A beautifully marked Melastome with broad silvery white leaves.  It’s fairly easy to keep alive but in my experience is very slow to grow or propagate.  I suspect it would grow faster from seed and recommend trying to collect seed if you want to share it.  It is native to Brazil and grows a very nice compact rosette to about 8″ wide.

The last photo is representative of the plants available. They are in 4″ pots.
