SEA CLUB RUSH 209 



The stamens with 2 half-anthers and the carpels with 2 stigmas 

 are borne in two rows on a spadix enclosed in a spathe. The flowers 

 are submerged. The pollen tubes are long thread-like bodies, which 

 float in sea water at any depth, having the same specific gravity. The 

 hairlike stigmas being large and projecting easily catch some of the 

 threads, and are pollinated in this way by water as trees are by the 

 wind. 



The fruit is an achene, which is furrowed, and the plant being 

 immersed the seeds are dispersed by water. 



This species is aquatic and confined to sea water. 



A beetle, H<zuionia Curtisi, is found on it. 



Zostera. Linnaeus, is from the Greek zoster, o-irdle, in allusion to 



o 



the long strap-shaped, streaming leaves. The meaning of the specific 

 name is obvious. 



Grass Wrack is also called Barnacle-grass, Drew, Sweet Grass, 

 Grass-weed, Mallow, Sleech, Widgeon Grass, and Sea Wrack. 

 Another name is Bellware, this plant being the " Seaweed " from 

 which kelp is made. 



The leaves are used as manure in Sweden and Holland, and used 

 for stuffing packing-cases, beds, and cushions, being flexible. It is 

 used for the covering of liqueur flasks. It is also employed for thatch- 

 ing, roofs thus made lasting over 100 years. Grass Wrack is also used 

 for packing glass and china.
