FURTHEE NOTES ON THE FLORA OF FLINTSHIRE. 



By a. a. Dallman, F.C.S. 



During the past year I have been largely occupied in the 

 investigation of the flora of Denbighshire in its various aspects, 

 and a vast amount of information has now accumulated : of this 

 I hope shortly to give some account. Owing to this large ex- 

 tension of my original undertaking, it has not been practicable to 

 devote very much time to personal field work in Flintshire during 

 this period, although a little has been accomplished. This, how- 

 ever, has been largely compensated for by the kindness of various 

 friends and correspondents, and, as a result, a considerable amount 

 of new material has been acquired, and it may perhaps be as well 

 to place some of this on record. The present contribution is in 

 the nature of a supplementary county list, in the sense that the 

 records quoted represent extensions of distribution, or in some 

 instances additions to the county flora. In preparing this list I 

 have only utilized a fraction of the material to hand, and so it 

 must not be regarded as exhaustive, but rather as supplementary 

 to papers on the suljject whicli I have contributed to this Journal 

 (see Journ. Bot. 1907, 138; 1908, 187, 222; 1910, 40, 53, 90). 

 Consequently the present contribution is entirely and designedly 

 of a systematic character. Work dealing with local ecology, 

 Welsh plant names and plant lore, floral biology, and other aspects 

 of the subject, has occupied much time, but such is purposely 

 excluded. These phases of the undertaking are reserved for 

 detailed treatment in the Flora of Flint and Denbigh, which is 

 in preparation. 



The present affords another pleasant opportunity of more 

 formally expressing my indebtedness to several friends and con- 

 tributors. To Miss F. M. Thomas and Dr. E. J. Haynes Thomas, of 

 Chester, I am under special obligations for much valued help and 

 co-operation. Mr. R. H, Day, as a resident observer, has rendered 

 valuable aid in connection with the vegetation of the Cwm area, 

 and in various other ways. Mrs. New (Backford) and Miss 

 Cummings (Caerwys) are jointly responsible for an acceptable 

 series of records of plants observed in the vicinity of Caerwys. 

 Miss M. Jones, of Tan-yr-ywen, Llanfynydd, has also gone to 

 some trouble to keep me supplied with observations and material
