Receptacle naked. Achenia somewhat beaked. Pappus of many series, feathery. With the exception of 5accharis, there is scarcely a plant belonging to the order Compdsitae which is truly ligneous, and at the same time hardy in British gardens, and sufficiently bulky for a general arboretum. Where an arboretum is planted on a lawn, and where it is not intended to cultivate the soil about the roots of the plants, there is not a single genus in this order, with the exception of that mentioned, which could with propriety be introduced. Even the common southernwood, if not planted in dug soil or on rockwork, would soon become stunted, and would ultimately die oif. Nevertheless, in a technical enumeration of trees and shrubs, these species could not be omitted. Genus I. STjEHELPN^ Lessing. The Stjehelina. Lin. Syst. Syngenesia Squalls. Identification.
