Palmatiboea gamosepalus F. Wen & Q. Fan 2024, comb. nov.

Palmatiboea gamosepalus (Xin Hong & F. Wen) F. Wen & Q. Fan comb. nov. ≡ Didymocarpus heucherifolius var. gamosepalus Xin Hong & F. Wen, in PhytoKeys 128: 34. 2019. ≡ Palmatiboea heucherifolia var. gamosepala (Xin Hong & F. Wen) F. P. Liu & Y. Z. Wang, in Journal of Systematic and Evolution doi: 10.1111/jse.13124: 13. 2024. Type. China • Guangxi Province, cultivated in the nursery of Gesneriad Conservation Center of China (GCCC), introduced from north of Guangdong Province: Pingyuan County, Meizhou City, growing in rocky crevices at the foot of a calcareous sedimentary rocky hill. 22 February 2019, flowering, WF 20190222-05 (holotype: IBK!; isotype: AHU!) Notes. We have noticed that several newly revised species and genera names use the name abbreviation of the corresponding author Yin-Zheng Wang as “ Y. Z. Wang, ” such as the names of the two new genera, Palmatiboea F. P. Liu & Y. Z. Wang and Hequnia Y. Z. Wang & F. P. Liu in Liu et al. (2024). However, the name abbreviation “ Y. Z. Wang ” originates from Prof. Wang Yun-Zhang, a renowned Chinese mycologist and plant pathologist, whose name abbreviation first appeared in the 1980 s when he described 15 new species of Rust Fungi (Wang et al. 1980). Prof. Wang Yin-Zheng, on the other hand, first published a new taxon in the mid- 1990 s, Whytockia purpurascens Yin Z. Wang and W. hekouensis Yin Z. Wang (Wang 1995). When W. purpurascens and W. hekouensis were published, the author’s name abbreviation was mistakenly written as “ Y. Z. Wang. ” However, the abbreviation “ Y. Z. Wang ” for Prof. Wang Yun-Zhang appeared 15 years earlier than that of Prof. Wang Yin-Zheng when describing new taxa (IPNI 2024); therefore, for the aforementioned nomenclature, including the new genera Palmatiboea and Hequnia and their respective species. Additionally, there are quite a few revised species of Gesneriaceae that incorrectly use “ Y. Z. Wang ” to refer to Prof. Wang Yin-Zheng. For example, Petrocosmea shilinensis Y. M. Shui & H. T. Zhao var. changhuensis T. F. Lü & Y. Z. Wang should be changed as P. shilinensis var. changhuensis T. F. Lü & Yin Z. Wang (Li et al. 2020), and so on. In summary, the correct name abbreviation should be “ Yin Z. Wang, ” not “ Y. Z. Wang ” among the many revised species epithets of Gesneriaceae mentioned above.
