Cornwall is a paradise for the botanist and geologist, because for the former there are rare species and some altogether unknown elsewhere, such as the erica vagans so often mentioned, which grows in the neighbourhood of the Lizard.
"Cornwall"
G. E. Mitton
The meek green fields carry one down almost to the shore, for though we have come across a bit of heath en route which recalls how repeatedly we have been told that the erica vagans grows here and nowhere else, we leave this behind and wind once more between grass fields toward the dreary little cluster of houses called Lizard-town, which looks not unlike a forsaken coast-guard station from the distance.

On the summits of the Maures, and on all the mountains bordering the Riviera, grows the heath erica arborea, from whose roots pipes are made.
