January 2017, the taxonomy of Juniperus sabinoides is not a valid name and the common name, location and protein matches Juniperus ashei, Jun a 1. There were only 5 amino acids described for Jun s 1 and they match segments in the Pectate lyases in Jun a 1 and Jun v 1. Therefore the Jun s 1 name is moved to Jun a 1 as a synon. in the WHO/IUIS database.
