Cyclamen elegans - grows around the lower part of the Caspian sea. Resembles some forms of C.coum and I'm not entirely confident in distinguishing it from coum ssp. caucasicum. It is still fairly rare in cultivation with a reputation for difficulty. Luckily newer introductions seem to be a bit more amenable.
Flowers winter and early spring - much of the plants under the name are in fact C.coum.
