THE GKASS FAMILY. 



11. Roughish Poa. Poa trivialis, 

 Linn. (Fig. 1227.) 

 (Eng. Bot. t. 1072.) 



Very near the meadow P., but there 

 are no creeping scions ; the etems are 

 usually taller and more slender ; the 

 ligula of the leaf longer ; the panicle 

 more slender, often 6 inches long, with 

 slender, spreading branches ; the spike- 

 lets have seldom more than 3 flowers, 

 and usually only 2. Flowering glumes 

 as in the meadow P., except that the 

 lateral nerves are much more conspi- 

 cuous. 



In meadows and pastures, with the 

 same geographical range as the meadow 

 P., and at least as common. Abundant 

 also in Britain. Fl. summer, commencing 

 early.

A perennial, 1 to 2 feet high, tufted 

 or slightly creeping at the base, erect,

 Spikelets compressed, lanceolate or 

 ovate, w T ith 2 to 5 flowers in each, and

 Flowering glumes rather more than a

 in the last two species, with a line of 

 small silky hairs on each side and an- 

 other on the keel.
