 panicles containing 36 tlowers, being densely crowded. As in most

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 pJiragtiiitis -m-vX P. tiaiPii, attack 

 the Reed, the other stage of eacli attacking species of Rniiicx in each 

 case. Piiccinia magnitsiana and Ustilago gi-aiidiis also infest it, and it 

 is galled by Lipara liicciis, Cecidoinyia inc/usa, Lasioptcris arnndinis. 



Reeds are a regular source of attraction to beetles, such as P^hv- 

 lonoviJis arundjnis, and others of the genera Aciipalpus, Eitrophiliis, 

 Bembidiiini, Odacantha. yEtophorns, Droii/ins, A Haul a, lloiiialota,
