(I'll post this on the regular 'wanted' site too.)
If anyone's willing to swap a few leaves of this, I would like to hear from you.

it will not grow from leaves. You need seeds or tuber.
Normally if you start with one - and they do grow in terrarium only - you end with a clump of them - so you can separate the clump and get baby plants.
Members of the Gesneriad Society have an access to a seed fund for a nominal fee. Since you are interested in different and difficult gessies - consider joining this great group of people.
I am not sure that the seeds for this difficult plant are available. But - There is a Chapter of the Gesneriad society in CT - you probably get the best shot at contacting them and checking if members grow it and will give you a starter.

They won't grow from leaves? You'll have to explain that to me. I was transplanting muscicola seedlings a few weeks ago and had a few leaves that fell off but were in good shape, which I also planted in a terrarium environment. They seem to be establishing themselves, even though it's slow going. Thanks for the heads-up--Y'know I'll have to try at least once, if I can just get my hands on one!
I cannot guarantee that they will not grow from leaves. But the chance is small. S. muscicola is a cast iron plant in comparison. Plus - if you take a leaf from your plant and stick it in the soil now - it makes a great difference. The leaf that is shipped across the country - loses a lot of its viability.
rredbbeard this may be a little late, but i purchased a tuber of sinningia concinna on ebay from a grower. Lets hope it turns out to be one. It's been three months and the little guy just popped it's head out. You may want to look on ebay to see what's available. Otherwise if I'm actually successful at growing this (i'm a newbie) I would gladly share (since it seems there's not currently a listing for one on ebay) I would still keep an eye out for new listings. Hope that helps.
