Manchester Memoirs, Vol. Hi. (1908), No. I,"*. 3 



Mr. Frederick Fuller, of Latchford, and Mr. Ralph 

 Burrows, of Grappenhall, have rendered some assistance 

 in field work. 



For help kindly given in the identification of speci- 

 mens I am indebted to the Director, Royal Gardens, 

 Kew ; Mr. Charles l^ailey, M.Sc, St. Anne's-on-the-Sea ; 

 and Mr. Eric Drabble, D.Sc, Liverpool University. 



Except where otherwise stated, I am responsible for 

 all the records, having either seen the plants in situ, or 

 examined the specimens and localities. 



The numbers 58 and 59 placed in front of the 

 localities refer to the vice-counties, Chester and South 

 Lancaster, of H. C. Watson's " Topographical Botan}-." 



The plants enumerated in this list follow the nomen- 

 clature and sequence of the " London Catalogue of 

 British Plants," loth edition, 1908. Species marked with 

 an asterisk are new to the Warrington district. 



Thirty of the species here recorded are now extinct. 

 They belong mostly to the Arpley goc ds-3'ard and 

 Slutcher's Lane area, both within the Borough of War- 

 rington. The Slutcher's Lane locality was destroyed 

 some years ago by extensions of the L. & N.W. railway 

 sidings. I have searched the surrounding area more than 

 once, without finding the slightest trace of the fine series 

 of aliens recorded by Mr. Billups. 



Many plants, included as aliens in Mr. S. T. Dunn's 

 " Alien Flora of Great Britain," are purposely omitted 

 from this list, as being of general occurrence in the 

 country, such as Fuumria pallidiflora, Jord. ; Cociikarin 

 Arnwracia, Linn. ; Brassica arvensis, O. Kuntze ; Lepidiiuu 

 heteropliylluni, Benth. var. canescens, G. & G. ; LycJinis 

 GitJiago, Scop. ; GeraniuDi cohnnbimnn, Linn, ; Pismii 

 sativum, Linn. ; Fceniailum vnlgare, Mill. ; Symplwri- 

 carpus racemosus, Michx. ; ChrysantJienmvi Partlienium,
