It flowers in the second week of July, and the seed is ripe about the middle of August. 



Poa compressa, var. erecta. Upright Flat-stalked Meadow-grass. 



Ql^s^ — ^This differs from the fonuer variety of Poa compressa, in having culms more uprioht 



some- 



less compressed, and produced in greater quantities. Tlic colour of the leaves is 

 v^hat glaucous; they grow more upright than those of the other variety. Root creepinp- 

 like that of the former, hut furnished with numerous fibres, which supply culms and

leaves in abundance, the plant soon forms a close covering to the ground, while the other 

 remains in a scattered state. 

 Experiments, — ^At the time of flowering, the produce from a light sandy loam, is.

This variety of the Flat-stalked Meadow-grass affects a soil of a moister, and more rich 

 nature, than the first-mentioned variety. It grows more close, forming a pretty good sward;

 variety, and the produce of foliage in the spring is likewise inferior. The produce of latter- 

 math IS greater than might he expected of a grass with short slo^v-growing foliage, but the 

 plant has the property of sending up flowering c^ms till a late period of the season, and the 

 latter-math produce consists chiefly of these. What w.« «.;,! .^..^..'no- the merits of the first
