 of Surureem, Gaultheria nummularifolia, Rhododendron viscosum. 



At 9,300 feet, Abies spinulosa becomes more common, Rosa hispida 

 and microphylla ! Pinus cedroides commences, Dalibarda, Daphne 

 papyracea, Thymus, Gnaphalia, Mespilus and Berberis, as before, 

 Potentilla. 



At 9,500 feet, snow lying on the path in sheltered places, Euphor- 

 bia, Gaultheria arboreoides, Hypnum rubescens, scolopendrioids, 

 Pteris aquilina, Melianthus, Rosa, frutex erectus ramis hispidissimis, 

 ramulis subglabratis, fructibus pendulis glabris, tubo-ovato, sepalis 

 lanceolatis. Salix arbuscula, gemmis rubur glabris, foliis lanceolatis 

 subtus glaucis, amentis faeminies pendulis, Bupleurum, Hydrangea, 

 Spiraea densa belloides ! Prunella, Pinus cedroides common at Poten- 

 tilla. 



At 9,700, 9,800, to 10,000 feet, Abies densa, a few trees, as usual 

 many blasted, from lightning confined entirely towards the summit, 

 Acer stercuilacea, Aruncus, Thibaudia orbicularis, A. spinulosa very 

 common*, A. pendula ceases, or at most only stunted plants occur, 

 Mespilus microphyllus, Berberis spathulata, Baptisia, these were very 

 common on west face, which is level enough and open. 



Here also Pedicularis, Bupleurum, stunted Pteris aquilina, Polygo- 

 num, Rheum ! Avena ! Pendulous lichens luxuriant. Along the level 

 tracts, the woods consisted entirely of Abies spinulosa, a minute Gen- 

 tiana common on the sward. 



The descent was steep to the ravine ; half-way down A. pendula 

 commenced to nourish, and towards the ravine it was more common 

 than A. spinulosa, Rhododendron microphyllum was seen on this 

 face at 9,500 feet, Verbascum at 9,200 feet, but most of the plants 

 seen on the east face were not found on this. Acer sterculiacea, 

 however occurred at 9,800 feet, otherwise pines were the most 

 prominent feature. 



At the nullah, Dipsacus, Elaeagnus, Salix lanata, Artemisia major, 

 Daphne papyracea, Rhododendron viscosum, Mespilus microphyllus, 

 Rosa hispida, spinus acutissimis, Bambusa of Sanah, Plectranthus 

 a large suffruticose annual species, common in all the same altitudes, 

 were observed. The subsequent descent was through woods of A. 

 pendula, with a few of A. spinulosa intermixed. 



The limits of A. densa, A. spinulosa and A. pendula, Melianthus, 

 Acer sterculiacea, Thibaudia orbicularis, A. cedroides, Rosa micro- 

 phylla, Pedicularis, Hydrangea, Baptisia, Berberis spathulata were
