ton, I gathered what I take for Barbarea arcuata. It seems to me far 

 less satisfactorily distinct from B. vulgaris than B. stricta, which is so 

 common about York and in other parts of Yorkshire, and which I first 

 noticed by the side of the railway near Rotherham, and in many pla- 

 ces going thence to Halifax, late in May, 1842. 



Obligingly guided by Mr. Arthur Trevellyan, I visited the one plant 

 of Linnaea borealis discovered many years ago by Miss Trevellyan, at 

 Catcherside, some four miles from Wallington Hall. It is a wide 

 patch, in a plantation of Scotch firs, said to have been brought, about 

 eighty years ago, from Norway. Pyrola minor grows with it; and 

 Sedura villosum on the neighbouring moor. 



I regretted want of time to visit the pool in which Mr. Winch dis- 

 covered his Nuphar pumila. Mr. Trevellyan pointed out the direc- 

 tion in which it lies, some miles over the moor from Catcherside, and 

 showed me the plant in a pond at Wallington, to which it had been 

 brought. I have had it long in my own garden, from a plant origi- 

 nally sent from Northumberland (by Mr. Winch, I believe) to the 

 Oxford Botanic Garden. It is not the true N. pumila. I have re- 

 garded it as a small variety of N. lutea, but it deserves further atten- 

 tion. It may possibly be N. tenella, of which Reichenbach gives a 

 character under N. sericea, in his 'Plantae Criticae' (cent. 2, p. 10) and 

 ' Flora Excursoria ' (p. 14). 



I regretted still more that I had not time to go to Wall Town for 

 Allium Schoenoprasum. Mr. Thompson has some idea that there are 

 two species in that neighbourhood, confounded under this name.' 

 Some living plants that he has kindly sent me, have the upright habit 

 of the chives of our gardens, but the leaves are rough as in A. sibi- 

 ricum. 



If I had not the satisfaction of verifying Mr. Wright's discoveries, 

 I had no better success in hunting for Hudson's lost plants, his Saxi- 

 fraga csespitosa, Hieracium dubium and H. Auricula. For want of 

 time and fine weather I did not ascend Loughrigg Fell, nor Wansfell ; 

 but I left scarcely any other mountain " above Ambleside " unvisited. 

 A thorough investigation of those mountains, however, would require 

 weeks, or months, and Hudson's plants, and many a plant as yet un- 

 observed besides, may perhaps reward the industry of future visitants. 

 I flattered myself that I had got a clew to the Saxifrage, when I ob- 

 served S. hirta on a rock in the chapel-yard at Rydal, and was shown 

 the same on a planted rock in the gaiden at Rydal Hall, by the cha- 

 pel-clerk, George Bankes, who is also gardener to Mrs. Arnold, at 

 Fox How, and assured by him that it had been planted in both places
