By most of the older authors this moss appears to have been confused with 

 .^. cupressiformis Var. filiformis, so that it is not possible to separate them by the 

 descriptions ; the leaf-cells in the latter, however, are much longer and narrower 

 than in S. polyanthos, which, moreover, is generally found with fruit.
