Crossing over the estuary, and getting on to the 

 bog at Barmouth Junction, may be found Phragmites 

 communis, varying in height from 18 inches to more 

 than six feet. I have a specimen not 20 inches high, 

 with roots and four perfect panicles ; growing along 

 with it is CEuant/ie erocata, Scirpus maritimus, and 

 Typha latifolia. The last-mentioned plants grow in 

 the sluice by the railway-side, until one gets beyond 

 Penman Pool Station from Barmouth. At the Bar- 

 mouth side of the estuary, on the bog may also be

found Radiola millegrana, Osmunda regalis, Carex 

 distans, C. Jlava, var. lepidocarpa, Drosera rotundifolia 

 and intermedia. Going on to Arthog Station, amongst 

 the salt marshes, may be found Statice Limotiium and 

 S. rariflora, also Sueda mariiima and Saticornia in 

 the greatest abundance. CEnanthe Lachenalii and 

 Apium gravelens both grow near Penman Pool Sta- 

 tion, and, retracing my steps to the rocks, near 

 Friog, growing in inaccessible situations, may be 

 seen Asplaiium marinum ; and following the 



coast to the next village, Llangrwyen, near the 

 station, I have found Mentha viridis, M. piperata, 

 and M. gentilis, and also Tanacetum vulgare. 

 By the road, in woods, are large quantities of Hyperi- 

 cum androscemum and Orobanche major. In woods, 

 at or near Barmouth Junction, at Arthog Falls, Tor- 

 rent Walk, and several other places, I have seen 

 Hymenophyllum Wilsoni in the greatest abundance. 

 At the margin of the lakes, on the ascent to Cader 

 Idris, from the Arthog side, I have seen Hypericum

elodes. I have also seen it in swampy ground near 

 Barmouth. I have seen L. selaginoides in several 

 places near small rills near Barmouth ; and Aspletiium 

 Ruta-miiraria grows very fine on an old wall leading 

 from Dolgelly to Penman Pool ; but out of reach, 

 except by a ladder. Amongst mosses, the rarer 

 species I have observed are Entosthodon Templetom 

 and E. ericetorum, Bartramia rigida, Bryum alpwum 

 and B. eloiigatnm, Hedwigidinm imberbe, Zygodon 

 viridissimus and Z. conidens, Campy/opus longipilus
