Are you sure this is the plant that was said to be Primula fransisca Arif?

This looks like a woody plant, how big does it grow and is it deciduous? The habit reminds me so much of Iochroma so it could be in the same family.
In fact it reminds me a lot of Browallia, B. speciosa is very similar but not as far as I know a woody plant.

Brunfelsia pauciflora comes close!
