Summary
A survey was conducted of the frequency of the cyanogenic form of Lotus corniculatus within a range of populations on Mainland, Orkney. Most populations were found to contain a high percentage of cyanogenic plants. Two exceptions were at Yesnaby and on the links at Birsay. A detailed study of populations on and off the Birsay Links revealed a highly significant quantitative association between soil moisture content and the frequency of the cyanogenic form.
