Mr. Wilson remarks that this moss, which is usually found near the seacoast in Britain, 
is rare in fruit; and the often imperfect peristome renders it difficult to distinguish from 
Gymnostomum tortile. Mitten says of Mr. Travers’s specimens, that the leaves are only 
half as wide as in the European specimens, gradually tapering, and the operadum in a young 
state exceeds the capsule ; it may be a different species.
