Bell Heather or Fine-leaved Heath {Erica 

 dnerea) has leaves three in a whorl. It grows on 

 dry places and similar situations to common 

 heather. The flower-bells are purple. The taste 

 of the leaves is more bitter than that of common 

 heather. It flowers in July and August, appearing 

 before the common heather. 



Cross-leaved Heath {Erica tetralij:) has leaves 

 four in a whorl and placed crosswise. It has rose- 

 coloured flowers, and grows in similar situations 

 to common heather. Flowers in July and August. 

 Grouse do not seem to care much for the two 

 last-named heaths.
