BOOTAN. 



The ascent was through precisely similar vegetation, in one place 

 it was exceedingly pretty, consisting of sward with pines. Here 

 snow was lying on the ground in sheltered places to the depth of 

 several inches. The ground hence was levelish, but between this 

 place and the summit a rise of a hundred feet took place. Between 

 these places Abies densa, cedroides and spinulosa, occurred, but this 

 was uncommon, Rosa ramis hispidis, Salix of yesterday, Bambusa 

 of Sanah, stunted Pteris aquilina, Betuloidea, Hydrangea, Hypnum 

 rufescens, scolopendrioid as well as below : Spirsea belloides, Rhodo- 

 dendron obovatum, which varies on the same plant with ferruginous 

 and white leaves, Sphagnum, Thibaudia orbicularis. On sward Gen- 

 tiana minima. 



As the snow increased, Abies cedroides became less, Abies densa 

 more common. At the very summit Parnassia, Polygonum rheum, 

 Composita penduliflora, Rhododendron hispidum, Berberis spathulata, 

 which had occurred previously, Vaccinium pumilium, ciliatum, Gen- 

 tiana minima, Swertia, Cnicus, Compositae frequent, Labiata spicata 

 of Dhonglaila. 



The descent was at first open, through swardy places : here Acer 

 sterculiaceum, Geranium scandens, Avena, Abies densa, Juniperus 

 fruticosa, raro arbuscula. 



At 9,800 feet, Rhododendron foliis lanceolato-oblongis subtus 

 ferruginea tomentosis, arborea, became very common, forming large 

 woods, Abies densa interspersed, Juniperus, Betuloidea which has six 

 or seven layers of bark, the boj-putah of Hindoostan according to 

 Blake, Rosa microphylla, Hemiphragma, Daphne papyracea, Dicra-

At 9,500 feet, Clematis, Berberis asiatica, commences, Betula, 

 common Andropogoneous grasses. 



At 9,300 feet, Primula pulcherrima, Abies cedroides very common, 

 Abies densa ceasing, Buddlsea purpurescens, Aruncus, Bupleurum. 



At 9,200 feet, Lonicera villosa, Vaccinium cyaneum, Bambusa 

 alia, Abies densa ceasing. 



At 9,000 feet, the jungle now became humid, Gaultheria flexuosa, 

 Mespilus microphyllus, Quercus ilecifolia, Tetrantheroides baccis 

 nigris, Gaultherium nummularifolia common, Rubia cordifolia ! Hy- 

 drangea. 



At 8,900 feet, Junipers ceases, woods of Q. ilecifolia and Pinus 

 cedroides, Rosa microphylla, shrubby Rhododendrons, that which 

 was arboreous previously now becoming shrubby, Berberis asiatica,
