It's a Pilea....not sure what species.

I'd suggest Pilea Norfolk - its get much more bronze if grown in sunlight, but more greenish without.

I used to grow loads of Pilea in the palm house in Brighton. The old memory ain't as good these days !!!!

Thank you, both! Any need to know growing instructions?

Nothing particularly startling - average warmth, min 50 deg F in winter, bright light or semi shade, protect from direct sun in summer, water liberally spring to autumn, allowing the compost to dry out in between, but not to the point where its shrunken from the pot, use tepid water, mist leaves regularly, repot in spring. That's what the Houseplant Book says...
