F O R this we are also indebted to Mr. Dickson, who gathered
it about the roots of trees in some Scottish woods. Dr. Scott
is said to have collected the same in Ireland. We cannot adopt
the synonym of Scopoli’s rotund folium, though there is a considerable
likeness in his figure to ours; but his lid is pointed,
ours flat.
The stems are slender, creeping and scaly, throwing up
numerous, simple or divided, short, nearly lanceolate branches.
Leaves imbricated in two rows, bright green, ovate, acute,
finely serrated, with a fine central rib, scarcely visible to the
end. Fruitstalk short, tawny. Sheath-leaves with a twisted
serrated point, but no rib. Capsule ovate, inclining, more or
less curved. Fringe brown. The lid is wanting in our present
specimen; but we have found it, in another authentic one in
Mr. Turner’s possession, nearly flat, with a small central prominence.
