that it differs in various respects from the ordinary type of this species. The root is 

 generally rather much prolonged in a root-slocklike manner, the culms growing in tufts, 

 to 50 cm. high, thin and slender, relaxed, triangular, sUghtly rough towards the apex. 

 The leaves are narrow, only to 2 mm. broad, mostly of the same length as the culm, or 

 somewhat longer, slightly rough. The spike is generally formed from slightly separated 

 spikelets, ovate, or more commonly, longer, nearly cylindrical. The shape of each flower 

 agrees, for the rest, with the typical species. 



Distribution: Europe, western and northern Asia, North Africa, eastern parts of 

 North America, New Zealand.
