List of Arceuthobium species

Recently the number of species within the Arceuthobium has been reduced from 42 to 26. ^[1] The structure of the subgenera and sections follows Nickrent et al. (2004) ^[1] 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 ^[2]
