Remarks on the type designation of two names in Rhamnus (Rhamnaceae)

PEDRO PABLO FERRER-GALLEGO, EMILIO LAGUNA

Abstract


The genus Rhamnus Linnaeus (1753: 193) (Rhamnaceae Jussieu 1789: 376) contains more than 100 species (Medan & Schirarend 2004, Hauenschild et al. 2016) distributed in the temperate to tropical regions (North America south to Guatemala, temperate South America, Europe, Africa and Asia). Although this genus includes more than 700 published specific and subspecific names, several of these names represent local variations of more broadly distributed taxa (Grubov 1949, Tutin 1968, Johnston 1975, Johnston & Johnston 1978, Richardson et al. 2000a, b, Ruiz de la Torre 2006, Hauenschild et al. 2016).
