Can someone please help me identify this house plant? It's lived in cups and water for six years and I love it!

It's a rather sickly looking Sansevieria 'hahnii' -image of how its supposed to look here http://www.glasshouseworks.com/sansevieria-trifasciata-hahnii. Click on image 2 because I think that's the coloration yours has, although it's hard to tell because yours isn't showing much striation or variegation.
Its quite a feat to get this to survive in water all those years, but it would be so much healthier if you potted it up into potting soil in a pot with a drainage hole, one that's big enough to accommodate the roots, preferably without cramping them up too much.
It is a compact variation of the 'average' snake plant: Sansevieria trifasciata 'Hahnii' (bird's nest snake plant).
You can find a lot of information about this plant here.
