 Raspberry family with large green leaves growing 

 among the heather on the mountain tops. It has 

 large white or rose-coloured flowers, which appear

 orange yellow. 



FIG. 2 



The CROWBERRY (Empetrum nigrum), Crakeberry, 

 Lingberry or Blackberried Heath, a small prostrate 

 plant with the habits of a heath. The purplish 

 flowers, which appear in May and June, are very 

 small, and are placed in the axils of the upper 

 leaves. The ripened berries are black.

 cinerea) 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. 



FIG. 4 



CROSS-LEAVED HEATH (Erica tetralix) 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.
