Of the forms quoted above, f. typica and f. turgida are 

 the most common, but f. vadorum and f. angustifrons are also 

 pretty common at some places. The plant often bears, in 

 the upper and barren segments, long and rathernarrow air- 

 bladders like those by the preceding species, and on the same 

 individaal air-bladders of the common forra besides. It is 

 litoral, growing in the upper as well as in the lower part 

 of the zone, and sometimes descending a little below low- 

 water mark. It bears receptacles in June, July and August. 



DistribuUon: Common and yqtj abundant everywhere.
