here noticed, is generally referred to H. sylvaticum or H. vulgatum, 

 Fries, while if it must be joined to something else, I should agree with 

 the late Mr. Bowman in placing it with H. raurorum. 



About the fissure down which we scrambled, 1 gathered some spe- 

 cimens of Scabiosa Columbaria, taller than any I ever before met 

 with, and therewere many of them finely in flower. " Scarcely a foot 

 high," Hooker and Arnott observe in their ' British Flora,' and indeed 

 in dry calcareous spots they are often only three or four inches in 

 height ; but on these trap-rocks they were flourishing more than two 

 feet in altitude, and were fairly entitled to a major''s commission. 

 Digitalis purpurea was extremely plentiful all about the Breidden 

 hills. Perched on the rocks bounding the precipitous descent 1 have 

 mentioned, were many trees of the Pyrus Aria, with unripe fruit, but 

 the crags on which they waved their silvery foliage were so abrupt, 

 that I had considerable difficulty in mounting them to obtain speci- 

 mens. 



T need not now enumerate the more general plants of rocky places 

 which I noticed here, such as Cotyledon Umbilicus, Sedum Telephium, 

 &c., for on this first visit having become rather tired with my clamber- 

 ing efforts, and the day declining, 1 fell back upon the little hostel of 

 the ' Plough and Harrow,' and in the silence of twilight scudded back 

 to Welchpool. 



On examining carefully the plants collected on ray first expedition 

 to the Craig, T found I was defective in two or three of its greatest 

 rarities, and concluding therefore that I must have missed one of the 

 most favourable points, I once again started on the morrow for 

 another perambulation. This time I went alone. Taking the route 

 up the ravine between the Craig itself and the steeps of Moel-y-Golfa, 

 I was struck by the appearance of the southern precipices of the for- 

 mer, producing for some distance up the hill a crumbling talus of 

 loose stones, surmounted by very steep and almost inaccessible crags. 

 I resolved to examine this, and soon lighted upon Geranium sangui- 

 neum, growing pretty plentifully among the stones, though only a 

 few specimens were now in flower. Persuaded I was now on the 

 right scent, I cautiously peered upwards, and mounting the glacis, 

 kept working my way among the disjointed stones as well as I could, 

 though the broken fragments shelving downwards rendered it rather 

 difficult to stand. Having surmounted the talus, I was I'ewarded by 

 at once stumbling upon Potentilla rupestris, which I was particularly 

 anxious to find, though now in seed, and in a great measure burnt 

 up. There were several colonies of this local plant nestled among the
