Genus I. 
Rem 
ERICA D. Don. Tue Heata. Lin. Syst. Octandria Monogynia. 
Identification. D. Don in Edinb. New Phil. Journ., 17. p, 152.; Don’s Mill., 3. p. 790. 
Synonyme. Erica sp. of Linnzus and other authors. 
Derivation. The erica of Pliny is altered from the ereiké of Theophrastus, which is derived from 
ereikO, to break; from the supposed quality of some of the species, of breaking the stone in the 
bladder, 
Description. Evergreen shrubs, with needle-like leaves, and hair-like 
roots; natives of Europe and Africa; varying in height from 6 in, to 2 ft. or 
3 ft.; a number of them growing as high as 6 ft., and some few of them, as 
E. australis and £. arborea, attaining the height of 12ft. or 15ft. In 
British gardens, they are propagated by cuttings taken from the points of the 
growing shoots, and planted in pure sand, and covered with a hand-glass or a 
bell-glass. Many of the species of this genus are propagated more readily by 
seeds, than by layers or by division of the plant. They are all, without ex- 
ception, eminently beautiful; and almost all are absolute in their choice of 
soil, which is that of sandy peat or heath mould ; and of the situation in which 
they will grow, which should be elevated and airy, yet not arid. The price 
of plants, in British nurseries, varies from 6d. to 2s. 6d. each; at Bollwyller, 
the only hardy species is Z. cinérea, which is 1 franc and 50 cents; and none 
appear to be cultivated as hardy in the nurseries of New York.
