P r e c e d in g authors have mentioned this as a rare mountain
plant. Dillenius was not aware of having seen it. Mr,
Hooker however assures us that it is common in various parts of
the kingdom, either on a boggy or a loamy soil. Our specimens
in fruit were sent by Mr. Lyell to Mr, Hooker, but not in time
to appear in his admirable work. He has therefore obligingly
communicated them to us. The stems creep frequently on the
ground, or over neighbouring mosses, and are generally branched,
from half an inch to an inch long, clothed with two rows of
crowded, spreading, squarish leaves, whose extremity is cloven
into two sharp distant points, by a wide rounded notch, in which
last character, its greater size, and more branched habit, this
species differs from excisa, t. 2497, as well as in the great abundance
of granulations, now known to be buds, at the tips of the
leaves. In consequence of this ample mode of increase, it
seems the capsules are rarely perfected, though the plaited,
toothed, gradually elongated sheaths often occur, falling off prematurely.
