Agrostis pahstris): it approaches nearest to var. % (angustifohaj , but the panicle is spea,. 

 shaped, loose when in flower, and contracted so much when in seed, as to resemble a spike 

 and is If a whitish grey colour : it is essentially distinguished from the others by the W-ger 

 valve of the blossom being furnished with a minute awn, which rises a little above its middle, 

 and reaches to the top of the valve : the awn is straight, and pressed close to the back of tbe 



valve. 



The above characters of distinction, and the specimens which are afterwards given to lUus- 



trate them, were taken from plants raised from seed on the same, and on different soils, that the 

 plants were found naturally growing on ; the characters of the wild plants were compared with 

 those of the cultivated ones, and what remained constant after these changes of circumstances, 

 are the above. It is easy to conceive the change that takes place in the general appearance of a 

 plant when brought out of a wet ditch, and cultivated on a dry exposed soil, or from under the 

 shade of trees on a poor sand, and planted out on a rich loam with full exposure to sun and air. 

 Characters, therefore, that change with these changes of circumstances, tend more to perplex 

 tlian enlighten, and may therefore be better omitted.
