Prunus webbii

Prunus webbii is a species of Prunus found growing around the Mediterranean Sea, from Sicily, through Greece, Crete and the Aegean Islands, the Balkans and Anatolia, and possibly as far as Iraq or Iran. It is also found in certain areas of Spain and Northern Africa. A dense spiny shrub or small tree with extremely bitter seeds, it is thought to have contributed with some genes to the domesticated almond Prunus dulcis, although the extent of the contribution is debated and not yet fully understood.
