Palms are less common, particularly Borassus flabellifer, which becomes rare.
Trema, Celtis and Macaranga all increase to reach maxima at 40-50cm depth, while Borassus flabellifer reappears in the pollen record at 40cm depth (absent from the record since 100cm depth).
A number of useful plants are apparent, particularly Celtis tetrandra-type, typically a timber tree (Po 2003) but also with edible fruit, and the palmyra palm, Borassus flabellifer.
