Lin, Yun, Bi, Hai-Yan, Sun, Jun & Sun, Qian, 2023, Correction of collecting number errors in the protologues of sixty-four taxon names from China, Phytotaxa 598 (4), pp. 271-282 : 276

30. Hoya hainanensis Merr.

(Asclepiadaceae) in Philipp. J. Sci. 23(3): 263. 1923.

TYPE:— CHINA. Hainan: Wuzhishan, Wuzhi Shan, May 1922, F. A. McClure 3221 (i.e. Canton Christian College Herbarium 9759) (syntype: PNH, destroyed, A 00076415 image!, A 00076416 image!) .

McClure 9759 was the only gathering cited in the protologue of the name Hoya hainanensis Merr. ( Merrill, 1923) . However, the collecting number on the label of the syntype specimen ( A 00076415 ) is 3221, while its herbarium number is Canton Christian College Herbarium 9759. Thus, the collecting number cited in the protologue is to be corrected.
