Systematics Section/ASPT GAWHARI, AHMED [1], JURY, STEPHEN [1], CULHAM, ALASTAIR [1]. Using DNA sequences to investigate the phylogenetic relationships between Arbutus pavarii endemic in Libya and the closely related Canary Islands and Mediterranean species. Four species of the genus Arbutus occur in the Canary Islands and Mediterranean region, from North Africa to the Middle East. Arbutus pavarii, endemic to Libya has not always been treated as a distinct species. The approach of DNA barcoding has been used to help establish whether the species is distinct from it is Old-World congeners. All Arbutus specimen were sampled from authenticated herbarium material of the University of Reading Herbarium (RNG). Direct sequencing of DNA fragments of regions from cpDNA psbA-trnH and nrDNA internal transcribed spacer ITS was used to generate unofficial barcodes and for phylogenetic analysis. Bayesian Inference (BI) has been used for phylogenetic placement of Arbutus pavarii and the presence, or absence, of a barcoding gap for the species is discussed. Broader Impacts:
