资源简介：
A single seed was collected from a trench containing organic-rich silts interbedded with sand layers deposited by tsunamis in the floodplain of the Tirua River, Chile. The seed was found below a dark brown agricultural soil that had been formed into multiple symmetrical berms and furrows spaced 1.5 m apart. This agricultural layer was buried by the fourth tsunami sand layer (Sand D) down from the top of the trench. Wood and charcoal from Sand D yielded radiocarbon dates that range from about AD 1400-1600. The seed was submitted for identification and radiocarbon dating.
