Scolopendrium feu lingua cervina Pharm. Edinb. Lingua cervina officinarum C. B. Phyllitis Gerard. Asplenium Scolopendrium Linn. Harts-tongue: a plant with long, uncut, narrow bright green leaves, set on long hairy pedicles, and nipt at the bottom: it has no stalks or manifest flowers; the seeds are a fine dust, lying in large, rough, brown, transverse streaks on the backs of the leaves. It is peren-nial, and found green at all times of the year, in moist, shady, stony places.

The leaves of harts-tongue stand recommended as aperients and corroborants, in ob-structions of the hypochondriacal viscera, laxities of the intestines, and some disorders of the breast: they have been chiefly used in apozems and in-fufions, along with maidenhair, spleenwort, and other plants of the same kind, with which they appear to agree in virtue. To. the taste they are slightly roughish and sweetish: with solu-tion of chalybeate vitriol, they strike a blackish colour. When fresh, they yield, on being rubbed or bruised, a faint unpleasant smell, which' in drying is in great part dissipated.
