fruited. It has a much wider European distribution than 

 that species. 



Sisymbrium pannonicum, Jacq., = >S. altissimum, Linn., 

 a plant of central and eastern Europe and western Asia, 

 is widely spread about St. Anne's, and grows in profusion. 

 It is plentiful on both sides of the railway bridge in 

 St. Thomas's Road, in various spots on the sandhills, 

 and is quite naturalised on the coast from Fleetwood to 

 Preston. 



Diplotaxis muralis, DC, is a species fairly frequent 

 at St. Anne's, but is rarely associated with most of the 

 plants enumerated in this list. It has occurred on the 

 sandhills opposite the North Promenade, at the links end 

 of St Andrew's Road South, and it is plentiful upon the 

 cindered roads of St. George's Gardens. Only a small 

 portion of the plants belongs to type nmralis ; by far the 

 larger portion falls under Syme's var. Babingtonii. In 

 1903, upon the extension of Beach Road eastwards, it 

 appeared in the greatest profusion, along with Verbascum 

 Thapsus, Linn., Hyoscyamus niger, Linn., Veronica agrestis, 

 Linn., Veronica Toumefortii, C. Gmel., Oenothera Lamark- 

 iana^ Ser. in DC. 



Lepidium Draba, Linn., is known to me in only one 

 small colony on the coast towards South Shore, near the 

 Ormerod Children's Convalescent Home, upon what was 

 once a waste heap, consisting for the most part of spent 

 hops. It occurs over almost the whole of Europe, and it 

 reached this country nearly a hundred years ago at 

 Ramsgate, in the litter used by the fever-stricken soldiers 

 who returned from the unfortunate Walcheren expedi- 

 tion. 



Lepidium ruderale, Linn., though native to this 

 country, must be considered an alien at St. Anne's, as it
