S ummary A series of clays and muds underlying head deposits, exposed in a cliff section at West Angle, Dyfed, has been subjected to pollen analysis. Four pollen assemblage zones are described, all being dominated by temperate forest taxa, but with Pinus, Picea and Abies all present in some quantity. Forest disturbances are evident within the profile, in which light‐demanding taxa such as Fraxinus, Juniperus and Corylus become more frequent, as do many herbaceous types. Possible causes of these disturbances are considered, the most likely being local flood catastrophes. It is not possible fully to correlate the pollen sequence with other British and Irish interglacials, but certain features compare closely to some Hoxnian diagrams of eastern England. These are: (i) the presence of Abies , (ii) the occurrence of Picea through the entire profile, (iii) the consistent presence of Tilia in the middle two zones and (iv) the lack of Carpinus maximum.
