DESCENDS FROM 5000 TO 3000 FEET.

Gymnostomum involutum, Berberis pinnata, the same as the Khasiya 

 one, but scarce. Laurinea arborea, Bambusa monogynia, Rubus 

 moluccanus : Frutex Ruscordeus, Loranthus, Anthistiria arundi- 

 nacea, Melastoma, Cyathea, Composite, Conyzoideae two or three, 

 Correas one, Hedychium, Eurya, Gleichenia, Hermannia, Lycopodium 

 ceranium, Hoya teretifolia, Acanthacese two or three, Bucklandia. 



We thence descended, and after a longish march reached the 

 Natkaw Kyown, and finally halted on the Khusse Kyown. During 

 this portion I gathered some very interesting plants, a new Ceratos- 

 temma, Adamia, two or three Orchidese, a beautiful large flowered 

 Cyrtandracea, the same Daphne, an Umbellifera. Vaccineacese, four 

 species of Begonise, a Viburnum. Crawfurdia and Polypodium Walli- 

 chianum, which roofed in our shed ; Musci increased as well as Suc- 

 culent Urticese in shady places. Smilacinae were common, especially 

 one at elevations of from 3 to 5000 feet inflorescentia cernua. The 

 features are the same, the drier woods crowning the ridges. On 

 the trees of these, Orchidese and Filices are common, as well as in 

 low parts in which Acanthacese abound. I saw no Betee-bhans 

 nor Deo-bhans, (peculiar bamboos). Of the above, Ceratostemma, 

 Daphane, Smilacinse, Cyathea, some of the Begonise, the large 

 flowered Cyrtandracese, Umbelliferae are sure indications of con- 

 siderable elevation. The course was nearly south. Distance about 

 13 miles. Thermometer in boiling water 206.° Temperature of the 

 air 50|°. Halting place, 3516. 



March 16th. — Started before breakfast, and reached the Khusee 

 Kyoung without any material descent. Thence we continued de- 

 scending on the whole considerably until we reached Namthuga, at 

 10 a.m. Thence the descent increased. Halted on Kullack Boom. 

 General direction S. ; distance 13 miles. Noticed Areca up to 3800 

 feet, as well as Cheilosandra obovata, Bletea melleodora, and Begonia 

 palmata as high as 3000 feet. 



At Namthuga a Sambucus, probably S. Ebulus, a Mimosa, Pothos 

 decursiva, Hedychium, Urtica urens, Gleichenia major, Tradescanthia 

 panicularis. Between this and Kullack Boom Acanthacese are the most 

 common ; Psederia triphylla appears near the Boom, together with 

 Arum viviparum. Black Pheasants were likewise heard on our route. 

 On the open halting place, grasses preponderate. Anthestiria arundi- 

 nacea, arbusculous Gordonia, and Saurauja, a Laurinea, Styrax, etc. 

 iEsculus asamicus is common, and profusely in flower, and Pteris as on 

 Thuma-thaya; Musaglauca made its appearance. From this open space
