Introduced Dioscorea spp. starch in Lapita and later deposits, Vao Island, Vanuatu
Horrocks M, Bedford S. 2010. New Zealand Journal of Botany 48, 179-183.
Abstract
Analysis of deposits at a Lapita site in Vanuatu revealed putative starch grains of Dioscorea nummularia in c. 2800-3100 cal BP layers and of D. pentaphylla in a c. 2000 cal BP layer suggesting local cultivation of these tuberous crops. The Dioscoreaceae are a new addition to the introduced cultigens thus far directly identified for prehistoric Vanuatu.
