POA conipressa, var. erecta. Upright Flat-stalked Meadow- 

 grass. 



Ohs. — This differs from the former variety o{ poa cumpressa 

 in having cuhns more upright, less compressed, and 

 produced in greater quantities. The colour of the 

 leaves is somewhat glaucous ; they grow more upright 

 than those of the other variety. Root creeping like 

 that of the former, but 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 15,654 lbs. per acre. 



The produce of latter-math is 4,764 lbs. per acre. 



This variety of the flat-stalked meadow-grass affects a 

 soil of a moister and more rich nature than the first-men- 

 tioned variety. It grows more close, forming a pretty good 

 sward ; the roots are less inclined to creeping. It sends up 

 a great quantity of flowering culms, which constitute the 

 principal weight of the produce, and remain green and suc- 

 culent long after the seed is ripe ; on this account the seed 

 crop contains so nmch more nutritive matter than the flower- 

 ing crop. Tt is a week or ten days later in flowering than 

 the former variety, and the produce of foliage in the spring 

 is likewise inferior. What was said respecting the merits of 

 the first variety may also be said of this one ; for though its 

 produce be greater, and form a better turf, yet it is inferior 

 in early growth, and in the produce of foliage. 



It flowers in the end of July, and the seed is ripe about 

 the beginning of September. 



LOTUS corniculatus. Bird's-foot Trefoil, Bird's-foot Clover.
