strong fibres. Stems rather bulbous at the base, with a single 

 joint near the bottom. Leaves taper-pointed, rough, except at 

 the back j besprinkled with hairs on the upper surface, particu- 

 larly towards the top of the sheath. Panicle oblong, of numerous, 

 compound, close, furrowed, wavy, scarcely rough, branches. Fl. 

 dull violet-coloured, or brown, smooth. Cat. lanceolate, acute, 

 single-ribbed, compressed, unequal. Outer valve of the cor. of 

 a similar figure ; inner abrupt. Anth. violet-coloured. Stalk of 

 the spikelet much elongated, with 1 perfect jioret, sessile at its 

 base ; another on a level with the shorter valve of the cal., and 

 1 or 2 neuter ones higher up. Seed loose, polished, invested 

 with the hardened cor., in which this grass differs from Aira, 

 whose petals remain membranous. 

 Shady situations render the 'panicle pale, brownish, or whitish. The 

 stems are said to be used for brooms, or even baskets, where 

 better materials are rare.
