Leaves longer and broader than in M. hrackydontia, all circularly arcuato- 

 incurved when dry, and glossy at the back. The fruit has only been found 

 at Angoul6me, in France, by M. Philibert in 1867, for some of whose speci- 

 mens I am indebted to the kindness of M. Husnot. Some botanists have 

 been disposed to refer this moss to Mollia tortuosa, but they are quite distinct, 

 and the glossy stiff little cushions of M. nitida have an aspect so peculiar that 

 it may always be identified by the naked eye alone.
