sikkim: “Kankola and Lachen, J.D. H ” ( K, barcode K000844000 , K000872002 , digital images!) .

— Clarke (1875) described an unnamed species of Gentiana (sp. no. 26), which he mentioned being distributed under the name G. venusta Wall. by J.D. Hooker and Thomson (“sub nomine G. venusta, Wall. , ab Hook.f. et Th. distributa) collected from “ Sikkim ad 13,000 -15,000 ped. alt., coll. Hook. f. et Th. ”. Subsequently, he validated this unnamed species as G. phyllocalyx C.B.Clarke in The Flora of British India ( Clarke 1883) directly referring to his 1875 publication. Therefore the specimens (“ Sikkim ad 13,000 -15,000 ped. alt., coll. Hook. f. et Th. ”) cited in his 1875 publication are to be treated as original materials (vide Art. 9.4 Shenzhen Code), associated with this name along with the newly cited gatherings from “Kankola and Lachen” collected by J.D. Hooker.

Ho & Liu’s statement (2001: 233) “J. D. Hooker s.n. (K! – holotype; BM! GH! –isotypes)” regarding the types of the name Gentiana phyllocalyx C.B.Clarke and usage of the terms “ holotype ” and “isotype” do not stand on any ground according to the rules of ICN (vide Art. 7.11, 9.1, 9.3 & 9.10) in this case as well.

During our study, nine specimens were traced which were distributed by the name Gentiana venusta Wall. , of which six collected from Sikkim in between 13,000 -15,000 ft., and two particularly from “Kankola” and one from “Lachen”, all collected by J.D. Hooker. The specimen deposited in CAL (barcode CAL0000018107) is selected here as the lectotype for the name Gentiana phyllocalyx C.B.Clarke for having original remarks by C.B. Clarke regarding the characters how it differs from G. venusta and unambiguously corresponding with the protologue. No original specimen associated with the name Gentiana phyllocalyx C.B.Clarke could be traced in GH and BM; however, in BM one specimen (barcode BM001014679, digital image!) is located, which bears an annotation slip of T.N. Ho designated as the type of G. phyllocalyx f. lutescens , a name could not be traced, is not collected from Sikkim or by J.D. Hooker and therefore could not be treated as a type material for the former name.
