Lectotype.

(designated here; first-step designated by Sealy 1958: 163): China. Yunnan: Ta long tan, 10 October 1889, Delavay s.n. (P01903507!; its image is available at https://science.mnhn.fr/institution/mnhn/collection/p/item/p01903507).

Notes.

Two gatherings, Delavay s.n. and G. Forrest 430, were cited in the protologue ( Diels 1912: 284), so they are syntypes of T. yunnanensis (Art. 9.6 of the ICN). When Sealy (1958: 163) cited " Delavay 15 Oct. 1889 (P, type)", his lectotypification must be accepted, but may be considered as the first-step (Art. 9.17 of the ICN) because three specimens of Delavay’s collection matching the description of T. yunnanensis were found at P (P01903507, P01903508 and a single specimen consisting of two sheets: P06614716 [1/2] & P06614717 [2/2]; Art. 8.3 of the ICN, also see Ex. 7). However, the three specimens of Delavay s.n. were all collected on 10 October 1889 and two of them, P01903507 and P01903508, bear Pitard’s handwriting " Thea Camellia yunnanensis sp. n.", so the date of collection recorded in the protologue, "15 October 1889", is probably incorrect and the correct date is 10 October 1889 which was recorded on the labels. Specimen with barcode P01903507 bears a drawing of a dissected flower and is designated above as the second-step lectotype of T. yunnanensis (Art. 9.17 of the ICN).
