Roman and Medieval crops of the Iberian Peninsula: a first synthesis of seeds and fruits from archaeological sites

This paper presents an overview of the current state of research on Roman, Late Antique and medieval agriculture in the Iberian Peninsula through the study of archaeobotanical samples (seeds and fruits) collected on a large number of rural and urban sites spread throughout Iberia's geography. It includes published and unpublished data. The plant taxa of economic interest are grouped into various categories: cereals, cereal chaff, legumes, domesticated fruits, oil/fibre plants, condiments and spices, and wild species. According to the data, naked wheats and hulled barley are the dominant cereal species throughout the Iberian Peninsula. There are, nonetheless, particularities like the prevalence of hulled wheats (mainly emmer and spelt) in the North-west. Cultivated fruits also show a great diversity, and new species such as Morus nigra or Prunus armeniaca appear for the first time in the archaeobotanical record. There are also novelties regarding herbs and spices.
