Corylus avellana (Hazel)
A smooth, 3-pored, grain with a sub-triangular polar view and sub-oblate equatorial view (Godwin, 1975). The surface sculpturing is faintly rugulate, with tiny scabrae on the ridges (Moore, et al. 1991) but usually appears smooth after preparation. The grain is very similar to Myrica gale (sweet gale) and the two are difficult to separate (Edwards 1981), often shown on pollen diagrams as a composite Coryloid curve. Myrica is more robust with a thicker exine and more pronounced pores.
