The formation of the stigma decidedly indicates a binary formation of carpella.

If these 4 upper cells are 4 constantly, and the base of the ovary is as constantly two celled, then the explanation is sufficiently obvious, though different from that given by Lindley. {113}

First, we have in the bottom from which the mere structure of an ovary is deduced, the normal dicarpellary structure, and there is in addition a tendency in excess toward a parietal placentation.

The anomalous formation arises first from parietal placentae being produced to the axis, and from spurious growth from the sides of the ovary also meeting in the axis, by which the ovula are divided into four bundles.

Lindley's view seems to be questionable, because as in all cases the styles and stigmata are more permanent than ovaries, there should be as many styles, etc. as ovaries. 2nd, because according to this view the placental suture of the carpella would be turned from the axis, (look at Pomaceae,) although his view of Pomaceae being right would indicate an additional affinity with Mespilus, etc. which it does in habit and abbreviated lateral branches.

Are all Myrtaceae dicarpellar?

The true nature of the case is pointed out in the instance cited by Lindley of a permanent variety of apple, which has 14 cells and 14 styles! With regard to Nicotiana and Nolana; have these one or two rows of carpella?

The fruit of Lagerstramia grandiflora can, I think, be explained by a.s.suming it to consist of several carpella, which by not becoming united near the axis, leave an irregular shaped s.p.a.ce in the centre; the placentae are fleshy, the ovule inserted all around. This view does not take into consideration the situation of the stigmata. The deeper sulci visible externally correspond to the inflexions of the carpellary leaves; in addition to this, the centre of the dorsum of each of these is marked with a line. {114})

CHAPTER VII.

_Report to the Government of India_, _12th July_, _1837_.

In the following report, I have divided the marches into series, corresponding with the countries through which they were made, reserving a table of the whole for a subsequent part. These series will be as follows--

1. From Sadiya to Beesa Lacoom.

2. From Beesa Lacoom to Namtusseek.

3. From Namtuseek to Wullabhoom.

4. From Wullabhoom to Mogoung.

5. From Mogoung to Ava.

I. FROM SADIYA TO BEESA LACOOM.

COUNTRY TRAVERSED BELONGING TO THE BRITISH GOVERNMENT, AND FORMING PART OF THE SOUTH-EAST EXTREMITY OF THE VALLEY OF a.s.sAM.

1. From Sadiya to the Noa Dihing river mouth or Mookh. Direction east.

Distance 6 miles performed in boat, the course lying up the Burrumpootur.

2. From Noa Dihing Mookh to Rangagurrah on the Noa Dihing. Direction SSE. Distance 12 miles, course lying along the dry bed of the Noa Dihing.

3. From Rangagurrah to Moodoa Mookh, on the same river. Direction south- east, the distance being 12 miles. {115a}

4. From Moodoa Mookh to Kidding. Direction south, the distance 9 miles, course south-east, along the bed of the Noa Dihing as far as Wakhet, thence diverging to SSW. through heavy jungle.

5. From Kidding to Namroop Puthar. Direction, nearly south, the distance being 12 miles, course lying through very heavy jungle, crosses the Karam Panee, {115b} which here is not fordable, and another considerable feeder of the Booree Dihing, and lastly up the Namroop.

6. From Namroop Puthar to Beesa Lacoom. Direction southwest, the distance 12 miles, the course extending at first over low hills and difficult ground, thence through heavy jungle intersected by narrow plains, lastly chiefly along the banks of the Darap Panee.

_Nature of the country_.--It will be seen that with the exception of the three first marches, and part of the fourth, the country is occupied by the heavy jungle so prevalent in these parts. The chief difficulties our party experienced arose from the limited manner in which the jungle had been cut for their pa.s.sage.

_Rivers_.--The only one not fordable in the above route, is the Karam Panee, but this does not hold good either above or below the place I crossed. They all discharge much water during the rains, and even in the dry season are navigable for small canoes.

_Villages_.--These are as follows:--

1. _Digalo Gohain Goung_.--On the right bank of the Noa Dihing it is inhabited by Kamptees lately settled in our territory, and is a respectable village. The Noa Dihing here ceases to be navigable even for small canoes.

2. _Wakhet_.--This is a new but wretched village, inhabited by Singphos.
