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the page for this species on the International Aroid Society you will see pictures of plants grown from a collection I originally made of this species in the Idukki District.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

I would like the ID for the following two plants belonging to Araceae. One appears to be an Amorphophallus species and I am not sure of the other. Provenance is Palakkad, Kerala.


Theriophonum minutum


Thanks, …, On going through species in Flora of Peninsular India, I find it different from Theriophonum minutum as per details herein.
It appears close to Theriophonum infaustum as per details herein and as per
