The Fetter-bush, Andromeda polifolia L., contains andromedodextrin, a narcotic poison, in its leaves. Pam-mel states that it has been known to poison sheep. It is a shrub six inches to two feet high, growing in bogs throughout the country. Its small, oblong, leathery leaves have strongly revolute margins, and are white woolly beneath. The drooping umbels each contain only a few delicately coloured pink flowers.
