One letter, four names, two taxa: clarifying the Eriocaulon (h)elichrysoides (Eriocaulaceae) confusion
摘要
Eriocaulon and Paepalanthus are the most speciose genera of Eriocaulaceae, presenting many nomenclatural and taxonomic problems. In this manuscript, we clarify the intricate nomenclatural and taxonomic confusion regarding the names Eriocaulon elichrysoides Bong. and Paepalanthus helichrysoides Kunth, as well as all homotypic associated names corresponding to two distinct entities. We provide complete species headings by evaluating all names, protologues, and type specimens. A discussion of the names’ histories and uses is also included, highlighting some names that were forgotten or avoided in the past. We also select a lectotype for Paepalanthus helichrysoides Kunth.
