 curved at the margin, and there ciliated. Flowers axillary, towards 

 the summit of the branches, rose colour, small. Berries black,

 according to Lightf., they yield a blackish brown dye.

This plant has a very agreeable smell ; the leaves a bitter taste. In 

 the Hebrides, according to Lightfoot, they are given as tea to de- 

 stroy worms : and occasionally they are used as hops in beer. In 

 Isla and Jura the inhabitants scent their clothes and their linen 

 with them. The catkins on being boiled are said to produce :i 

 scum like the wax of Myrlca cerifera and to be capable of being em- 

 ployed for the same domestic purposes.
