two Bambusae in flower, and two species of
Meniscium, and a _Polypodium venulis_ tertiariis simplicibus. A
_Sarcopyramis Sonerilae_ was also found, but rather past flowering, and
an Acrostichum? or Lomaria? We did not observe any ravinules or hollows,
although mounds were by no means uncommon.

_Jan_. _18th_.--We proceeded in a Southerly direction, and after marching
for nearly seven hours arrived at, and encamped on, a largish plain, on
which paddy had been extensively cultivated. The whole route lay through
a vast and deep jungle, the road running partly on the side of an old
bund: part of our road was through very wet ground, part through rather
dry elevated woods, bamboos of two species occurred abundantly. We saw
several vast specimens of Dipterocarpus, one which had been cut down
measured from the base to first branch 110 feet. Ferns still continue in
excess. I gathered another species of _Sarcopyramis_; a _Goodyera_,
_Chrysobaphus Roxburghii_ in flower, but rare; and an Apostasia not in
flower.

_Jan 19th_.--We reached Negrigam early in the forenoon although we did
not leave our ground before 10 A.M. The road to the village was pretty
good. Negrigam is a largish village on the north bank of the Booree
Dihing, which is here a considerable though not deep stream. This bank
is at the site of the village very high. The population seemed to be
considerable. To the south, large ranges of hills were visible, the
first of which were close enough to admit of one's distinguishing them to
be wooded to the top. The inner ranges were lofty. We had some
difficulty in ascertaining where the tea was located, the accounts being
rather contradictory. At length we proceeded up the bed of a small
river, Maumoo, which runs into the Booree Dihing close to the village:
after wading along in the waters for two hours we arrived at a khet where
we encamped. The direction being from Negrigam N.W. along the banks of
this stream. The Pavia I first observed at Silam Mookh, was abundant,
and some of the specimens were very fine, the largest was a handsome,
very shady tree, of perhaps thirty feet high. The only plant of interest
was _Gnetum scandens_. On a high land bank I gathered a species of
Polytrichum, and one of Bartramia.

_January 20th_.--This morning we crossed the small streamlet Maumoo,
ascended its rather high bank, and within a few yards from it came upon
the tea: which as we advanced farther into the jungle inc
