The discovery of three bronze age cist burials at Ashgrove, Fife, was unusual in revealing highly decomposed macroscopic plant debris in cist I, which was excavated by Professor R. J. Adam, Mrs Mary Adam and Professor L. H. Butler. Miss A. Henshall (1964) states that the liberal clay luting of the side slabs and cover of cist I had been so effective as to keep the interior dry and free of soil. She also reports that 'Over the skeleton and cist floor there was a thin deposit of black crumbly matter which formed a deep deposit nearly I ft across in the area between the forearms and upper arms, i.e., in the vicinity of the chest' (p. 167) (PL. xva). Miss C. A. Lambert (now Mrs C. A. Dickson), in an appendix to Henshall's paper, found that 'The plant material consisted of abundant dicotyledonous leaf fragments, bark, twigs, wood charcoal (two tiny fragments), plant tissue with crystalline copper salts adhering to it and fairly abundant sphagnum moss. The leaf fragments were several layers thick but their poorly preserved condition prevented their separation and identification.
