I found this one in the deep shade in dense forest vegetation. It called attention with its paleness. My first thought was some kind of Arisaema, but Brazil has none recorded of this genus.
So maybe it is a close relative?
I missed it in bloom, but it had a seed pod. There was only one single leaf on a thin stalk of about 50cm tall.
Not sure if the paleness is a natural variegation of the species..
