“…Additionally, the identification of the source from which the pollen originates in such waste deposits is less straightforward than for macro remains, which makes the interpretation of the pollen assemblage more difficult. However, the few existing pollen analyses of such contexts do provide a lot of additional information on former plant use, which could mostly not have been obtained through the study of botanical macro remains (see for example De Clercq et al, 2007;Greig, 1981Greig, , 1982bGreig, , 1994Horrocks and Best, 2004;Knights et al, 1983;Kuijper and Turner, 1992;van Den Brink, 1988, 1989; van Haaster, 2008). This is not surprising as several useful plants, especially herbs and spices can only be recovered in the form of pollen because these plants are harvested before they produce seeds, or because only vegetative parts of the plants are used.…”
