List of Arceuthobium species

From Wikipedia, the free encyclopedia

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) 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]
