290 The Flora of Wiltshire. 



Glumes small, obtuse. A coarse grass, making the great part of the 

 hay in marshy lands. 



2. G-. fluitans, (R. Br.) floating Sweet-grass. Engl. Bot. Suppl. 

 t. 2975. Porn. Gr. t. 95. 



Locality. By the sides of the Avon, canal, wet places and ditches. 

 P. Fl. June, September. Area, 1, 2, 3, 4, 5. Generally distributed 

 in all the Districts. Floivering stems decumbent and rooting at the 

 base. Sheaths smooth, striate. Leaves long, linear, acuminate, 

 pale green, rough on both surfaces. Ligule oblong. Panicle erect, 

 slender, very long, nearly simple. Spikelets linear, of 7 to 12 ad- 

 pressed lanceolate-oblong, acute flowers. Loioer palea nearly thrice 

 as long as broad. Anthers about five times as long as broad, purple., 

 pale yellow when empty. 1 



3. Gr. plicata, (Fries.) folded-leaved Meadow-grass. Reich Icones, 

 mi. 79. G. fluitans, (Sm.) Engl Bot. t. 1520. Parn. Gr. t. 45. 



Locality. Stagnant water and wet places. P. Fl. June, August. 

 Area, 1, 2, 3, 4, 5. In all the Districts but local, and not so frequent 

 as the last species, G. fluitans, but doubtless often passed over for it. 

 Panicle rather broad and compound, nearly smooth, erect with 

 flowers, divaricate with fruit. Spikelets oblong, linear, of 4 to 12 

 oval-oblong, rather acute flowers. Lower pale twice as long as broad* 

 Sheaths rough, furrowed. Leaves glaucous, bluntish, plicate when 

 young. Ligule shorter. Anthers about three times as broad as long, 

 cream-coloured, fuscous when empty. This species cannot well be 

 mistaken for G. fluitans, on account of the compound panicle, with 

 much more numerous spikelets.

1 The abundance of this grass about the ditches of Cheddar is said to be the 

 cause of Cheddar cheese being so famous. T t B.F.
