Wildflowers: Colombian Aroid?

Is this plant an aroid?

 

The plant reminds me of Piper spp.

 

That's Piper for me too. Which one I'm not immediately sure, though.

 

Thank you both. There's a lot of Piper umbellatum around but the above example is the only time I've seen this species.

 

Piper anduncum (Matico) is similar when young.
