yes the lip does move, and no, it does not stink.
I don't remember if it had a sweet fragrance though - I tend not to sniff flowers until someone asks......
Awesome! I have a small collection of gesneriads as well. Haven't collected them recently, but was pretty miffed this spring when a lady wouldn't sell me a variegated Chirita at the local arboretum's spring sale because she didn't know they were for sale. I went back the next day when someone more informed was working and they were sold out of them by then.
