Widdybank Tell is only 1716 feet in height, and of it 

 has been said, " there is probably no piece of ground in 

 Britain that produces so many rare plants within a limited 

 space as Widdybank Fell." 



We were fortunate enough to gather most of the rare 

 plants known to grow in this locality, although we missed 

 a few which grow very sparingly, and were not in flower 

 during our visit, such as A renaria nliginosa. In fact, we were 

 too late for most of the rare plants of Upper Teesdale, 

 After ascending to the top of the hill, we descended by a 

 small stream which leads into the " Weel," a peculiar tarn- 

 like expansion of the Tees, fully five miles in length, where 

 the river is deep and sluggish. In the Weel we gathered 

 Sparganium natans. At the foot of the Weel the Tees 

 forms a series of beautiful waterfalls, the highest of which 

 is called the Caldron Snout. Here a suspension bridge 

 crosses the river, from which a fine view of the w^aterfalls 

 is obtained. 



On the Durham side of the river, for two miles below the 

 Caldron Snout, the rocks are high, precipitous, and some- 

 what difiicult to explore. These rocks are called Falcon 

 Glints. Woodsia ilvensis is said to have been found on 

 these rocks, but is believed now to be extinct ; certain it 

 is we saw no trace of it. We found several good plants on 

 these rocks, such as Druha incana^ Thalictrum alpinum, 

 Arenaria verna, Saxifraga aizoides and hyp)noides, Sedum 

 Rhodiola and villosum, Epilobium angusti/oUum, Lonicera 

 Periclymenum, Galium sylvestre and horeale, Carduus heter- 

 ophyllus, Hieraciuni horeale^ Juniperus communis. Of 

 ferns we found Cryptogramme crispa, Asplenium Buta- 

 muraria, Tricliomanes, viride and Adicmtumnigrum, Poly- 

 jDodium Phegopteris and Dryopteris, and a fine plant of 

 Nephrodium Filix-mas var. yumila. On the way down 

 we found a few plants of Gentiana verna in fruit. 



On Wednesday, 30th July, our excursion was to 

 Cronkley Fell, a mountain on the Yorkshire side of the 

 Tees, and to the south of Widdybank Fell. It is 1739 feet 

 high. The rocks on the summit are composed of that
