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.
