A contribution towards resolving the nomenclature of Citharexylum (Verbenaceae) II: remarks on implicit typifications and lectotypification of names linked to Mesoamerican taxa

Abstract

During ongoing taxonomic studies in Citharexylum (Verbenaceae), sixteen names were found in need of typification or typification remarks. As a result, six names (C. brachy-anthum, C. danirae, C. flabellifolium, C. lucidum, C. rugendasii and C. tristachyumf. urbanii) are here lectotypified. Furthermore, remarks on implicit typifications by Harold Moldenke for another ten names (C. altamiranum, C. berlandieri, C. hexangu-lare, C. macradenium, C. ovatifolium, C. pauciflorum, C. pterocladum, C. recurvatum, C. schulzii and C. stenophyllum) are provided.
