SUMMARY
A total of 694 plants of Trifolium repens were collected in 17 samples to investigate the effect of altitude on the frequency of cyanogenic plants; the area chosen for this purpose was North Wales, with altitudes ranging from 100 to 1600 feet. A significant decrease in frequency of AcLi plants was observed, lower values obtained in high altitudes; the calculated regression coefficient was −0·01938 (in angular measure), with P<0·001.
