In a pool at Cnllercoats. — August, 1856. — E. Foster. The 



specimen here alluded to is the only one which I have seen from 



our district. It is an interesting addition to our list, only a very 



few English localities having been hitherto recorded, and those 



all on the south coast. It is of frequent occurrence on the west 



of Scotland and Ireland ; but except in this instance, appears 



not to have been noticed on the east coast of Britain. — N.

 On rocks between tide marks. Common. An extremely 

 variable species in size and general appearance, the most luxu- 

 riant specimens being found near low-water mark. I can find 

 no notice in any edition of Dr. Johnston's " Flora" of the L. 

 ohtusa, w^hich Mr. Winch gives on his authority. It is possible 

 that Dr. Johnston may once have called some variety of the 

 present plant by that name. — N. D.
