The historical relics in Chongqing Natural History Museum: An annotated checklist of original materials for 37 names of Chinese seed plants

A catalogue of type specimens deposited at the herbarium of Chongqing Natural History Museum (CQNM) is carried out. A total of 62 specimens belonging to 56 gatherings concerning 37 valid published names in 23 families of Chinese seed plants are documented as original materials. They include seven isotypes, 21 syntypes, of which 16 of them are isolectotypes and 34 paratypes. A checklist of the 37 names is presented with annotations on the typification, authorship citation, type localities and other taxonomic issues. Eight names were lectotypified, and one name's second-step lectotype is proposed. Additionally, Distylium lanceolatum Chun, which is invalid pending for further study, and which has long been treated as a synonym of D. dunnianum H.Lev., is listed after the 37 names.
