Tussilago, from Latin iussis, a cough, for which the plant is a popular remedy, is a European plant now wild along brooks and damp roadsides, near dwellings, and in pastures. It is not very common. The weed is chiefly met with on damp, stiff clays or moist, chalky clays. Seeding should be prevented; and the plant needs special attention because of its habit of flowering- before the leaves appear, the reverse of what usually happens. The plant may be exterminated in one or two seasons by cutting off the leaves as soon as they appear. Draining is an efficient remedy. When the plant is thoroughly established, it often sends its roots to a depth of two or three feet. ^ Coutsfoot I ussilagu Far/ara. (L) FIREWEED. Erechtites hieracifolia, (Raf.).
