Diganwy, where we had previously gathered it sparingly from the 

 ivy on the west cliff. The character of the anthers of O. Hederse, — 

 ovate, prolonged, acute, conspicuously awned, even to the unassisted 

 eye, — appears to us to be suflScient at once to distinguish it fi'ora O. 

 minor, whether compared in a fresh state or as dried specimens. On 

 the road from Carnarvon to Llanberis, Cotyledon Umbilicus presents 

 itself the whole way, and is still found at greater distances eastward. 



Just before the village of Cwm-y-glo, at the entrance to the Pass of 

 Llanberis, the road intersects a bog of considerable area. A cursory 

 examination of a small corner on the right-hand side of the road gave 

 us Hypericum elodes (abundantly), Scutellaria minor, Menyanthes 

 trifoliata, Drosera rotundifolia, Myrica Gale, Rhynchospora alba, Nar- 

 thecium ossifragum, &c. Just beyond the village, the queenly Nym- 

 phaea alba was in full flower, in the ditches filled by the drainings of 

 the bog. Here we also noticed Comarum palustre, and believe the 

 locality would amply repay a diligent investigation. Alisma natans 

 was in flower in Llyn Padara, on the south side, near the Dolbadern 

 Castle end. Lobelia Dortmanna was coming into fruit. We noticed 

 it also in the following lakes, viz. : — Gwynant, Ogwen, Idwall, and 

 Mymbyr. To these, Mr. Pamplin adds Llyn-y-cwm. 



The ascent of Snowdon from Llanberis, making a detour to the foot 

 of Clogwyn-dur-Arddu, gave Arabis petrsea, Oxyria reniformis, Rho- 

 diola rosea, Saxifraga stellaris, and Empetrum nigrum, in fruit. Hy- 

 pericum Androsaemum and Serratula tinctoria have stations about a 

 mile on the road from Beddgelert to Pen-y-gwryd. About half a mile 

 from the latter place is a patch of Anagallis tenella, growing on a wet 

 bank which overlooks the wall ; (also along streamlets on either side 

 of Y Glyder Fawr, Mr. Pamplin). The little way-side inn constituting 

 Pen-y-gwryd is well worth the attention of the botanist, from its situ- 

 ation, which gives immediate access to either side of the pass. There 

 is no pretension about the place ; but those who may put up there, 

 will find a hearty disposition to make them comfortable. It was here 

 that we had the only opportunity, during our trip, of drying our " Ben- 

 tall " before a fire. 



Leaving Pen-y-gwryd in the morning, we steered our course due 

 north, for Glyder Fawr, the ascent of which is about equal to that of 

 Snowdon in time and labour. Not a single plant did it yield us. 

 The prospect from the summit of the ridge, however, amply repaid 

 the ascent, and would have done so had it simply included the black 

 waters of Llyn Idwall at our feet, with the valley of Nant Francon 

 beyond, leading the eye as far as Bangor and Anglesea. After going
