The origin and natural range of the Stone pine (Pinus pinea L.) has been questioned for more than a century. In this work, we focus the investigation on one of the most important and controversial regions, viz., the Iberian Peninsula and, specifically, the Huelva and Cadiz populations in Andalusia, one of the most representative population cores. Although some authors maintain that it is an autochthonous Iberian species, most of them consider it to be exotic. From this idea, many works have been done and a sintaxonomic scheme has been created, which is accepted by the majority of the scientific community, not including Pinus pinea, nor its formations, since they are considered as man-induced forest crops. However, Stone has been present for several thousand years in the Iberian Peninsula and in the territory studied, as several paleobotanic and historical data show, proving that Pinus pinea is an autochthonous species of this region. This is a clear consequence to the field of geobotany, since -- at least -- the Stone pine woodlands from the Iberian Southeast must be considered as communities predominated by an autochthonous species that must be included in the sintaxonomichal schemes.
