370 HOURS AMONG ROCKS AND CLOUDS. 



Hypericum dubium. — On the Aberystwith-road, and in a natural Birch-wood 

 in the Clwddach valley. 



H. elodes. — In a bog in the hollow of the Heathy hills before-mentioned. 



Androscemum officinale. — In the woods at the Devil's Bridge. 



Arenaria rubra. — Abundant on the Machynnleth-road. 



Stellaria glauca. — In various moist hedges. 



Acer campestre. — Extremely common, more particularly near Welchpool. 



Sedum Anglicum. — On the Schistose rocks above the three-arched bridge, and 

 on the banks of the Rhydol, near its fall. , 



S. Forsterianum. — In moist crevices below the Rhydol fall, but not very 

 abundantly. 



Saxifraga stellaris. — Side of the Severn above Blaen Hafren, and on the drip- 

 ping rocks above the Rhydol Pool on Plinlimmon, a few specimens still 

 beautifully in flower. 



Ulex nanus. — Hills on the Machynnleth-road, where one was completely 

 golden with this plant. 



Ornithopus perpusillus. — On the Slate hills. 



Rubus idceus. — Very common in rocky and woody spots about Llanidloes, in 

 every direction. 



R. suberectus. — This beautiful Bramble is an invariable accompaniment of the 

 moist sub-alpine tracts of Wales, and, whether displaying its pure white 

 flower, or bright red fruit, cannot fail to attract attention and admiration. 

 I gathered many fine specimens in the thickets on the Machynnleth-road, 

 and it gems the woods to the very base of Plinlimmon. 



R. affinis ? — I am afraid this Bramble can hardly be satisfactorily distin- 

 guished from R. suberectus. At all events botanists seem much puzzled 

 with it. It is R. nitidus of Smith, and, according to Dr. Lindley, R % 

 plicatus of Mr. Bobrer in Supp. to English Botany. Some of the varieties 

 of R. rhamnifdius, too, so nearly resemble it, as to deceive the most 

 careful observers. 



R. Kohleri ? — I met with a glandular Bramble here, which I must leave in 

 the uncertainty that still envelops the members of this difficult genus. 

 It seems different from R. rudis, though the latter is combined by Mr. 

 Borrer with R. Kohleri. 



Rosa spinosissima. — In some abundance by the side of the road, just beyonc 

 the one-arched bridge on the way to Glyn Hafren. 



R. villosa. — Further on in the same direction. 



R. canina Forsteri. — In a hedge on the same road. 



Pyrus aucuparia. — Several fine old trees glistening with red berries in the 

 lanes round the town.
