Abstract： Type specimen is the original specimen from which a new species description is created, and is very important to stabilize the scientific name of the species. Corydalis DC. (tribe Corydaleae, subfamily Fumarioideae, Papaveraceae) was recognized as one of the largest and most taxonomically challenging genera in the world. 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 are 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.

Abstract： Centratherum Cass., a newly naturalized genus of the family Asteraceae from Southeast Asia, was recorded in northern Thailand and southwestern China. Centratherum punctatum Cass. subsp. fruticosum (S. Vidal) K. Kirkman ex Shih H. Chen, M. J. Wu & S. M. Li, the only one representative subspecies of this genus from mainland of Southeast Asia, is described and illustrated based on the specimens. C. punctatum subsp. fruticosum can be distinguished from the other taxa of this genus by its leaf blade rhombic to elliptic, leaf margins irregularly serrate, leaf apex broadly acute, and phyllaries indurate at base and not awned. Its distribution map is provided and the possible dispersal pathway is discussed.
