Identification of archaeobotanical Pistacia l. fruit remains: implications for our knowledge on past distribution and use in prehistoric Cyprus

Abstract

Pistacia spp. remains are common finds among archaeobotanical assemblages in prehistoric sites in Southwest Asia, both in the form of endocarps and charcoal remains. However, in the absence of a systematic study of the fruit morphology, the archaeobotanical remains of Pistacia cannot be identified to the species level and this deprives us of important information on their past geographical distribution and uses. This paper presents a comprehensive study of morphological and traditional morphometric characteristics of modern endocarps of six Pistacia species indigenous to Southwest Asia: P. atlantica Desf., P. eurycarpa Yalt., P. khinjuk Stocks, P. lentiscus L., P. terebinthus L. and P. vera L. The observation of recurring morphological features that were shown to remain stable during experimental carbonisation allowed us to set up an identification key whose efficiency was tested through a blind test. The application of established identification criteria to archaeobotanical material from the Late Aceramic Neolithic site of Khirokitia-Vounoi in Cyprus, enables an in-depth discussion on the biogeography and use of Pistacia species in prehistoric Cyprus. Finally, the paper identifies directions for future research on a major plant resource of the past.
