A contribution towards resolving the nomenclature of Citharexylum (Verbenaceae): typification of names linked to South American taxa

Abstract

During ongoing taxonomic studies in the genus Citharexylum (Verbenaceae), twenty names were found in need of typification or typification clarifications. Fourteen names (C. andinum, C. herrerae, C. ilicifolium, C. kunthianum, C. laetum, C. myrianthum var. acuminatum, C. myrianthum var. rigidum, C. pernambucense, C. poeppigii, C. quercifolium, C. solanaceum, C. solanaceum var. macrocalyx, C. surrectum and C. weberbaueri) are here lectotypified, and epitypes are selected for three names (C. herrerae, C. kunthianum and C. pernambucense). Neotypes are designated for the names C. berteroi, C. broadwayi and C. coriaceum. Furthermore, updates and supporting information for three names already typified by Harold Moldenke (C. macrochlamys, C. punctatum and C. subthyrsoideum) are provided.
