HAB. Among pebbles and under rocks. 



This moss is indeed worthy of its name, for few can compare with it for 

 its beautiful satiny lustre. Wilson's var. collinum appears to be a form with 

 subsecund leaves. I have added the two varieties from Limpricht's Laubmoose, 

 with the object of calling the attention of our collectors to them, as I have 

 not seen any British specimens. This variable moss has proved a source of 

 much confusion among botanists, as, following Spruce's lead, the European plant 

 was regarded as different from the American ; but by most recent bryologists they 

 are again united. The position of the capsule is of little moment, as it varies 

 with growth, and an erect one often becomes horizontal after the fall of the lid. 

 The nerves also vary in size and direction, and may be obsolete or reach to 

 the middle of the leaf, when it becomes Spruce's var. longinerve.
