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

 found perfectly hardy. 



Culcitiuni aaHcmttm Spr., Cacalia salicina Lab., {Bot. Hep., t. 923. ; and our Jig. 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.

Caccflia L. is a genus of which there are several suffruticose species, with succulent leaves, varying 

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



Franztria ai-temisioides 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 6 ft, and producing their greenish flowers from July to Sep- 

 tember. 



(E'dera. prolljera Thunb. {Bot. Mag., 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. 



Fyri-thrum Sm. is a genus of which several species, natives of the 

 Canadas and Teneriffe, are suffruticose, 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 Jig. 863.) will give an idea of the species. In a late 

 number of Sweet's Brit. Ft. Gard., under the head of Ismelia mader£nse, 

 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 Ismelia. 



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

 of which A. pube'scens L. {Com. Hort., 2. 47. ; Encyc. oj 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. 



Balsamlla ageratijhlia Desf. {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. 



py.ntxaJlabelliJ6rmis W., Tanacetum flabclliforme VIUriL, {Bot. Mag. 

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

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



Eriociphalus ajricunus 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 species that are 

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

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

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

 hardier than pelargoniums. S. elegant plena 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. 



Tarchonantlni \ eampherdtus Lam. 111., 671., is not rare in old botanical collections. It has whitish, 

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

 r, it grows freely. 



Eri6coma Jrhgrans I). Don is a native of Mexico, beautiful in its panicles of white-rayed heads 

 of fragrant flowers ; and it has large leaves.
