[Names of plants in italics, except as synonyms within curved brackets, denote 

 that the plants were certainly introduced into Scotland by man. f after a 

 district -number denotes introduction by man into the district; "cas." 

 denotes casual occurrence, and "esc." evident escape or outcast from culti- 

 vation, both being due to man's agency. Square brackets enclosing the 

 name of a plant or a district-number denote that the record was made in 

 error. ? after a district-number denotes, at least, need of confirmation ; 

 after t it denotes doubt as to whether the plant owes its presence in the 

 district to man.]
