Brook: Phcenological Observations on Mosses. 135 



considers a moss to have ripe fruit when five to ten lids are detached 

 from a specimen in situ. The lids are detached from dried specimens 

 often before ripe. The following is a list of the species to be observed, 

 and the various dates, so far as Mr. Arnell has observed them, for 

 Hernoesand, Sweden : —

The time occupied in maturing the fruit varies very much in different
