runners. The lower flowers are male, the others are bisexual, the 

 panicles containing 3-6 flowers, being densely crowded. As in most 

 other grasses the stamens are 3, the styles short, and the stigmas 

 feathery. The lowest glumes are i-3-androus, the others 3-androus. 

 The flowers are anemophilous, proterogynous. 



The fruit is enveloped in the glume, and this in long silky hairs, 

 and is light, and adapted to dispersal by the wind.

REED (Phmgnriles communis, Trin.) 



The Reed is a peat-loving plant, luxuriating in peat soil or clay 

 soil, and it is then a clay-loving plant. 



Two stages of Rust fungi, Puccinia phragmitis and P. trailii, attack 

 the Reed, the other stage of each attacking species of Rnvicx in each 

 case. Puccinia magnusiana and Ustilago grandis also infest it, and it 

 is galled by Lipara lucens, Cecidomyia inclusa, Lasioptcris arnndinis. 



Reeds are a regular source of attraction to beetles, such as Phy- 

 tonomus arundinis, and others of the genera Acnpalpns, Europhilus, 

 Bembidiwn, Odacantha, slltophorus, Dromins, Alianta, Homalota, 

 Hygrononoma, Tachyporus, Stenns, Snbcocdnella, Hippodamia, Ani- 

 sosticta, Coccidula, Cereus, Donacia, Crepidodera. It is also visited by
