Habenaria delavayi Finet (1901: 527) .

Type:— CHINA. Yunnan, Mo-so-yn, August 1888, Delavay 4560 [lectotype designated here: P ( P00405972 image!); isolectotypes: P ( P00405970 image!, P00405971 image!)] ; Yunnan, Ta-pin-tze, 2000 m, July 1886, Delavay s.n. [syntype: P ( P00405973 image!)]; Lan-kong, 3000 m, July 1885, Delavay 1688 [syntypes: P ( P00405974 image!, P00405975 image!)] ; Yunnan mountains, July 1897, Ducloux 310 [syntypes: P ( P00426060 image!, P00426059 image!), K ( K000796936 image!), LE ( LE01012224 image!)] .

Notes:— This species is endemic to China with distribution limited to Sichuan, Yunnan and Guizhou provinces along the elevation range of 1500–3200 m. Finet (1901) named Habenaria delavayi in honor of Pe ̀re Jean-Marie Delavay (1834– 1895). In the protologue, Finet mentioned the exsiccata from Yunnan — Delavay s.n. (July 1886), Delavay 1688 (July 1885), Delavay 4560 (August 1888) and Ducloux 310 (July 1897), without designating any of them specifically as type, thus consequently all these vouchers belonging to the exsiccata are syntypes ( ICN, Art. 9.6). While searching for these specimens, a set of all of these specimens was located at P: Delavay 4560 with 3 duplicates, Delavay s.n. single specimen, Delavay 1688 with 2 duplicates and Ducloux 310 with 2 duplicates; moreover, duplicates of Ducloux 310 were also found at K and LE. However, duplicates of other syntypes could not be traced elsewhere but P. Of the 3 exsiccata of Delavay 4560 at P, one of them ( P00405972 ) bears the label of ‘type’ and the other two ( P00405970 , P00405971 ) are labelled as ‘isotype’, but referring to the protologue, there is no such specifically designated specimen; following McNeil (2014), this does not infer as the holotype designation, hence it must be an error and thus demands clarification. Consequently, Delavay 4560 specimen with barcode no. P00405972 is designated here as the lectotype, the other two duplicates thus became isolectotypes .
