3CE6A311D76558F08E48E3565C0CE967.taxon	etymology	Etymology. The epithet ' silaniae' is coined to honour Prof. Si-Lan Dai, the famous horticulturist at the Beijing Forestry University. She is also the former supervisor of one of the authors, Prof. Xin-Xiang Bai. Meanwhile, one of the given names of Prof. Si-Lan Dai, namely ' Lan', shares the same pronunciation in Chinese with the color blue. Thus, the scientific name also hints at the bluish to purplish-blue corolla of this new taxon.	en	Zhang, Jin-Quan, Huang, Hong, Li, Mei-Jun, Huang, Mei, Li, Quan-Yuan, Zhou, Yu-Lu, Chen, Yi, Wen, Fang, Bai, Xin-Xiang (2021): Primulina silaniae sp. nov.
