[jimbooo]

it's the big rosette plant in the centre (wide green leaves)

not sure what it is but it's roots reach from one end of the gravel to the other.

Definitely Echinodorus species, not sure which variety though - possibly Echinodorus schlueteri. Nice plant whatever it is.

Looks a little like my e. macrophyllus, but maybe a little different...
