BOTANY 



Snout. The flaccid and dark-coloured Jungermania cordifolia may be 

 found by the waterfall at Burtree Ford, on the bank of Ireshope Burn, 

 and at the High Force. Jungermania Floerkii grows on the top of 

 Burnhope Seat, on Widdy Bank Fell, and on the top of the Weardale 

 road leading into Langdon Beck. Of this genus Jungermania barbata is 

 the characteristic species on the gravelly drift by Burnhope Burn, and 

 Jungermania bantriensis occurs in great abundance below Winch Bridge 

 in Teesdale. With Lepidozia setacea on Widdy Bank is associated 

 Jungermania porphyroleuca in fruit. Of the genus Eucalyx, one member, 

 obovata, has been noted above, and the other member, hyalina, grows on 

 the moorland by the side of Sedling Burn ; Nardia compressa occurs in 

 wet places by Burnhope Burn, in darkish masses. Pallavicinia Lyelli has 

 been recorded from the Durham side of the Tees (Spruce). Mixed 

 with the mosses Cinclidium stygium and Amblyodon dealbatus on the slope 

 of Widdy Bank grows the var. angustior of Aneura pinguis. The soft 

 hairy masses of Metzgeria pubescens grow on the vertical limestone 

 cliffs of Ireshope Burn and also at Cowshill. On the saccharoidal 

 limestone of Falcon Glints are large green flat patches of Chomiocarpon 

 quadratus. 



In Weardale a striking feature in the rills and ditches by the road- 

 sides, especially the Kilhope road, is the great abundance of the hepatic 

 Scapania undulata, whose masses almost choke up these waterways with 

 their glassy green-looking foliage.
