This most remarkable moss, of which I have not had the good 
fortune to see the calyptra, accords so well in the other parts of 
its fructification with the genus Aniclangium, especially with 
A. ciliatum and imberle, that I have little hesitation in placing 
it with and near those species. The rest of the plant is never- 
theless totally different from them ; and were it not for the strong 
nerve in the leaves, might be readily mistaken for some Junger- 
mannit. 
Throughout their whole length the stems are covered beneath 
with a thick ferruginous down, intermixed with stipules, and the 
leaves, which grow in a distichous form, are, when dry, so much 
curled as to cover the whole upper surface of the stem, and if 
macerated for ever so great a length of time continue involuted 
in a most remarkable manner.
