In one Individual out of a great number of specimens which I
have examined, I found the calyptra cleft on one side about a
fourth of the length upward. This I suppose to be an accidental
circumstance, as we know it sometimes to happen in the genus
Grimmia and Trichostomum ; and, taking it for granted
that the veil is in reality mitriform, I place this plant among the
Hookerioe, though I regret to say it does not accord in liabit witli
any other species of the genus. The general appearance of the
plant is that of a Neckera; and its capsule is, as in that tribe
and in most Leskeæ, erect. Those who have most studied the
mosses will be best aware how difficult it is to form generic characters
from the parts of fructification, which shall include only
those individuals which appear allied by nature.
