Even in these there is no comparison in luxuriance and variety of vegetation with the Mishmee or Bootan portions of the same stupendous chain.

The trees are few in number as regards species, the only ones I have observed are a species of oak which is very common, forming the chief vegetation of the northern faces, and of both those of Mount Jacka.

The scarlet Rhododendron which occurs in the highest parts of the woods, an occasional Pyrus, Benthamia, Euonymus, Gaultheria very common, also Pinus Deodara, longifolia, and excelsa; of these the Deodar is most common.  Ilex, a pretty tree, occurring on Mount Jacka.

The following forms also I have noticed—­Saxifraga ciliata, Berberis asiatica, and Gnaphalia three or four species, which are chiefly confined to grassy naked ridges.  Thymus is also confined to these.

Ruta albiflora is very common in woods; Dipsacea and Artemisia on exposed grassy spots; Swertia is common in damp places; Spiraea bella, Ledum, Stemodia, Epilobium, Viola, Saccharum rubrum, Valeriana, Fragaria, Galium, Clematis, Rosa, Rubus, Rumex, Leguminosae, Coronilloid, Smilax.

Acanthaceae, Androsaceae, particularly a Gnaphalioides common on the exposed ridge of Mount Jacka; Myrsinea frutex, Parnassia common, Salix fruticosa; on Prospect Point, Lycopodium, Herminioid, Epipactis, Orchideae aliae, 2 Scitamineae.

Elaeagnus, Mespilus microphyllus, Polygonum of Chugur; 2 or 3 Amaranthaceae; Prinsepia, rare; very little variety in ferns; Pteris chrysocarpa, Aspidium pungens, and another are the most common; nor is there any variety in Epiphytous ferns, and very few Jungermannias.  The Mosses are Bartramia, Catharinea, Polytrichum aloides on banks with Fissidens, otherwise Hypna are the most prevalent.  A Neckera hangs from every tree, and a Pterogonio Neckeroid covers almost every trunk, a Brachymenium is likewise common.

Altogether, though numerous, there is no great variety in form.

On the summit of Chaka, Quercus, Gaultheria, and Rhododendron are common; with here and there a Deodar.

On the east face of that mountain consisting of a long ridge, grasses form the chief vegetation, among which Andropogons and Schoenanthus are not uncommon, Gnaphalia and Artemisia occur; Thymus, Androsace gnaphalioides, Potentilla, Coronilloid, Labiata frutex, Jasminum, Rosa, Mespilus microphyllus, Clematis, Cnicus, Rubus, Labiata alia, Galium, Swertia, Salvia were noticed.

Of the tropical forms, Andropogoneous grasses are most common, Saccharum rubrum of the Khasyah Mountains, Desmodium, Acanthaceae, and Elaeagnus, which last occurs on Prospect Point.

Saccharum rubrum extends up to 8,000 feet.

The woods generally on the surface are matted down with grasses or Carexes, so that there is no variety of surface for the lower orders; in such places, Ophiopogon is very common.

Regarding the Coniferae, Pinus excelsa is the rarest, Deodar is the most common; longifolia occurs principally on a southern projection from Chaka, and on the south face of the Mall ridge.
