Typhonium. ??

Yes, it is Typhonium Sp.

Not Typhonium but the related genus Theriophonum, this looks to be Theriophonum infaustum.

It is Theriophonum, but the flower height is bigger than flower of my plant. Maximum length of my flower is 05cm (five centimeters) or less.

That is the normal size of the spathes of Theriophonum infaustum. When you look at the page for this species on the International Aroid Society you will see pictures of plants grown from a collection I originally made of this species in the Idukki District. One of the pictures you will see part of a finger for size reference. But I want to stress as always if people want ID’s of an Araceae, cut the spathes open and picture the internal organs as those are the most important for identification.

Yes, it is Theriophonum infaustum. …, my plant is growing in the border of Idukki district in 70% Idukki’s climate.  Thank you very much for ID my plant and sharing more information about this
