My guess is that it's one of the plain green forms of Chirita sinensis. A picture of a fully opened flower would help. Also, I have to wonder if the foliage is really as blue as it appears in the photo.
Thank you! I trade with other people, order by mail, grow from seed, buy leaves or stolons. I also joined a couple of african violet societies where I sometimes can buy gesneriads too. If there is no gesneriad society in your area you can probably find an AV society and these people are generally interested in gessies too.
