Here are a variety of aroids growing in the woods around my house. I know various details are required to propery identyfy them but if the identity of any stand out please comment.
First two: Xanthosoma sp.
Third: Anthurium sp.
Fourth: Philodendron sp.
Fifth thru Ninth: Anthurium species (several different ones)
The Anthuriums are so variable and not my specialty so I cannot key them to species. The Xanthosoma may be sagittifolium but could be another closely related species. The Philodendron is similar to several species so without an inflorescence in detail, keying that one would be difficult at best.
4th pic is Philo pastazanum
