Need help to ID new plants

[theodore]

Just bought some plants today but I'm having some trouble ID-ing two of them (see pic : New Plants).

The bunch on the left looks like Eriocalon setaceum but the leaves seem shorter than what I see in the Oriental book. Could the bunch on the right be Eichhornia diversifolia?

Thanks!

right is the Eriocaulaceae sp., the left one can't really tell the different Eriocaulon sp.
