This plant in its bright and upright foliage is not much unlike
Neckera trichophylla of Swartz {Hypn,, Hedw.) ; but the peristome
is very remarkable : and were it not for the membrane
from which the peristome rises (exactly as in the inner fringe of
Neckera and Hypnum), it would very satisfactorily accord with
the genus Leucodon, where it may, at least for the present, be
allowed to remain. I can in no instance find a double peristome,
nor the least appearance of its having existed on any one of the
many capsules which I possess. But it must be observed that I
have not had the opportunity of examining a capsule upon which
the operculum was found.
