Hooker and T. Thomson’s collections of Gentiana elements (an unnamed species as Gentiana sp. n. 41) from Sikkim Himalaya, India , described a new species Swertia hookeri C.B.Clarke and cited specimens as “ Sikkim Himalaya, alt. 12-13,000 ft. ; Lachen & Choongtam, J.D.H., King ”. Ho & Liu (2015: 165) , regarding the type of the name S. hookeri C.B.Clarke , cited “J. D. Hooker s.n. (CAL – holotype , not seen; GH!, K! – isotypes)” which do not stand on any ground according to the rules of ICN (vide Art. 7.11, 9.1, 9.3 & 9.10) even in this case as well. Nine original specimens associated with this name were traced ( 1 in CAL [ CAL0000018334 ], 6 in K [ K000854378 , K000854379 , K000854381 , K000854383 , K000854382 , K000854384 , digital images!], 1 in L [QRcode L.2693413] and 1 in P [ P00524815 ]) possessing authentic labels. However, we have been unable to locate any specimens from GH. Amongst the traced original specimens, CAL0000018334 ! bear original notes written on the sheet and agrees well with the protologue; hence selected here as the lectotype .
