JOURNEY TOWARDS BOOTAN. 



pora and Polypodium Wallichii were found ; ascending a few feet, say 

 60, Randia microphyllum, Aneilema aspera, and pines appeared 

 in the woods, with straight trunks and high branches, occasioned by 

 the abortion of the lower branches, sometimes dichotomously forked, 

 bark grey, and scaley, branches horizontal, approximated ; cones in- 

 clining towards the axis. The descent occasioned a loss of pines, 

 oaks and chesnuts continuing, Orthopogon, Pederia triphyllum. 



This wood was of great extent, the path running along the pre- 

 cipitous or steep edge of a very wet water- course. Castanea ferruginea 

 very common, Cyrtandracea. 



Begonia malabarica, Achyranthes, Tradescantia flagellifera, Phlo- 

 gacanthus, Acanthacese, Sarcopyramis, Magnolia, Eupatorium arbo- 

 reum, Laurinese, Gleichenia minor. 



Pinus subsequently appears but is rare, Eurya. 



Daphne involucrata, Gaultheria arborescens, Knoxia cordata, Poly- 

 podium arborescens, Thibaudia, Viburni sp., Vareca,^ Leucas galea 

 brunacea. 



Then still gradually ascending, open woods occurred. 

 Pines, Q. castaneoides. 



Thence the ascent is still through open woods of pines. Cas- 

 tanea, Quercus castaneoides and callicarpifolia, Polygala here ap- 

 pears, Knoxia linearis, Flemingia, ^Eschynomene. 



On the top no Pines. Oaks, chesnuts, and Gordonise appear. 



Thence a second but small ascent, pines re-appear with birch, 

 Scutellaria, Erythrina, Melica latifolia, Epiphytes common, especially 

 on Gordoniae. The altitude of the summit before descending on 

 Nungtung was 3,359 feet : thermometer 75° . boiling point 206°.
