In two gardens at Keswick I saw this beautiful plant, thriving and in 

 full flower, early in June. The roots were supposed to have been 

 brought from a wood in Legberthwaite ; but understanding the spe- 

 cies to be now lost there, and having seen it in Yorkshire and ga- 

 thered it in Durham, I did not visit the locality. I subsequently 

 searched a reported station in Fairfield, among debris of rocks, be- 

 tween Rydal-head and the Dove Crag, but, I acknowledge, without 

 expectation of finding it. 



In Teesdale, August, 1845, I had the pleasure of seeing Hieracium 

 Lapeyrousii [Bab.), and the other species named by Mr. Gibson, and 

 H. inuloides in addition, but sought in vain for Arenaria uliginosa, 

 although the younger Mr. Backhouse, the actual discoverer, I believe, 

 had kindly given me a most accurate direction to the station. It is 

 said that the place was visited by another collector subsequently to 

 the discovery, and I fear the plant may have been extirpated. Yet, 

 surely, it may be expected to re-appear. Arenaria verna abounds 

 there. Juncus triglumis grows by the stream in one place ; and some 

 of the good Teesdale plants, Gentiana verna, Kobresia caricina, Carex 

 capillaris, are in plenty near at hand. 



Poa Parnellii occurs at Caldron Snout, and at the confluence of 

 the Greta, the highest and the lowest points that I visited of the course 

 of the Tees, and in various places between. 



Rmnex aquaticus seems common in Teesdale. In some wet mea- 

 dows it is a troublesome weed. 



Guided by "Kit Dent" of Cotherstone, early in June, 1842, I vi- 

 sited the spot by Balderdale where he had long before discovered 

 Saxifraga Hirculus. It is in some boggy rills in the Cotherstone 

 Fells, which, uniting, form a little gully, and fall, after a very short 

 course, into the Balder, a mile or two above the highest farm-house 

 by the valley, and perhaps about the same distance below the other 

 station by the junction of the Black Beck. The place is well marked 

 by a solitary old mountain ash, the only tree in the neighbourhood, a 

 very little way above the gully, and on the opposite side of the river. 

 The plant was not in flower, of course. I did not go to the Black 

 Beck. 



I am glad to learn that Woodsia ilvensis still exists at the Falcon 

 Glints. I saw it there in 1842. I have not visited the spot since. 



I could not find Equisetum umbrosum at Winch Bridge. E. vari- 

 egatum was there, and the common E. arvense. 



Epilohium virgatum grows near Barnard Castle, by the road to 

 Greta Bridge, and by the Gormire Pool near Thirsk. By this pool a
