Dendropanax arboreus have been considered a high phenotypic variable species and the name applied to many different entities from Mexico and the West Indies to Brazil and Bolivia, from sea level up to 3200 m. A circumscription of D. arboreus based on the West Indies populations is proposed. This is the first step in order to delucidate how many tax...

Guedes et al.1 argue that eponymous scientific names, despite their long tradition in biology, have no place in the modern world. They want to erase eponyms assigned to species in the past and want scientists to stop naming new species after people. Both of these proposals would hurt science and disproportionately hurt science in the Global South —...

The urge to organise the world around us is an essential part of human nature. Naming and categorising enable us to store and access information ef ciently. The need to name and categorise extends to the natural world and, in particular, to living organisms. The science underpinning this area of knowledge is called Taxonomy, and is as old as humani...
