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

 found perfectly hardy. 



Culcitiiim saiicinum Spr., Cacilia salicina Lab., {Boi. Rep., t. 923. ; and our fig. 862.) is a New 

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

 yellow flowers in June and July. 



85S 



Caca'lia \j. is a genus of which there are several sufTruticose species, with succulent leaves, varying 

 in height from 1 ft. to f> ft., all of which might Ix? tried on conservative rockwork. 



frnmrria ar/c?WMioidcs U'.,and F. ambrosiiihlcs Cav . Icon., 2. t. 200., are natives of Peru and Mexico, 

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

 tember. 



(E'derz prnlifera Thunb. [Bot. Mng.,t. 1637.) is an evergreen undershrub, a native of the Cape, 

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



859 



Vyritknrm Sm. is a genus of which several species, natives of the 

 Canailas and Tencriffe, are suff'ruticose, grow to the height of ;J ft., and 

 protluce their white flowers all the year. P. (ccniculaccuin W. En. {Bot. 

 Reg., t. 272. ; and oar fig. 86.'3.) will give an idea of the species. In a late 

 number of Sweet's Brit. Fl. Gard., under the head of Ismc/ia maderi?nse, 

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

 considered as included in the genus /'yrethrum, will, probably, be found 

 to belong to that of Ismilia. 



Athaniisia Ij. is a genus of evergreen undershrubs, natives of the Cape, 

 of which A. puMscens L. {Com. Hort., 2.47.; Encyc.of Plants, p. 6!)6. 

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

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

 August 



Balsamlta agcratifWui Dcsf. {Alp. Ex., t. 326.) is a native of Candia, 

 growing to the height of 2 ft , and producing its yellow flowers from 

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

 rock. 



P\entzaflahellif6rmis W., Tanacfetum flabellifc'irme L'Heiit., (Bot. Mag. 

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

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



Eriociphalus africunus L. {Bot. Mag., t 89.3.) 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 verv 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 



Senicio L. is a genus of which there are several Cape and South American species that are 

 sufTruticose and evergreen ; and which, if planted in dry soil, against a wall, or on rockwork m a 

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

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

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

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

 plant if trained to a wall. 



Tarchonant/ius caryiphoratus Lam. 111., 671., is not rare in old botanical collections. It has whiti.sh, 

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

 summer, it grows freely. 



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

 of fragrant flowers ; and it has large leaves. 



I'arious other genera of Compdsitce aflford half-hardy sufTruticose species ; but some of (hcse areof 

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

 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 Britannicns and Gardoier's Magaxine : — Cenlauria, Kentrop/ij/lliim
