C hal on, J. — Note sur une forme tres reduite du Fucus limitaneus Mont. (Note 

 on a very reduced form of F. limitaneus.) 



[The author has found this plant on the rocks of Andagorria, opposite 

 Cape Figuier, where it covers the surface for some distance. The rocks 

 are calcareous, in horizontal layers, and are washed by the tides twice a 

 day. He finds great uniformity in the size and aspect of the plant 

 throughout the area, and is inclined to regard it as a species. The length 

 is constant : 10-15 mm. The author further points out striking specific 

 resemblance between F. platycarpus and F. vesiculosus.'}
