Normally the whip-like cord coming from inside the throat (spadix
appendage) is upright, but when the flower is past its prime, the cord
droops, as seen in the pictures here.
It should not be Arisaema intermedium because in that species the
"hood" (spathe) of the cobra-lily has a 2-3 cm long tail-like tip, as
can be seen in the following:
http://www.pacificbulbsociety.org/pbswiki/index.php/ArisaemaSpeciesThree
The "hood" of Arisaema tortuosum, on the other hand, is pointed, but
has no tail-like tip. To me, Ushaprabha's images appear to agree with
Arisaema tortuosum.

indeed trifoliate, it surely cannot be A. tortuosum.
Then, this could be a species not yet reported from Arunachal Pradesh.
We found Arisaema elephas in Tawang region, from where it is not
reported (as far as I know). So, one may have to look at some species
from China, the neighboring region.
One such candidate is Arisaema handelii, which has trifoliate
leaves,

Arisaema griffithii-group (notice the reticulated innerside of spathe
blade in the last picture) and the elephas alliance. AP is and area
where the Sino-Himalayan and Indo-Himalayan floras meet and there are
many plants that show characteristics of species from both areas. The
Arisaema griffithii group usually has long threadlike appendices and
not the thicker and short appendix of the plants on the pictures.
Similar but darker plants can be found in the Yumthang area of N
Sikkim where the slow change from griffithii type plants to this type
and further on to true Arisaema elephas is more apparant. Further east
in AP similar plants like this are found that have a more beige-orange
flowers.
Some remarks on names mentioned in this thread:
- Arisaema handelli is very similar to Arisaema elephas but has a
rather narrow distribution range in China, most important
characteristic of this species is a rugose (rough, like sandpaper)
appendix wheras the plants on the picture have a smooth appendix, it
also has a flowerstalk that generally is shorter than the leafstalks
whereas the plant on the pictures has its flowers as high or higher
than the leaves.
- Arisaema intermedium has a very long threadlike appendix that can
reach 50-70 cm in length, it is also much smaller with narrow, more
elliptic leaflets, not the broad rhombic leaflets of the AP plants
- Arisaema hookeri (or hookerianum) is the lowland form of Arisaema
griffithii that can be found at Tiger Hill and some parts of
Shingallila National Park in W Bengal. It differs from normal
griffithii by a very triangular folded spathe and a more purple
colour. Nevertheless it is a full synonym of Arisaema griffithii.
- Arisaema sivadasanii is a endemic autumn-flowering form of Arisaema
tortuosum from S India. It has now been reduced to a variety of
tortuosum by Punekar and Kumaran
Whether the plant on the pictures has characteristics sufficently
unique to warrant a separate status extensive fieldwork needs to show.
As it is it doesn't fall within any known species I would suggest to
ID it as Arisaema species aff. griffithii-group.

not seem to fall in any of the know species. Because of the appendix
shape it shows some resemblance with Arisaema elephas (which generally
is purple flowered) but particularly in the last picture the
reticulation on the inside of the spathe blade shows its close
affinity with members of the Arisaema griffithii group. Griffithii
normally has a thin, threadlike appendix but in some areas at higher
elevations the appendices seem to get shorter and thicker and slide
towards Arisaema elephas. This occurs for instance in the Yumthang
area of N Sikkim. Because of the present reticulation (nettled veins)
I would suggest to id it as Arisaema griffithii aff. Further field
research is needed to establish its true status and find out whether
it deserves a separate status. Because Arunachal Pradesh is in between
the Indo Himalayan and Sino Himalayan Flora many intermediate forms of
Arisaema have been found of Indian and Chinese species, for instance
intermediates between the sister species Arisaema galeatum (India) and
Arisaema dahaiense (China).
Some remarks on the proposed names in this thread:
- As noted Arisaema handelii has a rugose (rough, like sandpaper)
appendix and a rather restricted distribution range in China, the
plants on the pictures have a smooth appendix. A. handelii also has a
flower stalk shorter than the leaf stalks in contrast to the plants on
the pictures.
- Arisaema sivadasanii is a narrow endemic species from S India and is
recently reduced to a variety of Arisaema tortuosum, it does not occur
in N India and is usually autumn flowering, it belong to a different
section within the genus and has pedatisect leaves, not tripartite
- Arisaema hookeri ("hookerianum) is a full synonym of Arisaema
griffithii. It is the lowland form of griffithii from ~2000 m altitude
that occurs for instance at Tiger Hill in W Bengal, it is usually
reddish purple and of all the forms of griffithii has a spathe that is
the most turned back on itself pointing much backward and usually even
so recurved that it embrasses the flowering stalk.
Hope this helps,
