TRIANDRIA— MONOGYNIA. Scirpus. 55 



Found by Mr. Haworth in a low marshy meadow, half a mile from 

 Little Chelsea. Hooker. 



Annual. September. 



Root of many simple fibres. Stems several, about 6 inches high, 

 smooth and pliant. Spikes numerous. GL brown, more or less 

 dark, pale at the keel ; the lower ones gradually deciduous with 

 the seed. Stam. but 2 according to Dr. Hooker ; 3 are repre- 

 sented in Fl. Dan. as well as by Leers, Poiteau, and Bauer. 

 We have seen no living specimens to settle this matter. The 

 seed is triangular, inequilateral, pale, with a simple beak. Will- 

 denow, Vahl, and even Schrader, copy Linnseus's erroneous 

 reference to Morison, t. 9, for 11.
