while in others they are five or six. The 

 general features of all the Heaths are, 

 however, the same — viz., there are eight sta- 

 mens, which are generally inclosed in the 

 corolla, though they sometimes project beyond 

 it, as shown in jig, 49, and the anthers of 

 which are two-cleft, and awned or crested 

 at the base, while the filaments are hair-like ; 

 one style, which always projects beyond the 

 corolla, and has a flattened stigma; a four-parted 

 calyx and corolla which is tubular, with a 

 four-parted limb. There are nearly two hundred 

 species of this genus, some of which are natives 

 of Europe, and others of the Cape of Good Hope. 



The moor Heaths {Gypsocallis) were separated 

 from the genus Erica, by Mr. Salisbury, princi- 

 pally on account of the corolla being campanu- 

 late, or shortly tubular, with a dilated mouth ; 

 and the stamens projecting beyond the corolla. 

 The filaments are also generally flat; the 

 anthers are without awns, and distinctly in two 

 parts ; and the stigma is simple, and scarcely 

 to be distinguished from the style. The com- 

 mon Cornish Heath {G. vagans), and the 

 Mediterranean Heath (G. Mediterranea) ^ are 

 examples of this genus, which appears strongly 

 marked, though, as 1 before mentioned, some 

 botanists do not adopt it. 



Callista is a genus established by the late
