Asplenium viride. In crevices of the rocks at the upper Cilhepste waterfall, near Pont 

 Nedd Vechn, and at Darran yr Ogof, near Ystradgunlais, (Dillwyn). 



— -^^— marinum. On rocks and walls near Oystennouth, and along the coast of 

 Gower, common, (Dillwyn). Very plentiful in Bacon's Hole. 



■ Ruta-muraria. Common on walls near Swansea. 



lanceolatum. Town Hill, near Swansea. 



Adiantum-nigrum. Park and Pennard. 



Athyriwn FUix-femina. Town Hill. 



Pteris aquilina. Town Hill. 



Lomaria spieant. Common in the hedges. 



Adiantum Capillus-Veneris. Common on the cliffs of lias at the eastern end of the 



county. I have never seen it on mountain limestone, or nearer to Swansea than 



Dunraven, (Dillwyn). 

 Osmunda regalix. Common and in great luxuriance in ditches hy the road-side and 



other moist places. In the summer of 1839 I found, near Cwmbola, the root of 



one plant measuring at least between four and five feet in circumference. 

 Botrychium Liinaria. On the lawn in front of Penrice Castle, and occasionally found 



in Nicholston Wood, and other woods in the neighbourhood, (Dillwyn). 

 Pilularia globulifera. About the borders of Llynfach, on the mountain eastward 



above Aberpergwm, (Dillwyn). 

 Equisetiim Jfuviatile. Cromlyn Bog and other bogs in the neighbourhood. 



arvense and palustre. Near Singleton. 



sylvaticum. Near Cwmbola; Drymma wood, between Neath and Swansea.

to be abundant. 



Andrcea alpina. About Llyn Vach, near Aberpergwm. 



Dyphyscium foliosum. Plentiful on rocks at the waterfalls about Pont nedd Fiscke, 

 and at a small fall on Bryn Cois ; near Cadoxton, (Dillwyn). 



Tetraphis pellucida. On a decaying tree near Pont Nedd Vechn ; and it has been 

 found by Mr. Woods, with Funaria Muhlenbergii, about the ruins of Caer- 

 philly Castle, (Dillwyn). 



Weissia verticillata. Found by Mr. Woods on the rocks about Barry Island, and I 

 suspect that a species which has been gathered from the rocks in Gower, is the 

 same. I believe Grimmia maritima has also been found in this neighbourhood. 



Trichostomum polyphyllum. On rocks about Pont Nedd Vechn, and several other 

 places, (Dillwyn). 



Dicranuvi cervieulatum. On dry turfy banks in several places, and is probably com- 

 mon, (Dillwyn).

 me to be different from T. unguiculata, (Mr. Ralfs).

 bourhood of Pont Nedd Vechn, (Dillwyn). 



Bryum ventricosum. About Uscoed Hendry, near Ystradgunlais, and the waterfalls
