side, distinguish this plant from V. leptophylla: yet so closely
is it allied to that species, that the propriety of separating
it may admit of doubt. We can by no means regard it,
with Wahlenberg, as a variety of V. miniata, nor refer, as
he does, to t. 2012. ƒ. 1. of this work as a representation of
it. We are, indeed, now aware of a different error in that
plate; the Loch Lomond specimens only, jig. 2, being
V. leptophylla, and those from the Hill of Kinnoul, jig. 1,
a mere state of V. squamulosa, (the Endocarpon squamulo-
sum of Acharius, Lich. Univ. p. 299.) of which our L. lach-
neus, t. 1698, is but another variety. V. leptophylla, like
V. euploca, is affixed by a central callus, and destitute of
fibres on the underside.
Mr. Robertson has discovered an English station of the
true V. leptoplwlla,—rocks by Bassenthwaithe Water, Cumberland.—
