Half-hardy Genera belonging to the Order Comjwsitcc. 



Though there arc few plants belonging to the order Composita?, whether hardy or half-hardy, 

 which are truly ligneous, yet there are a number which are suffruticose ; and which, though usually 

 kept in the frame, green-house, or even stove, may be tried, with every prospect of success, at the base 

 of a conservative wall, or on rockwork which is capable of being protected during winter. We shall 

 notice the genera to which these belong in the order in which they are given in Lessing's Synopsis, 

 ami chiefly refer for the species to our llortus Britannicus. 



Cartovotoau salicif'dlia Sfoench, Onobrbma salicifblia Link, is a native of Madeira, growing to the 

 height of J ft. It is an erect shrub, with hoary leaves, resembling those of a willow. 



Arci'otis L. This is a very interesting family consisting of undershrubs, all natives of the Cape of 

 Good Hope, and very splendid when in flower. The colour of the rays is yellow, orange, purple, or 

 white. Several, or perhaps all, of them might partly be preserved at the base of a conservative wall. 



A. dspera L. {Bot. Beg., t. 34.) has yellow rays, and grows to the height of 3 ft., flowering from June 

 to September. 



Didt'lta carnbsum and D. spinbsum H. K. are Cape shrubs, growing to the height of 3 ft, and flow- 

 ering in June and Julv. 



Berckhiya Ehrh. is a Cape genus, of which there are 7 suffruticose species introduced, which 

 grow to trie height of 3 ft, and produce their yellow flowers from June to August 

 />'. grandiflbra W. [But. Mag., t 1844.) is often in collections. 



vitUiamz B. Br. is a Cape genus of evergreen undershrubs, of which 3 species 

 have been introduced,] which grow to the height of 2 ft., and produce their bright 

 yellow flowers from May to August. 



Cithonna is a Cape genus, of which there are numerous low undershrubs, 

 evergreen, some of them rising as high as 3 ft. O. ftabcllifblia Bot Cab., t. 

 728. 0. virginea L. and our fig. 847.; O. pinnuta Bot. Mag., t 768. ; O. pec- 

 tinata Bot. Mag., t 306. ; and O. coronopifblia ; are species frequent in col- 

 lections. 



Osteospdrjnum is a Cape genus of low evergreen shrubs, growing to the 

 height of 8 ft. or 10 ft, and producing their yellow flowers from April to August 

 Several of them are figured in our Encyclopedia of Plants ; and 0. pisiferum 

 L. {Bot. Cab., 1 470. ; and out figs. 848, 849, and 850.) will give a some idea of 

 the general appearance of the genus. 



Calendula is a genus of which several species are natives of the Cape, and 

 are evergreens, rising as high as 2 ft. or 3ft, producing yellow flowers from 

 April to August. All the species are beautiful. C. chrysanthcmifbliaVm. (Bot 

 Keg., t 40. ; and our fig. 851.), may serve to exemplify' the genus. 



Mutkh. Cav. This is an exceedingly interesting genus of shrubby climb- 

 ers, with leaves terminating in tendrils, by the 

 prehension of which the stems are supported. 

 The species are natives of South America, and 

 only three of them, as far as we know, have 

 j et been introduced. M. latifolia D. Don in 



lint. F/.-(;md.,vd ser., t. 288.,and our/g.852., IS^G^^f^, 



is a native of Valparaiso, which has flowered in 

 a frame at Kilmington Rectory, Wilts. The 

 flowers are pale pink and yellow, and the leaves 

 ( oi date-oblong, ending in a scollop, or notch, 

 the midrib of the leaf being extended up the 

 blade of the leaf, through the centre of the 

 notch, and being continued into a tendril 3 in. 

 long. M. arachnoidal Mart. {Bot. Mag., t. 

 £705.) is a native of Brazil, with red flowers, 

 produced in July and August. A plant, ap- 

 parently of the former species has stood out 

 three winters in the Clapton Nursery, without 

 lightest protection, and appears perfectly 

 hardy. Mutuia latifolia represents a family of 

 climbers so very different from every other hitherto propagated in British
