*Most of the work described in this paper was done while the author was employed at the Macaulay Institute for Soil Research in Aberdeen. I wish to acknowledge the help given by numerous conversations with Dr A. Muir. The name proposed is derived from the Carden Wood, Aberdeenshire, near which the soil sample (No. BB63) was taken.
