It is with much pleasure that I acknowledge the kindness of
Professor Swartz, who has enabled me to publish this species
which in so many particulars agrees with the Jungermannia
eriocaula. (T a b . LXXII.) In addition to the differences between
them there noticed, I may add that J . fucoides has the
fronds (pinnse of Swartz) more distantly placed, their divisions
far less numerous, move patent, broader, more decidedly reticulated,
of a browner colour inclining to reddish, of a thinner texture,
and having a nerve much narrower in proportion to the diameter
of the segments.
