N o t uncommon among tufts of moss in shady woods. The
fructification is said to be produced in February and March, but
neither Mr. Hooker nor ourselves have yet obtained it. Dille-
nius represents the sheaths and capsules, in sufficient abundance,
all situated on the upper side of the branches, especially towards
the bottom.
The shoots are branched and straggling, sticking by their minute
radicles to the neighbouring mosses, beset with two close
ranks of flat, vertical, entire, opposite, pale and pellucid leaves,
which vary in shape and acuteness, and are very tender, shrivelling
up as soon as they begin to dry. Between each pair, underneath,
is a minute, roundish, sharply-notched scale, accompanied
by a little tuft of radicles. The definition in Linnæus, “ leaflets
awlshaped,” is founded in some error, and he has erased it in his
own copy of Sp. PI.
