In this study, the species list of Corydalis from China(526 species)was firstly obtained. Of them, a total of 1 894 type specimens from 395 species were obtained by searching the JSTOR, GBIF and CVH databases. Then some key information, such as the resource type, herbarium, collector, type locality and collection date, were retrieved and analyzed. Our results showed that there were about five type specimens of Corydalis in average. These specimens were preserved in the 80 herbaria of abroad, and more than 85% of them were collected by foreign collectors. In the future, we should further focus on the normalized arrangement and the procedure of digitization of type specimens of Corydalis.]]> 2023/12/21 17:17:12 1, WANG Jing¹, FU Zhixi², LIU Yanyan^1*, LI Jiamei^3*]]> CAO Jialiang¹, WANG Jing¹, FU Zhixi², LIU Yanyan^1*, LI Jiamei^3* 4true Corydalis DC.(tribe Corydaleae, subfamily Fumarioideae, family Papaveraceae)was recognized as one of the largest and most taxonomically challenging genera in the world.

The samara, whose shape resembles the gold ingot of ancient China, is a unique oil tree species in China. In order to systematically study the geographical distribution and resource characteristics of A. truncatum in China, the geographical distribution pattern and resource characteristics of the main distribution areas of A. truncatum were analyzed by investigating the collections and existing literature of major digital herbarium at China and abroad. The results were as follows: A. truncatum was mainly distributed in 27 provinces regions/cities in Northeast and North China based on the 1 193 collected specimens. There were differences in leaf and fruit morphology in different regions, and the average fruit diameter of samples collected in Shaanxi Province was significantly larger than that in other regions. The collection place, collection time and other information of some of the samples were incomplete, and a few samples were incomplete due to improper collection or management. This paper provides a new idea and approach for studying the resource distribution of distinctive oil plants by using digital specimen resources.]]> 2023/12/21 17:17:12 *, ZHOU Xiaoxue, WANG Han, LIU Tao]]> CAO Yuxia, LIU Na^*, ZHOU Xiaoxue, WANG Han, LIU Tao 2true 2023/12/21 17:17:12 1,2, LIU Ende², CHEN Jiahui^2*]]> XU Zhoufeng^1,2, LIU Ende², CHEN Jiahui^2* 1true
