MAN'S INFLUENCE ON INDIGENOUS FLORA OF ABERDEEN 237 



C. canescens, L. The same remarks apply to this as to C. dioica. 



C. Modes, Link (C. lavigata, Sm.). Described by Smith in 1804, 

 with reference to examples from " Marshes near Aberdeen, 

 Prof. J. Beattie, Junr.," and recorded from Rubislaw (Harvey, 

 1826); but long extinct within Aberdeen. 



(C. distans, L. Is plentiful on the coast of Kincardineshire, and 

 must have grown by the estuary of the Dee, though there is 

 no actual record of its occurrence there.) 



C. futva, Host. Seems to have become extinct locally about 

 1880, on the cultivation of Stocket Moor. 



Phkum arenaniim, L. " Formerly on Old Aberdeen Links " 

 (Dickie). 



(Deschampsia setacea, Hackel. Grows in so many places on wet 

 moors in the vicinity of Aberdeen that it must have occurred 

 within the parish in similar habitats. As these had been 

 drained and cultivated before the species was distinguished 

 in Britain from D. flexuosa, the absence of any record is no 

 evidence that it did not grow in Aberdeen formerly). 



Avena pubescens, Huds. Recorded from a locality near Old 

 Aberdeen (destroyed by the opening of a sand-pit a good 

 many years ago), and from near Seaton House, this has not 

 been observed within the parish for some time. It is very 

 common beside the Don, so may reappear on the bank 

 within Aberdeen. 



Phragmites communis, Trin. - - Probably common at one time 

 within Aberdeen in swamps, but extinct locally for over half 

 a century. 



Catabrosa aquatica, Beauv. Abundant for a time as late as 1885 

 in sluggish streams and pools beside and on the Links ; but 

 extirpated locally by the filling up of the pools and covering 

 over of the streams. 



Lastrcza montana, T. Moore (L. Oreopteris, Presl.). Found near 

 Ruthrieston by J. Roy in 1864. This is very rare near 

 Aberdeen, though widespread and often common in the 

 uplands. 



Phegopteris polypodioides, Fee. - - " Above Stocket roadside " 

 (Beattie). This is the only record for Aberdeen ; and the 

 fern is rare in the vicinity. 



Osmunda regalis, L. Knight records that it "grew till 1797 in the 

 Marsh, Broadhill." There is no other note of its occurrence 

 within Aberdeen ; and the marsh in question was drained 

 long ago, and has for many years been the site of a cloth 

 factory. At no time common in N.E. Scotland, this fern 

 is now almost extinct in the counties near Aberdeen.
