App. I. Half-hardy Genera belonging to the Order Compdsita. 



Though there are few plants belonging to the order Comp6sita?, 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, 

 and chiefly refer for the species to our Hortus Britannicus. 



Carlowizia. salicifdlia Mcench, Onobroma -salicifblia Link, is a native of Madeira, growing to the 

 height of 2ft It is an erect shrub, with hoary leaves, resembling those of a willow. 



Arctotis 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. Keg., t 34.) has yellow rays, and grows to the height of 3 ft., -flowering from June 

 to September.

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

 ering in June and July. 



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

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

 B. zrandiftdra W. (Bot. Mag., t 1844.) is often in collections. 



Cullum\& R. 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. 



Oth6nna is a Cape genus, of which there are numerous low undershrubs, 

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

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

 timita Bot. Mag., t. 306. ; and O. coronopifolia ; are species frequent in col- 

 lections. 



Ostcospdrmum 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 Encyclopaedia of Plants ; and 0. pisifcrum 

 L. (Bot. Cab., t.470. ; and our 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 2ft. or 3ft., producing yellow flowers from 

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

 Reg., t. 40. ; and our fig. 851.), may serve to exemplify the genus. 



Mutisia 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 

 yet been introduced. M. latifolia D. Don in 

 Brit. Fl.-Gard.,2d ser.,t. 288., and our jtfg. 852., 

 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 

 cordate-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 Sin. 

 long. M. arachn'oidea Mart. (Bot. Mag., t. 

 2705.) 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 

 the slightest protection, and appears perfectly 

 hardy. Mutism latifolia represents a family of 

 climbers so very different from every other hitherto propagated in British
