Correction of collection number errors in the protologues of twenty-three names of Chinese vascular plants

Examination and collation of Chinese type specimens from the University Herbarium, University of California, the Harvard University Herbaria and the William and Lynda Steere Herbarium of New York Botanical Garden led to the discovery of errors in the designation of type specimens in the protologues of several names. Following Article 9.2 of the International Code of Nomenclature for algae, fungi, and plants (Shenzhen Code, 2018), typographical errors in the citation of collection numbers in the protologues of 23 Chinese vascular plants were corrected.
