From the appearance of the spathe, the species should belong to that of the C. cordata family but I am not sure which variety it belonged to. Below are the close up photographs of the spathe for your review. Note that the specimen had raised collar at the throat of the spathe.
The kettle was cut open and as usual, a fly "hopped" out in a daze after being unlawfully detained inside the kettle for some time.
So what do you think? Is this C. cordata var. cordata or should this be considered as . cordata var grabowskii?
