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, (Tan. LXXII.) In addition to the differences be- 
tween them there noticed, I may add that .J. fucoides has the 
fronds (pinne of Swartz) more distantly placed, their divisions 
far less numerous, more patent, broader, more decidedly reticu- 
lated, of a browner colour inclining to reddish, of a thinner tex~ 
ture, and having a nerve much narrower in proportion to the dia- 
meter of the segments,
