Boswellia neglecta (Ogaden frankincense), native to Ethiopia and Kenya, yields a resin essential oil characterised by a-pinene, a-thujene, and p-cymene as dominant volatiles, a profile analytically distinct from the more commercially traded Boswellia species. GC/MS-based volatile profiling has placed B. neglecta within a taxonomically informative cluster of rare Boswellia species, with its resin volatiles and hybridisation data contributing to understanding of chemotaxonomic relationships within the genus.^[1]
