Native. Glareal, Rupestral. A difficult species, too 

 closely resembling F. bromoides ; to which latter several 

 of its recorded stations very likely belong. I have seen 

 specimens only in or from Surrey, Suffolk, Norfolk, 

 Gloucester, Hereford. According to Mr. George Don 

 and Dr. Walker Arnott (Flora Scotica, 1821) it grows even 

 so far north as Forfarshii'e ; which is improbable, unless 

 the F. pseudo-Myurus be truly a variety of F. bromoides ; 

 on which latter supposition the variety may perhaps occur 

 in any county where the typical fonn will thrive. In one 

 attendant circumstance or other, however, I find grounds 

 to think that all the Scottish stations, and most or all of 

 those in the northern provinces of England, have been 

 recorded erroneously, through apj)ljing the name of Myu- 

 rus to F. bromoides. Principally or more frequently on 

 walls, which make an artificial site of an intermediate 

 character between ' glareal' and ' rujjestral.'
