Flowers of the Eastern Ghats- Cobra lily

 The Cobra lily, Arisaema is endemic to the Eastern Ghats- a low hill range parallel to the eastern coast line of India.

While Arisaema tortuosa is found in the rain forests of the Western Ghats, this Arisaema is found in the Kolli Hills of the Eastern Ghats.
The remarkable thing about these plants is that they are hermaphroditic. They start life as male plants, and when they are mature, they turn into female plants.
I would be grateful for a correct identification of this Arisaema.
