Sample note
The leaves were obtained from Anhui Province in China. They were authenticated by Professor Jin-Cai Lu (Department of Traditional Chinese Materia Medica, Shenyang Pharmaceutical University. P. R. China. A voucher specimen is stored at the herbarium of the Department of Pharmacognosy, Shenyang Pharmaceutical University. NOTE 2. There are some conflicting views on the taxonomy of I. tinctoria (European woad) and I. indigotica (Chinese woad). I. indigotina was described for the first time by Fortune in 1846, and initially considered as a distinct species. Afterward, some taxonomists have classified it as a variety of I. tinctoria. Nowadays, I. indigotina is considered as a synonym of I. tinctoria [e.g. The Plant List, IPNI (International Plant Name Index), Tropicos]. (Speranzo et al. 2020). In this database, we use the names similarly as the authors.
