254 17. ACERACE.E. 



Hypericum barbatum, Linn. 



Area * [15]. 



Incognit. Said to have been found " by the side of a 

 hedge neai- the wood of Aberdalgy, in Strath Earn," Perth- 

 shire, by Mr. Don. No other botanist having met with 

 examples, we cannot suppose this easily-seen species to 

 have been either native or naturalized in the one locality ; 

 and in which it is now probably extinct.

Native. Sylvestral and Septal. On the authority of 

 Lightfoot's Flora Scotica, this Acer extends northwards to 

 Kinfauns, near the town of Perth, and to Ai'dmaddy, in 

 Nether Lorn. Mr. Montgomery reports it from Castle 

 Semple, Renfrewshire ; and Patrick records its existence in 

 "woods and hedges," in Lanarkshire. All these, it is to be 

 feared, are very suspicious localities, and to which the spe- 

 cies is likely to have been introduced. In the Edinbm-gh 

 Catalogue it is given as a doubtful native of the Forth 

 coimties. In the Flora of Berwick-on-Tweed we find it
