The first one is definitely the plant called Hygrophila sp. 'Araguia'. The second? I'm not sure what Hygrophila it is. It's not an impossibility that they're both called 'Araguia' and could be from the same general area. It really underscores the fact that these trade names - if that's what we can call them - are merely place holders until we figure out what they really are. I wish I could be more helpful in the meantime.
