ripe, in common with, and in a much greater degree than this 

 one ; but the lower portion of culm, close at the root, and 

 the sheaths of the root-leaves of the F. rubra have a deep 

 reddish -brown colour, and the term rubra very properly 

 applies to these. The awned variety of the Festuca ovina 

 is most deserving of the name rubra, as denoting such a 

 property of the panicle.

The above details may be sufficient to shew that the creeping 

 fescue has no superior merit over those species it resembles in 

 habits to compensate for the impoverishing effects of its creeping 

 roots to the soil. The first and second vears of its growth from

 of its three-year old produce. After the second year the produce
