Looks like Ludisia discolor, which is a jewel orchid. Or is could be some other similar jewel orchid, I don't know this group very well. These are grown more for their foliage than their blooms, although those are nice as well.

I agree it is probably Ludisia discolor. Other jewel orchids are similar but usually have more distinct net-like markings on the leaves rather than these simpler stripes.
