Synonyme. Erica sp. of Linnaeus and other authors. 



Derivation. The erica of Pliny is altered from the ereikgof Theophrastus, which is derived from 



crci&o, to break j 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 E. 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 E. cinerea, which is 1 franc and 50 cents ; and none 

 appear to be cultivated as hardy in the nurseries of New York.
