This curious plant, though having so much the habit~ and 
the spherical capsule of a Bartramia, has nevertheless a simple 
peristome. Uuacquainted however with the calyptra, I place 
it with some degree of doubt amongst the Weissie. In the form 
of the capsule it approaches W. Martiana (Tas. CIV. of this 
work) and W,. nigrita, from both of which in other respects it is 
widely different.
