    History and curiosities: 

    The scientific name, Platanus x hispanica, consists of the genus name Platanus, coming from the Greek πλατανοϛ, "plane tree", one "x" indicating that it is a hybrid and the Latin term hispanica, "Hispanic, from Hispania", in allusion to the origin of the exemplars which provided the material to make the first description of the species, in 1770.

    This species origin would be a hybridation between the P. orientalis (oriental plane) and the P. occidentalis (American sycamore), happened in the 17th c. in Spain.
