Sample note
Plant identity was verified by Mr. Lin Ma (Institute of Materia Medica, Beijing 100050, China). A voucher specimen (No. ID-S-2385) was deposited at the herbarium of the Department of Medicinal Plants, Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100050, China.NOTE. There are 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.
