Watson further brought out the striking fact that the west and east of Britain each had species peculiar to it; the former he characterized as Atlantic, the latter as Germanic. The Cornish heath (Erica vagans) and the maiden-hair fern (Adiantum CapillusVeneris) may serve as instances of the one, the man-orchis (Aceras anthropophora) and Reseda lutea of the other.
On its western shores there are some twenty, such as Saxifraga umbrosa, Erica mediterranea and Arbutus unedo, which are not found in Britain at all.
Hemsley remarks that the northerr genus Erica, which covers thousands of square miles in Europe with very few species, is represented by hundreds of species in I comparatively small area in South Africa.
Soc., 1869, p. 25) points out that the west European species of Erica, Genisteae, Lobelia, Gladiolus, &c., an some of them more nearly allied to corresponding Cape species thai they are to each other; and many of the somewhat higher races of ~, mrnl ~prmprs, h,i-mr~ pvdprii-1v div~rmred from stock now unrepresented anywhere but in South Africa.

Heath (Erica tetralix) and ling (Calluna vulgaris) cover all the waste sandy regions in the eastern division of the country.
The total absence of a few of the more common forms of northern Europe and Asia should also be noticed, among which may be named Tilia, Fagus, Arbutus, Erica, Azalea and Cistacae.
