3 FURTHER NOTES ON THE FLORA OF DENBIGHSHIRE 



assistance in other ways. Most of these records refer to plants 

 seen or collected between 1862 and 1875. Contrary to expectation, 

 the herbarium of John Williams at University College, Bangor, 

 which by the courtesy of Professor E. W. Phillips was kindly 

 examined for me by Mr. E. H. Day, supplies no information on 

 the flora of our area. 



For much of the additional material which has accrued during 

 the past two years I am indebted to the active co-operation of 

 many local botanists and observers. To Miss F. M. Thomas and 

 Dr. E. J. Haynes Thomas, of Chester, I am under a special obli- 

 gation for much valued help in many ways. Thanks are also due 

 to Miss E. Foulkes Jones, also of Chester, Mrs. Evans Jones 

 (Dyserth), Mrs. New (Backford), Mrs. Phillips (Caergwrle), Miss 

 C. E. Euddy (Ehyl), and Miss C. I. Thomas, of Chester. Particular 

 acknowledgment is due to Mr. J. L. Harnaman (Derwen) and Mr. 

 J. M. Harnaman (Alvanley). I have also to thank Mr. E. H. Day 

 (Cwm), Dr. H. Drinkwater (Wrexham), Mr. G. Loftus (Liverpool), 

 Dr. W. B. Eussell (Colwyn Bay), Mr. J. Southworth (Stoke-on- 

 Trent), Mr. C. Waterfall (Chester), and Mr. W. E. Williams, of 

 Eglwys Fach. There are several genera, the occurrence and 

 distribution of which are only very imperfectly worked out as 

 yet, and I would commend these to the notice of local workers. 

 Examples of this are provided by Rosa, Carex, Potamogeton, Rubus, 

 Salix, and Callitriche. 



During the summer of 1911 I resided in the county for about 

 a month. The picturesque and secluded little hamlet of Eglwys 

 Fach (= "Little Church"), in the Conway Valley, proved a 

 convenient centre for exploring some interesting country, of which 

 little was known. The underlying rocks hereabouts consist of 

 Denbighshire Grit and Wenlock Shale, formations typical of a 

 large area of the county. Such plants as Lejridium Smithii, Rubus 

 IdcBus, Sedum anglicum, Jasione montana, Scabiosa succisa, Cam- 

 imla rotundifolia, and Cotyledon Umbilicus, appear to be generally 

 associated with these formations in Denbighshire. 



Leaving Eglwys Fach, I made my headquarters for the last 

 fortnight of August at Yspytty Ifan (= " St. John's Hospital "). 

 This remote spot is situated towards the south-western extremity 

 of the county near the source of the Eiver Conway and on the 

 border line of Denbighshire and Carnarvon. Immediately around 

 Yspytty Ifan and between here and Cerrig-y-Druidion the Silurian 

 rocks of the Eglwys Fach area have given place to the older 

 Ordovician System, and the change finds reflection in the topo- 

 graphy and vegetation hereabouts. I found the details of the 

 geology of the district somewhat difficult to follow, but the 

 formation seems to be of the Bala type in the main. The Arenig 

 series is also represented but to a lesser extent. Amongst note- 

 worthy components of the flora of this area, Trollms europceus, 

 Viola lutea, Vicia Orobus, Rubus Idceus, Serratula tinctoria, Poly- 

 2)odium polypodioides, and Equisetum sylvaticum are of frequent 

 occurrence. Spircsa salicifolia and M'nnulus Langsdorffii are 

 thoroughly established and plentiful in places along the valley
