106 Prof. R. Graham's Account of a Botanical Tour 



ter ; Rosa arvensis, Nepeta cataria ; Senecio tenuifoliuSj abundant 

 also further south, but native, as far as is known, in very few 

 locaUties in Scotland ; Sedum dasyphyllum, on walls at Conway ; 

 Calamintha officinalis, Foeniculum vulgare (also plentiful near 

 Weymouth and in Jersey), Orohanche barbata in profusion, and 

 Verbena officinalis. 



The Welsh mountains, at least in August, possess very little 

 interest to a Scotch botanist. The alpine species are few com- 

 pared with the vegetation of the Grampians, and the number of 

 specimens even of common species is very small. The valleys, 

 however, contain in abundance several plants which are rare in 

 Scotland, or which do not exist there as natives. Among these 

 are Poterium Sanguisor^ba, Serratula tinctoria, Campanula hede- 

 racea. " Thalictrum minus is abundant in several places in Scot- 

 land, but we found it at the Devil's Kitchen, at a much higher 

 elevation than I ever recollect seeing it before, except in Cunna- 

 mara in the west of Ireland. In the same station we also found 

 Arenaria verna, a species which is very abundant near Edin- 

 burgh, but which I never before gathered on the west side of the 

 island.'' 



In the Botanic Garden at Birmingham a specimen of Erodium 

 Hymenodes was pointed out, said to have been picked from among 

 many others on the Flat Holmes in the Severn, and which the 

 intelligent curator, Mr. Cameron, said had all the appearance of 

 being a native specimen when brought to him. Mr. Cameron 

 also pointed out a variety of Sedum Telephiumy which he first 

 observed in considerable quantity on the Titterstone Clee Hill, 

 Shropshire, in 1839, at an elevation of 1400 feet, and had culti- 

 vated since 1840 without any alteration in its character except 

 increase of size. It is distinguished from the ordinary state by 

 its smaller fruit, its procumbent stems, and its long, slender, 

 horizontal, underground stoloniferous shoots. 



The plants which appeared characteristic of the neighbourhood 

 of Cheltenham, Bristol and Bath were — Viburnum Lantana, Cle- 

 matis Vitalba, Pastinaca sativa, and Convolvulus Sepium-, the 

 first three not belonging to the Flora of Scotland, and the last 

 remarkable for its vast profusion in almost every hedge. These 

 plants were observed along the whole route to Weymouth, and 

 in addition, between Dorchester and Weymouth were seen Cnicus 

 acaulis and Campanula glomerata ; the latter, however, very small, 

 or at most never acquiring the luxuriant appearance it has in 

 the neighbourhood of Edinburgh. A few plants of Carduus erio- 

 phorus were seen by the road- side a little way to the southward 

 of Bath. 



One of the most interesting walks of the whole excursion was 

 that of the 16th of August, along the beach parallel to the Chesil
