Una nueva especie de Bursera (Burseraceae) del Este de la Región de Los Cabos en Baja California Sur, México

[摘要] Background and Aims:Intensive fieldwork along the shore of the East Cape Region in the Baja California Peninsula by the authors has resulted in the discovery and publication of some new species for the Mexican flora in recent years. Methods:An additional novelty found was a tree considered at first to beBursera microphylla,but a more detailed inspection showed the leaflets to be few in number and broadly obovate-elliptic. These and additional differences of the leaves and flowers warrant recognition of this plant as a new species. Key results:We here describe and illustrateBursera exequielii(Burseraceae), which belongs to sectionBurseraand we discuss its morphological relationship withB. microphylla , from which it differs mainly by the number, form and size of the leaflets. Conclusions:The only known population is threatened due to the mega-touristic developments in the zone.
