List of Arceuthobium species
Recently the number of species within the Arceuthobium has been reduced from 42 to 26. The structure of the subgenera and sections follows Nickrent et al. (2004) who resolved the phylogeny of the genus using nuclear ribosomal internal transcribed spacer (ITS) sequences and chloroplast trnT-L-F sequences. Much of the work in Arceuthobium systematics was undertaken and compiled by Hawksworth and Wiens
