and plants have stood against the wall in the Horticultural Society's Garden for 6 years, and been 

 found perfectly hardy. 



Culcitium salicinum Spr, t'acalia salicina Lab., (Bot. Hep., t. 923. ; and our fig. 862.) is a New 

 Holland* shrub, with succulent leares ; evergreen ; growing to the height of 6 ft ; and producing its 

 yellow flowers in June and July.

Caca^lia L. is a genus of which there are several sufTruticose species, with succulent leaves, varying 

 in height from 1 ft. to 6 ft., all of which might be tried on conservative rockwork. 



Franzerin arfcwwioldes W., and F. ambrosib'ldes Cav. Icon., 2. t. 200., are natives of Peru and Mexico, 

 growing to the height of from 4 ft. to 6ft., and producing their greenish flowers from July to Sep- 

 tember. 



(E'dern prolifera Thunb. (Bot. Mag., t. 1637.) is an evergreen undershrub, a native of the Cape, 

 growing to the height of 3ft., and producing its yellow flowers in May and June. 



859 





I'yri-thrum Sm. is a genus of which several species, natives of the 

 Camadas and TenerifFe, are suffiruticose, grow to the height of 3 ft., and 

 produce their white flowers all the year. P. fccniculaceum W. En. (Bot. 

 Reg., t 272. ; and our fig. 863.) will give an idea of the species. In a late 

 number of Sweet's Brit. Fl. Card., under the head of IsmC-lia maderense, 

 it is remarked, that all the shrubby Teneriffe and Canary plants, hitherto 

 considered as included in the genus .Pyrethrum, will, probably, be found 

 to belong to that of Ismclia. 



Athamisia L. is a genus of evergreen undershrubs, natives of the Cape, 

 of whicli A. pubtscens L. (Com. Hort., 2. 47. ; Encyc. of Plants, p. 696. 

 f. 11662.) is deserving of a place against a conservative wall. This plant 

 grows to the height of 6 ft., and produces its yellow flowers from June to 

 August. 



Balsamlta zgcratifolia Desf. (Alp. Ex., t. 326.) i;.a native of Candia, 



f rowing to the height of 2ft., and producing its yellow flowers from 

 une to October. It deserves a place against a conservative wall or 

 rock. 



r\<!ntzzflabellif6rmis W., Tanacetum flabelliMrme L'HMt., (Bot. Mag-. 

 t 212.) is an evergreen undershrub, a native of the Cape, which grows to the height of 4ft., and 

 produces its yellow flowers from May to August. It is interesting for its silvery fan-shaped leaves. 



Erioce"phalus africanus L. (Bot. Mag., t. 893.) is an evergreen Cape shrub, which grows to the 

 height of 8 ft. and though not remarkable in its flowers, which are yellow, has yet very interesting 

 leaves, which have a whitish hue, and are divided into narrow filaments, so as to somewhat resemble 

 those of the southernwood ; they are also odorous when slightly rubbed. 



Senecio L. is a genus of which there are several Cape and South American sj>ecies that are 

 suft'ruticose and evergreen ; and which, if planted in dry soil, against a wall, or on rockwurk in a 

 very warm situation, might probably admit of being protected during winter. In the wannest parts 

 of Cornwall and Devonshire, some of the species are treated as border flowers, and found to be 

 hardier than pelargoniums. S. elegans plena rubra Bot. Mag., t. 238., has been so treated. S. liKicimis 

 Link grows to the height of 6ft., and flowers in June and July. It would form a most ornamental 

 plant if trained to a wall. 



Tarchonanthus camphorntus Lam. 111., 671., is not rare in old botanical collections. It has whitish, 

 somewhat ovate, leaves, with an odour more or less camphor-like. Planted out under a wall for the 

 summer, it grows freely. 



Eridcomafragrans D Don is a native of Mexico, beautiful in its panicles of white-rayed heads 

 of fragrant flowers ; and it has large leaves. 



Various other genera of Compdsitte afford half-hardy suffruticose species ; but some ofthese areof 

 such humble growth, that they are better adapted for being considered as half-hardy herbaceous plants 

 than shrubs. Those, however, who wish to pursue the subject as far as it will go, may turn to the 

 following genera in our Hortus Britannicus and Gardener's Magazine : Ccntauria, Kentrophijllum 

 (K. arborfscens is 6 ft. high), Stobte^ (S. pinnata is 4 ft.high), Bacaziz, Cichnrium, Ro/dndi-a, N6cca, 

 /'/v/wrria, EmpotMstn, Mikania, \mellus, GrindtRa, Diplopdppus, Neja, Erigero*. Pteronia. 

 Whupthalmutn, Diomtdia, Zcxmenia, Montanba, Lidb^ckia, Achilles, Tanacetum, Hippla, Casslnia 

 (C. leptophyla is very shrubby), Ixbdia, Ozothdmnus, Leucostdmma, AphcUxis, Syncarpha, Mr~ 

 talatia, Sttfbc, Phcenocoma, Let/sera, Kcl/iania, Osrnltcs, Trixis.
