546 ARBORETUM ET FRUTICETUM BRITANNICUM. 
Sene‘cto Lessing. Receptacle naked, or alveolate. Styles penciled. Pap- 
pus pilose, caducous. 
Muti’sza Cav. Receptacle naked. Achenia somewhat beaked. Pappus of 
many series, feathery. 
With the exception of Baccharis, there is scarcely a plant belonging to 
the order Compésite 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 off. Nevertheless, in a 
technical enumeration of trees and shrubs, these species could not be omitted.
