Ericaceæ (Calluna vulgaris) Heather.
(Erica cinerea) Grey Heath.

Grey Heath.

The Heaths are, for the most part, social plants, growing in great numbers on waste ground, and giving great beauty to scenery. The Heather gives a peculiar aspect to the hills of Scotland. Humboldt observes, "It is curious that, out of more than 300 species of Erica, one only should be found throughout the whole American continent."
