Abstract
A macrofossil of the alpine bolster plant Donatia novae-zelandiae was found in the King River Valley, approx 230m above sea level in central W Tasmania. The fossil was in situ on a palaeosol that appears to have formed immediately prior to the late Last Glacial Maximum. An age of 21 180 + 370yr BP was established by radiocarbon dating. Pollen and present day distributional data suggest that the tree line was then at least 750m lower than at present, implying a temperature depression of approx 4.5oC. Scanning electron-micrographs and photomicrographs of the extant and fossil bolster species are presented.-Authors Recent palaeosol Glacial Maximum
