It is therefore often overrepresented in littoral accumulations. This may cause difficulties in interpreting oscillating pollen curves. But it may also be useful (1) to estimate the period of terrestrialisation of a basin, (2) to detect hiatuses and (3) to reconsider pollen-zone boundaries that were based on crossings of pollen curves if one of the pollen types is saccate.en500 - Science::580 - Plants (Botany)book_section10.48350/157999
