I think it is Calathea bella
and it needs high humidity

Saleh,
I believe you're right, I looked up Calathea bella and the pictures look just like mine. Thanks! With respect to humidity, would a tray filled with water and rocks placed underneath the plant be sufficient?

That is a pretty C. bella

A pebble-tray will help with the humidity some,..yes.

Of course whenever I can manage to get my hands on such things like terrariums and wardian cases,plants that lust for humidity are very happy in them and it shows.

Meanwhile the pebble-tray will do. :)

I have 2 that look like this. One is very short and grows almost like a ground cover. The other is much taller. Whenever I buy Calatheas that's all there ever is on the label - "Calathea" and never a species or even variety. But they still look good whatever the name.

Tropic,
I agree with "they still look good whatever the name." :)

As far as the humidity question goes I move mine to the bathroom every now and then. For two or three days. Does just fine.
