SENECIO (the old Latin name used by Pliny, and derived from senex, an old man; alluding to the usually white, hair-like pappus). Groundsel; Ragweed. Including Adenotrichia, Brachyrhynchos, Cacalia, Cineraria (in part), Farfugium, Gynoxys (in part), Jacobaea, Kleinia (of Haworth), Ligularia, Pericallis, Senecillis, and Syneilesis (Cacalia, Cineraria, and Ligularia, are, however, for garden purposes, kept distinct in this work). ORD. Compositae. A vast genus--probably the most extensive in the vegetable kingdom--comprising, according to Bentham and Hooker, nearly 900 species of stove, greenhouse, or hardy, annual, biennial, or perennial herbs, sub-shrubs, or shrubs, rarely arborescent, dispersed over the whole globe, but most numerous in temperate or mountainous regions. Flower-heads radiatheterogamous or discoid-homogamous, solitary or corymbose, very rarely disposed in pyramidal panicles, subracemose or sessile at the sides of the branches; involucral bracts in one series, with sometimes a few smaller ones at the base, at lenght often reflexed; receptacle flat or slightly, convex; ray florets, when present, variously coloured, one-seriate, ligulate; disk yellow, whitish, or rarely purplish or violet; achenes glabrous or slightly villous, of variable form and size. Leaves alternate or radical, entire, toothed, lobed, or variously (often pinnately) dissected. The genus is represented in Britain by nine species (two of which, however, are not indigenous, but have become naturalised), including the Ragweed or Ragwort (S. Jacoboea) and Groundsel (S. vulgaris). South Africa is richest in species in the Old World, and the Andean region in the New. A representative selection of the plants best known to horticulturists is given below. Senecios are easy to grow; they succeed in almost any loamy soil. The annuals may readily be increased by seeds, which, in many instances, ripen in abundance. Other representatives of the genus may be propagated by seeds, by divisions, or by cuttings both of the shoots and roots. See also Cacalia, Cineraria, and Ligularia.
