142. Bryum uliginosum (Bruch) Bi. eur. 



N. Iceland: Husavik!; Svinadalur!. W. Iceland: Haukadalsheidi!, at 

 an altitude of about 300 metres. 



In all the above localilies it grew abundantly on dam]), sandy ground. 



On Haukadalsheidi the fruit was 

 ripe on Aug. Ist, in the other localities it 

 was unripe in the middle of Juh'. 



Besides J* and 5 flowers, a few 

 hermaphrodilc flowers also occur fre- 

 quentl^^ The papillæ of the peristome 

 fire in the lowermost transverse seg- 

 ments often distinctly arranged in 

 transverse rows, and sometimes there 

 are also distinct transverse bars as in 

 B. jjiirpnrascens. As is the case in 

 the latter species, the ripe capsule 

 contains a colouring matter which on 

 being treated with ammonia assumes 

 a red colour in the air.
