OK smarty plants. Now if you start spitting out this ones name I will not only be impressed but suprized. This one has fulled botanist for years and is finally getting cleared up but still a bit messy with the species so I will be happy with just the family name. But the bonus is the exact name species name.

Here are the clues
South american species
At first glance one would call it a palm species botanist put it in the araceae or aroid family. Later it was put into the same group as pandanus. This is a picture of it flowering
if I get no good guesses I will send a pic of the plant
