Caules cespitosi, repentes, subpinnatim ramosi, ramis non raro 
erectis, caulibus ramisque inferne ubique tomento ferrugineo 
obsitis stipulisque admixtis, Folia viridia, disticha, subhori- 
zontalia, ligulata, parum undulata apice insigniter involuta, 
Siccitate torta, nervo valido fusco pereursa. Perichetialia 
circa capsulam undique imbricata, lanceolata, stricta, fusca, 
nervo obscuro. Stipule parve, lanceolate, stricte, nervo di- 
stincto. Seta perbrevis. Capsula oblongo-ovata, pericheti- 
alibus obtecta. Operculum planum medio umbonatum. 
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 Anictangiuim, especially with 
A, ciliatum and imberbe, 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- 
mannia. 
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,
