ALIEN PLANTS NEAR EDINBURGH 97 



a railway bank (garden outcasts), in nurseries (weeds), and at 

 Warriston (an old record). These are marked 2A. 



District No. 3 (the Esk mouth at Musselburgh) likewise 

 yielded nothing new ; but by the side of the Esk, from its 

 mouth to the railway bank at Inveresk, several additions were 

 noticed. These are marked 3A. 



No. 4 (Murrayfield) yielded only one that has not 

 already been recorded. 



No. 5 (Leith Docks) has since last year undergone 

 much alteration, but still remains very productive. Sisym- 

 brium Irio, L., and vS. altissimuin, L., have almost disappeared 

 owing to the laying of rails ; Melilotus indica, All., and 

 Matricaria discoidca, DC., are as abundant as ever ; Brassica 

 alba, Boiss., Galium tricorne, Stokes, and Lolhim temulentuni, 

 L., were very abundant ; and Hordeum mariimni, Huds., and 

 Festuca ligustica, Bert, were surprisingly plentiful. 



No. 6. To these five localities a new one is now added. 

 It consists of Craigmillar Castle and Quarry : in and about 

 the Castle plants still abound which are supposed to have 

 been introduced in the time of Queen Mary ; and in the 

 Quarry, partially used as a receptacle for refuse, many garden 

 outcasts are flourishing. 



The relative abundance of each species in each locality 

 is again expressed, as kindly suggested by Professor Trail, 

 by the Greek letters placed after the numbers of the localities 

 thus : a = once found ; /3 twice or thrice, but rare ; 7 = 

 neither rare nor frequent; 8 = frequent ; e = abundant; and 

 the -j- is used to indicate some doubt as to the identity of 

 the species.
