HOURS AMONG ROCKS AND CLOUDS. 371 



Prunus padus. — In woody spots towards Plinlimmon. 



Vaccinium vitis-idcea. — In the turbary on Plinlimmon, above the source of the 

 Severn. 



Campanula hcderacea. — Very abundant on the moist bank in an Oak-wood 

 close to the Machynnleth-road, about two miles from Llanidloes ; in a 

 bog in a hollow of the hills above the Clwddach, nearer the town on the 

 same road ; and on the Plinlimmon bogs above Blaen Hafren. Exqui- 

 sitely beautiful wherever it appears. 



Hieracium maculatum. — On the Slate-hills above the Chaddach. 



H. umbellatum. — Very common on the Heathy declivities around. 



Myosotis repens. — In ascending Plinlimmon from the Begalyn Pool I caught a 

 glimpse of some clusters of light blue flowers in the middle of a quaking 

 bog, to which they gave an aspect of beauty, though almost inaccessible 

 from the deep waters around them; by baring my arm, however, I 

 managed to obtain a handful, which, on examination next morning, proved 

 to be the above. The base of the stem is decumbent, throwing out 

 numerous stolones with roots, which multiply the plant abundantly. 

 Stem and stolones with numerous spreading hairs. Leaves Ungulate, 

 hairy, especially at the base, the lower ones attenuated into a channeled 

 footstalk, the rest sessile, often decurved. Racemes not leafy in my 

 specimens. Flowers on long pedicels, with close adpressed hairs, recurved 

 when in fruit, and thrice as long as the calyx. The latter is deeply 

 divided, with adpressed hairs, the apices of the sepals connivent upon the 

 very smooth fruit. Petals azure, light purple towards the base, with a 

 brilliant yellow eye. Not so large as in M. palustris. I have given the 

 above particulars, taken down at the time, that no mistake might be 

 imagined with regard to- my plant, which was first distinguished by Mr. 

 Don, in Scotland, and since found in Sussex by Mr. Boerer, by Mr. Don 

 in Kent, and Mr. Backhouse in Yorkshire. The sketch I made of the 

 Plinlimmon specimens agrees precisely in character with the plate in Eng. 

 Bot., Supp., t. 2703, but my stolones are far more numerous. 



Calluna vulgaris, var. — With pure white flowers, in a natural wood above 

 Can Coed on the Severn. 



Anagallis tenella. — A common concomitant of the bogs in the vicinity. 



Scutellaria minor. — Bog on the hills above the Clwddach, plentifully. 



Empetrum nigrum. — Birch-wood on the Machynnleth-road. 



Platanthera chlorantha. — In the same wood. 



Narthecium ossifragum. — Very abundant in various bogs. 



Triodia decumbens. — Plentiful on the Slate-hills about Llanidloes. 



Hymenophyllum Wilsoni. — On some rocks near the Rhydol, at a plank over a 

 dangerous gulph of the river called Pont Bren.
