THE ANKER VALLEY AND ITS FLORA. 
.4, Highland type.—Species chiefly seen about mountains. 
5. Germanic type.—Species chiefly se,en in East Britain. 
6. Atlantic type.—Species chieffy seen in West Britain. 
Of these only four of the types are represented in the 
district, and as it will better illustrate the nature of the 
Anker flora, I shall give both the flora of that valley and 
that of the 120 Sence Valley plants separately. They will be 
as follows :—

The remaining 100 are either varieties, aliens, or casuals not 
classified by Watson. 
It may be interesting to compare the flora of the Anker 
with that of another Warwickshire River, the Blythe, and with 
that of Britain as a whole. 
The Blythe, which rises near Earlswood, on the Worces¬ 
tershire side of the county, is for a considerable part of its 
course an insignificant stream, and its course from its source 
to its confluence with the Tame, near Hams Hall, is about 
twenty-three miles. The district drained by it is strictly 
agricultural. The woods are usually small but fairly abun¬ 
dant, and the district as a whole is flat, but having many 
minor streams is well watered. The prevailing rocks are 
those of the New Red Sandstone. In this district I find 825 
flowering plants and ferns, or about 142 more than in the 
Warwickshire portion of the Anker basin, and twenty-three 
more than in that of the Anker basin as a whole. 
The following table will show the distribution of native 
plants throughout Great Britain, and the relative distribution 
in the valleys of the Anker and Blythe :—

So that it will be seen that whilst the Blythe basin yields 
one half the British native flora, that of the Anker only yields 
a little more than one-third the British flora; and I find that
