802 HISTORY OF BRITISH MOSSES, 



" "When the streams break forth from their wintry chains, 

 In the joyous months of Spring, 

 And the earth is glad with the gentle rains. 

 And the cuckoo comes to sing." 



There is a variety found in dry situations in the winter 

 months^ with the fronds dichotomously divided at the apex.
