It's the other way around: the treant brought a tahina over, then MC thought about its properties. The tree is right there being carried 3 pages prior.
I can agree that the grammar makes it sound like the tahina isn't already right in front of her though, maybe TL didn't notice that the treant was carrying it earlier either? No biggie, it's a minor detail, easy to miss. I had to go back to check where that palm came from after she ate one too.
