220 86. GRAivnNA. 



Native. Pascual, &c. The name of Festuca diu-iuscula 

 may be taken to signify a grass that is more or less in- 

 termediate in its characters between F. ovina and F. rubra. 

 But these three names are differently applied by different 

 botanists ; so that almost inextricable confusion and un- 

 certainty would attend any attemj)t to j)arcel out the 

 stations among them in strict detail. Fortunately, for the 

 immediate purpose here required, this speciality of detail 

 is unnecessary; each of the species, real or sujiposed, 

 appearing to occur throughout Britain, when the area is 

 based on the provinces; while the comital distribution 

 may be equally general, except for the littoral species, 

 F. rubra. My own idea of F. duriuscula, is that of a 

 plant not strictly csespitose, but more shortly stoloniferous 

 than F. rubra, with usually plane stem-leaves, growing 

 chiefly in meadows and on hedge banks, and imj)erfectly 

 distinguishable from F. ovina, by its more robust growth, 

 larger panicles, and more awned pales ; but withal pass- 

 ing so close towards, if not into, F. ovina, as often to be 

 undistinguishable by any definite marks or satisfactory 

 character.
