. A manual of weeds : with descriptions of all the most pernicious and troublesome plants in the United States and Canada, their habits of growth and distribution, with methods of control . Weeds. COMPOSITAE {COMPOSITE FAMILY) 501 COLTSFOOT Tussilago Fdrfara, L. Other English names: Coughwort, Ginger Eoot, Clayweed, Dove- dook, Horsehoof, Foalfoot. Introduced. Perennial. Propagates by seeds and by rootstoeks. Time of bloom: Early April to June. Seed-time: May to July. Range: Nova Sootia to Minnesota, southward to Pennsylvania and Ohio. Habitat: Moist clay soil; thin pastures, alluvial banks, along brooks and roadsides. Scapes slender, springing from thick succulent rootstoeks and' appearing before the leaves, at first but a few inches high, bearing reddish scales that are slightly white- woolly, and holding erect a single flower- head about an inch broad, golden yellow; the flowers have the odor of honey and the pollen furnishes bees with early prov- ender. Ray-florets in several rows, pistillate and fertile; disk-florets perfect but sterile, the corolla tubular and five- cleft ; after a head has been fertilized the stalk rapidly elongates to a foot or more in height, and the head is so bowed that it is protected from rain by the bell- shaped involucre until the achehes have formed, when it is again erected and opens out a ball of downy pappus, whiter and more floss-like than that of the dan- delion. Near the end of the flowering season the leaves appear, rising from the rootstoeks, nearly round, heart-shaped at base, slightly lobed and toothed, thick, smooth, and dark green above but white- woolly underneath, with petioles about as long as the blades; they continue to grow all summer, becoming often six or eight inches broad.
