BOG PLANTS. 



Most of these grow on Cars Gochno, an extensive morass six miles 

 north of Aberystwith, at the mouth of the Httle river Leary, and well 

 deserving examination. 



Drosera longifolia 



Hypericum elodes 



Comarum paliistre 



Vaccinium Oxycoccus 



Andromeda polifolia 



Campanula hederacea. This little plant 

 beautifully adonis the bogs on Plinlim- 

 mon, by the course of the infant Severn. 



Anagallis tenella 

 Pedicularis palustris 

 Scutellaria minor 

 Myrica Gale 

 Nai'thecium ossifragum 

 Rhynchospora alba 

 Eiiophorum vaginatum 



ROCK PLANTS. 



Corydalis claviculata 



Arabis hivsuta 



Viola lutea, on the hills about the Devil's 

 Bridge 



Cotyledon Umbilicus 



Sedum anglicum, very abundant on the 

 castle rock 



Sedum Forsterianum. The plant which I 

 gathered on a rock at the foot of the 

 Rheidol Fall in 1837, and which flow- 

 ered in a pot in my garden in June, 

 1839, differs considerably from the fi- 

 gure in ' Eng Bot.' 1802, and comes 

 nearer S. glaucum, 2477, the petals be- 

 ing narrow and almost linear, the calyx 

 deeply cut, its segments sharp-pointed, 

 and all the leaves with acute points. 

 The barren branches are elongated, 

 with the leaves curved or patent. Ne- 

 vertheless, I conclude it can only be a 

 variety of S. Forsterianum, which in- 



deed was gathered by Mr. Forster at 

 this very spot; and perhaps S. glaucum 

 itself may not be very difi"erent. 



Crithmum maritimum, very sparingly 



Ligustrum vulgare, on the castle rock ; and 

 I have generally found this plant on 

 the maritime rocks of South Wales. 



Linaria repens, on the slate-rocks of Con- 

 stitution-hill, very luxuriant and beau- 

 tiful. 



Origanum vulgare 



Cistopteris fragilis, on the Devil's Bridge 

 and neighbouring walls, plentiful. 



Aspidium Oreopteris, on the descent to 

 Pont Bren 



Hymenophyllum Wilsoni, rocks at Pont 

 Bren 



Lycopodium clavatum, alpinum and Sela- 

 go, all very abundant on Plinlimmon, 

 twelve miles N.E. of Aberystwith. 



MARSH PLANTS, 



Spergula nodosa Utricularia minor 



OEnanthe peucadanifolia Callitriche autumnalis 



crocata Triglochin palustre 



Lobelia Dortmanna, Teivy Llyn, S.E. of maritimum 



Aberystwith Juncus maritimus 

 Samolus Valerandi 



The above (Lobelia excepted) are found at Borth Marsh, six miles 

 North of Aberystwith.
