[.Scheuchzeria palustris , L.—I fear that this species is now lost as 
a Perthshire plant. Careful and repeated search for it has been all 
in vain. I only mention it here as it is an example of a plant whose 
distribution is not continuous, since it makes a jump from Yorkshire 
to Perthshire; and, if it did so, why not the more widely spread 
Butomus .?] 
Bromns sterilis , L.—Although no doubt has been expressed as to 
this grass being indigenous, it seems to me to be a very doubtful 
native with us. A similar suspicion is attached to Bromus race- 
mosus, L., Trisetum flavescens, Beauv., and Poa compressa, L., and 
perhaps also Lolium perenne , L.
