PLOUGHMAN'S SPINENARD: A genus of the polygama superflua order, belonging to the syngenesia clais of plants; and in the natural method ranking under the 49th order, Compositae discoider. The characters are: It has a naked receptacle, and hairy pappus; with a cylindrical imbricated calyx, and feminine florets mixed with the hermaphrodite ones. There are seven species, all natives of warm climates; but none of them merit notice except the two following. 1. The halimifolia, or African tree-groundsel, is a native of the Cape of Good Hope, as also of Peru and other warm parts of America. It grows to the height of five or six feet; and though there is little beauty in the flower, has been long admitted into the gardens of the curious. It is pretty hardy, and will live abroad in moderate winters in England, but is usually kept in green-houses and placed abroad only in summer. It may be propagated either by cuttings or by seeds, which ripen well in this country. 2. The halimifolia, or Virginia groundsel-tree, is a native of Virginia and other parts of North America. It grows about seven or eight feet high, with a crooked shrubby stem; and flowers in October: the flowers are white, and not very beautiful; but the leaves continuing green, has occasioned this shrub to be admitted into many curious gardens. It may be propagated by cuttings; and will live very well in the open air, though severe frosts will sometimes destroy it.
