ERICE^ NORMALES.

 bucciniflora. 



Professor Don, which appears very distinct, 

 though it also has not been generally adopted. 

 It includes all those beautiful Cape Heaths 

 which have a shining, glutinous, ventricose, or 

 cylindrical corolla with a _ 

 spreading limb (see« in^^. 50), 

 and a capitate stigma (b). C. 

 bucciniflora and C. ventricosa, 

 are examples of this genus. 



The Ling or Heather, which 

 Linnaeus called Erica vulgaris^ 

 is now generally placed by all 

 botanists in a separate genus 

 called Calluna, which was es- 

 tablished by Mr. Salisbury. The calyx of this 

 plant is membranous, and coloured so as to 

 resemble a corolla, and it is furnished 

 with four bracts at the base, which 

 resemble a calyx. The true corolla 

 is bell-shaped, and shorter than the 

 calyx. The stamens are inclosed, 

 and the anthers are of the very 

 singular form shown in Jig. 51. 

 The stigma is capitate, and the flowers are 

 disposed in what is called a racemose spike. 

 The leaves are trigonal ; they are very short, 

 and they are laid over each other like scales 

 in four rows. The Ling is the only species in the 

 genus.
