Comment:
an illegitimate, superfluous name (Madrid ICN Art. 52) for Pinus ponderosa subsp. benthamiana (Hartw.) Silba, which ought to have been adopted, as its basionym, P. benthamiana Hartw., was cited as a synonym\: it is not homotypic with subsp. benthamiana as a different type was designated (Madrid ICN Art. 7.5)
