Caules unciales, cæspitosi, inferne dense ferrugineo-tomentosi,
erecti, subramosi. Folia lutescente-viridia, undique laxe-disposita,
erecto-patentia, apice sæpe tortuosa, ovata vel ovato-
lanceolata, paululum carinata, margine argute serrata, nervo
ultra apicem in acumen longum producto instructa. Perichoe-
tialia paululum longiora. Seta unguicularls, terminalis, crocea.
Capsida crocea, pyriformis, vel, si mavis, ovata, apophysi
obconica capsula paululum longiore insideiis. Calyptra capsula
brevior, mitriformis, membranacea, pellucida, albida, basi ven-
tricosa, quadrifida, superne attenuata, superficies pilis longis,
flexuosis, articulatis, patentibus albis. Operciduni hemisphæricum,
apice in acumen angustum attenuatiim. Peristomium
e dentibus 8, lanceolatis, humectate iucurvis, siccitate erectis,
subcoriaceis luteis, transversim striatis, atque linea media longitudinali
obscure notatis.
Having fallen into an error in the Linnæan Transactions,
where I have described the teeth of this moss as 16 per paria approximatis,
whereas they are decidedly but 8 with a middle longitudinal
line, and having become possessed of noble specimens
with every part of the fructification in the most complete state, I
willingly publish another description and figure of it. The eight
teeth and the terminal fruitstalk constitute this plant an Octo-
llepkarurn. I am doubtful, however, whether 0 . alhidum has a
mitriform calyptra ; and if it have, I should propose that the present
subject be separated from it on that account, preserving to it
■•Bory de St. Vincent’s name of Orthodon. The ca yptra is a very
striking object, and rendered more so by the long hairs spreading
everyway. The whole plant inclines remarkably to yellow.
