POA SEROTINA 

 (Late Meadom Grass). 



In comparison with P. pratensis and P. trivialis this 

 variety is later in flowering and in ripening seed. The plant 

 is successful on almost all kinds of soil, especially on rich 

 moist land. For hay it is a valuable grass, producing an 

 abundance of foliage early in the season. The aftermath is 

 not very great, but in permanent pastures it has the merit of 

 growing freely between the period of ripening and after-yield 

 of most other grasses. 



Quite a year is required to develop strong plants of Late 

 Meadow Grass, and for this reason it cannot be recommended 

 for alternate husbandry. True seed is difficult to obtain. 



In the absence of the flowering panicle Poa serotina can 

 always be distinguished from Poa nemoralis by the short blunt 

 ligule. 



POA AQUATICA 



( Water-Meadoiv or Sweet Reed Grass). 



Adapted for low-lying land subject to floods, nutritious, 

 and generally liked by cattle. In the Fen districts it forms 

 a large part of the herbage, and yields abundant crops of hay. 

 From the name it wall be understood that this grass is specially 

 suitable for water-meadows, and seed may also be included 

 in permanent mixtures for undrained clay. The flowering 

 occurs in July and August. 



Poa aquatica is also known as Glyceria aquatica, and is 

 common in the water-meadows of the South of England, 

 where the closely aUied Floating Sweet Grass, Glyceria 

 fluitans, is also frequently found.
