56 TRIANDRIA— MONOGYNIA. Scirpus. 



Near Yarmouth, Norfolk. Mr. D. Turner. 



Perennial. August. 



Smaller than the last, with several barren stems, but no real leaves. 

 The numerous radical polished imbricated scales are also want- 

 ing, there being only a very few thin and narrow ones, besides 

 the close abrupt sheaths which embrace each stem. Spike smaller 

 and blacker than in S. ccespitosus, but, except when starved, 

 twice as long as the 2 outer glumes, which end in a rounded 

 membranous border. Seed grey, shining, obtuse, with a brown 

 point, and at the base 6 fine rough bristles. 



I prefer Lightfoot's unexceptionable and original name to the 

 pedantic one of Ehrhart, foisted, like many other such, by him, 

 into the Supplementum of Linnaeus, while printing ; contrary to 

 the author's intention.

Stem branched, leafy, pliant and floating. Flower-stalks
