Brittany by Sabine Baring-Gould

The botany of Brittany is little varied owing to the slight variation in the soil and subsoil, schist and granite. It is but in rare spots where occurs limestone that the flora is different. It may be roughly divided into the class of plants that affect the inland districts and the moors, and that which flourishes on the seaboard. The flora of a slate and granitic region, whether in Scotland, Cornwall or Brittany, is much the same. In the Guérande, where there are extensive marshes, an interesting collection may be made of aquatic plants, both those living in sweet water bogs and those that grow in brackish water.

A complete flora cannot be here attempted; a brief account must suffice, with indications as to the habitat of the rarer specimens.
