ioo THE GENERA AND THEIR SPECIES. 



72. F. myurus. Waste places, rocks, tops of walls and 

 other dry situations ; ranging through Central and Southern 

 Europe. June and July. Root annual, tufted, fibrous. Stems 

 numerous, erect, slender, smooth ; nodes three, smooth. Leaves 

 of a richer dark green than any other grass, narrow, involute, 

 ribs acute and hairy. Sheaths loose, smooth, striated, uppermost 

 reaching panicle ; ligule auricled, short and abrupt. Panicle 

 three inches long, slender, feathery, curving or erect ; rachis 

 rough, branches short, rough, and angular. Spikelets with five 

 florets, narrow, upright, unilateral, longer than glumes. Glumes 

 very unequal, smooth, keeled, larger three-ribbed and three times 

 the size of the smaller, which has only one rib. Outer palea 

 lanceolate, pointed, as long as the larger glume, with a rough, 

 slender awn as long as itself ; inner palea thin, lanceolate, toothed 

 at apex. 



Varieties — 



F. bromoides. Panicle long and slender. 



F. ambigua. Panicle close and feathery. 



F. sciuroides. Upper sheath not reaching panicle. 



73. F. uniglumis. Sandy shores, ranging from the Mediter- 

 ranean through Western Europe, not found in Scotland. June 

 and July. Root annual, fibrous. Stems several, spreading, 

 geniculate at base, leafy. Leaves linear, narrow, convolute, 

 rigid, hairy above, smooth below. Sheaths loose, smooth, 

 striated, uppermost not reaching panicle ; ligule auricled, short, 

 membranous, torn. Panicle unilateral, short, close. Spikelets 

 with four or more florets, crowded, pedicels erect, short, and 

 thickened at apex. Glumes very unequal, the outer the larger, 

 keeled, long awned ; inner glume absent or sufficiently minute to 

 justify the specific name. Outer palea short, three-ribbed, awn 

 longer than palea ; inner palea shorter than outer, trifid at 

 apex, with two green lateral ribs. In Britain this is a littoral 

 species, but on the Continent it is not confined to the shore.
