Prickly Twig Rush is a char- 

 acteristic bog plant which grows 

 especially in lowland districts near 

 the sea, and most uniformly in E. 

 Anglia. 



The first Greek name suggests 

 (as does the English one) the rigid 

 prickly character of the head of the 

 plant. 1 1 has rounded stems, which 

 are erect, stout, leafy, and smooth, 

 with leaves which are long, rigid, 

 3-anglecl at the tip, rough on the 

 margin. 



The flowers are borne in a 

 dense corymb-like compound cyme, 

 axillary or terminal, which is con- 

 tracted, the flowers being collected 

 One nut only is fertile. 

 Prickly Twig Rush is 3 ft. in height. The flowers are in bloom in 

 July and August. The plant is perennial, increased by division. 



The flowers are pollinated by the wind, bisexual, or the lower male.
