large forms of Hypnum illicebrum, Linn, which occur in the 

 southern portions of Europe ; but that species is at once distin- 

 guished by its somewhat smaller size, its shorter-rostrate opercu- 

 lum, and its strongly papillose pedicel. 



Hypnum purum is not unlike the moss under notice, but is 

 readily separated by (besides other and less striking characters) 

 its more pinnate ramification and shorter flexuose and more 

 slender branchlets.
