NOTES ON THE FLORA OF DENBIGHSHIRE O 



Williams (presented to University College, Bangor, by his son) 

 and Mr. W. Whit well's herbarium are behoved to include numer- 

 ous Denbighshire records which yet require collation ; this also 

 applies to the collection preserved at St. Beuno's College. 



Much information has been atforded by the kind co-operation 

 of various local botanists and observers, and in this connection 

 special acknowledgment is due to Miss F. M. Thomas and Dr. 

 E. J. Haynes Thomas, of Chester. I have also to thank the Misses 

 Payne of the same city for a list of ahen and other species 

 observed by them in the Glyn Ceiriog district in 1900. Mrs. New 

 (Backford) and Miss H. M. Williams (Aston) have contributed a 

 number of records, chiefly from the Creuddyn Peninsula. Dr. 

 W. B. Eussell (Colwyn Bay) very generously placed his note- 

 book on the flora of the Colwyn Bay area at my disposal, besides 

 rendering assistance in other ways ; his notes and records extend 

 over a period of many years and have proved very useful. Dr. 

 H. Drinkwater, of Wrexham, has supplied some records mainly 

 from that neighbourhood, while Mr. W. Hodge (Northwich) has 

 communicated some notes in reference to plants observed by him 

 chiefly in the littoral portion of the county. Mr. J. M. Harnaman 

 (Alvaniey) and Mr. Hodge are jointly responsible for a number of 

 records of plants for the Llandegla and Euthin districts. Very 

 material aid has been rendered by Mr. W. Whitwell in various ways. 

 The records credited to the late J. J. Ogle are taken from an un- 

 published paper entitled " Botanical Notes of Hohday Stays at 

 Old Colwyn," which he read at a meeting of the Liverpool Botani- 

 cal Society in 1909. 



Last summer I spent a month in the county with a view to 

 systematically investigating the flora, and I was also able to 

 obtain some interesting observations in connection with local 

 floral biology. I further succeeded in obtaining much new material 

 bearing upon Welsh plant lore and local plant names, but in the 

 present paper I have confined myself to the systematic aspect of 

 the work. Cyffylliog was chosen as a centre for three weeks in 

 August, this being near the middle of the county and in an area 

 of which scarcely anything appeared to be known in regard to the 

 flora. I then descended to the southern part, where I spent a 

 week at the commencement of September in the Tanat Valley in 

 company with Mr. G. Loftus, with Llanrhaiadr-yn-Mochnant as 

 centre. A bicycle was taken with a view to facilitating the in- 

 vestigation of the extensive area, the greater portion being far 

 from any railway ; this proved useful on some occasions, but 

 owing to the hill country and the wretched nature of the by-roads 

 was of less advantage than I had anticipated. Owing to the 

 result of an accident, which precluded much walking or climbing, 

 I found it difficult to accompHsh much during the last week or so, 

 and consequently the detailed investigation of the mountainous 

 country between the Tanat and Dee Valleys has had to be post- 

 poned. During the time I covered a distance of approximately 

 seven hundred and fifty miles in the course of my excursions, 

 and, having regard to frequent adverse weather and other cir-
