En route thither, Pholidota imbricata, Thib. loranthiflora, Aralia terebinthacea, Rottleria foliis peltatis, Ranunculus of Taseeling, Meniscum majus, Byttneria ferox, Caladium foliis medio discoloratis saepius atratis, Gnetum, Ixora, Choulmoogra, Phlogacanthi sp., Corisanthes of Sudya, Acer platanifolia, Croton foliis oblongis irregularis dentato-lobatis occurred before, between 2,500 to 3,500 feet, Calamus, wild plantains as before, Gordonia, Rhus, Mimosa, Rottleria, Wallichia, Sida cuneata, Tradescantia cordata, AEschynanthus fulgens, et altera, Tupistra, Lobelia baccifera, Costus, tree-fern, as high as 5,000 feet, Bambusa fasciculata; of birds, the large Bucco.

At 5,000 feet, Thibaudia serrata, and on this side, as low as 2,500 feet, myrtifolia, Gordonia, Pythonium majus and medium, cinnamon, Piper, Acer platanifolia, Mucuna, Angiopteris, Saurauja ferruginea.

At 5,300 feet, Polygonia pinnatifolia, Hookeria macrophylla, Aralia scandens, etc. as before.

On descent nothing remarkable, except steepness:  same vegetation.  Pythonium majus not below 3,000 feet, Guttiferae at 3,000 feet, Acanthaceae, Carduaceus 2,800 feet.

At 2,500 feet, Buchanania undulata, Hyalostemma undulatum, Roydsia.

What can be the cause of this tropical elevation at such altitudes?  Buxa is hot enough for any tropical plants, as jacks, mangoes, Cactus, etc. are found in fine order.  It is not attributable to a gradual rise, as the ascent from this to 5,500 feet, is excessively steep.  It must be owing to local causes modifying the climate:  at 5,000 feet on the Dgin route, there are many elevational plants, indeed more than of subtropical.

It must not be forgotten that no Pinus longifolia exists on this route after leaving Telagoung.

Buxa is a rather pretty place, but as usual poor:  the Doompa’s house is the only decent one in the place, the others, amounting to eight or ten, are common huts.  The big house occupies an elevation in the centre of the pass, being cut off from the neighbouring hill on either side by a ravine, one of which is now quite dry, the other affords a scanty supply of water.  The hills are covered with jungle, the only clearing being about Buxa, and this, except the flat summit of the hill, is overrun with bushes, Capparis modecea, Croton malvaefolia, Menisperma tropaeolifolia.  Bergerae 2 species, Ixora, Brucea same as of the plains, Atriplex, Tournefortia of plains, Maesa macrophylla, Mimosa scandens, Ficus elastica in good order, jacks, mangoes, oranges, plantains, Tabernamontana, Calamus, Cedrela Toona, are found.

Black pheasants, Bulbuls, Drongoles, Oorooa, Bucco, green pigeons.  Long-tailed blue-crested shrike, etc. are found here.  The Doompa, or Chong Soobah, is a man of no rank, and the place itself is of no importance, except as the pass or entrance between the mountains of Bootan and the plains of Bengal.
