Impatientes, and Eriocaulons. The grasses had become more withered, and
the general tint was brown. No kites (Falco milvus) are to be observed
out of Churra.

The plants which were particularly conspicuous about Churra, were past
flowering in the interior; thus Osbeckia Nepalensis? was not to be met
with in flower in the interior, while it is in profusion about the
station. The same may be said of other instances.

After all Churra presents the richest flora of any other place in the
Khasyah hills, because there is a greater extent of wood near it, than is
found in any other locality, much greater _altitudes_ and deeper descents
in its ravines, and it is as it were the transit point between a tropical
or sub-tropical, and a temperate vegetation. I have no doubt, that
within a circle of three miles of Churra, 3,000 species might be found in
one year.

The principal plants pointing out the tropical nature of the vegetation
are Pandanus, which is almost limited to the limestone formation, on
which it is excessively abundant, Chamaerops Martiana? which from its
affecting particularly the walls of the amphitheatres so conspicuous
about Moosmai, Mamloo and Surureem, and the depths of whose sides is
probably at Mamloo 1,000 feet, might have been better named. I have
never seen it on any other places. The Alsophila Brunoniana is likewise
apparently confined to the limestone hills, while the tree fern,
Polypodium, is found on sandstone, as well as Impatiens, Tradescantia,
Commelineae, Eriocauloneae, Xyres, almost all the grasses, Melastomaceae,
almost all the Leguminosae and the preponderance of tropical Rubiaceae,
which are, however, few, Scitamineae, Epiphytical Orchideae, Urena
Labiata, etc. etc.

On the _23rd_ I went to Mamloo, which is about four miles to the west of
Churra. To this place the limestone ridge, extending from Churra, nearly
approaches: its vegetation is not rich but always stunted: rocky
amphitheatres are very remarkable at Mamloo, they are of excessive depth;
their walls being generally perpendicular, often somewhat overhanging.
The manner of their formation is now to be seen in the amphitheatre
immediately contiguous to the village, although it appears to be very
slow. It is thus, bodies of water falling from the edge of the table
land, seem to undermine the sandstone below, producing land slips, which
occur in this manner year after year. Since 1835, the edge of the
Moosmai fall has receded
