284 YORKSHIRE NATURALISTS IN UPPER TEESDALE. 



Upper Teesdale for the three days' excursion, and to those who 

 availed themselves of the opportunity a rich treat was in store. As 

 to records, some little difficulty was experienced owing to the routes 

 embracing portions of three counties, but by a careful sifting of notes 

 they had been able to make a reliable list of the plants on the 

 Yorkshire side of the river. As a result of close work and careful 

 observation, 311 species and 6 varieties were recorded. Unfor- 

 tunately, the grasses and sedges were almost entirely neglected, or 

 the number might have been considerably augmented. Beginning at 

 the lower end of the valley, the first plants of note were met with in 

 Park End Wood, viz.: — Melampyrum sylvaticum, Paris quadrifolia 

 (mostly with five or six leaves), and Geranium sylvaticum. The 

 rocks about Fairy Dell and Holwick Scars gave the typical ferns 

 and club-mosses, the chief being Cryptogramme crispa, Asplenium 

 rula-muraria, tricliomanes, and viride (the latter being the more 

 common form), Cystopteris fragilis, Polypodium phegopteris and 

 dryopteris, Lycopodium selago and davatum and Selaginella selaginoides. 

 It was on touching the river at Winch Bridge that some of the best 

 plants made their appearance ; here everyone was delighted with the 

 pretty golden flowers of Potentilla fruticosa, now seen at its best and 

 forming one of the most striking botanical features of the valley ; 

 good things were met with on every hand, and on following up the 

 stream to High Force were seen Pyrus aria, Galium boreale and 

 sylvestre, Solidago virga-aurea var. cambrica, Gnaphalium supinum, 

 Carduus heterophyllus, Serralula tinctoria var. monticola, Primula 

 farinosa, Polygonum viviparum, Equisetum pratense and variegatum. 

 Several good Hieracia were found and of those determined were 

 iricum, pallidum, and tride7itatum. Still further up the valley 

 towards White Force, Cronkley Scars, and Maize Beck were Viola 

 lutea var. amcena (which seemed to replace the yellow form), 

 Saxifraga aizoides, stellaris and leaves of hypnoides, Sedum villosum, 

 Listera cordata and Habenaria albida. One party, unaware of the 

 promise to confine themselves to the valley, journeyed by way of 

 Mickle Fell, Cronkley Fell, and White Force. They were thus 

 brought into contact with the noted sugar limestone, and their 

 innocence was rewarded by many good finds, including Draba 

 incana, Helianthemum canum, Alsine verna, Rubus chamczmorus, 

 Dry as octopetala, Saxifraga hir cuius, Epilobiutn alsinifoliufn, Pyrola 

 secunda, Tofieldia palustris, and Lycopodhc7n alpinum. 



Mr. J. A. Wheldon, of York, has since supplemented this report 

 by furnishing the following list of Hieracia which he collected and 

 have been determined for him by Mr. Hanbury : — H. angustufn Lind.
