Until you have a picture of the standard leaves and a ripe fig cut in half from stem to ostiole as well a picture of the ostiole, your probably not going get much of an answer. Even still, the variety may not be a common named variety, so you would have to settle with calling it something with the descriptor "Unknown" attached. Such as "Unkown Malta Dark" (or light, or yellow, or purple, or red....). You definitely cannot call it Malta Black because that named fig already exists(don't want to add any more confusion to the world of fig nomenclature), that is unless that's what it turns out to be. It also never hurts to include a common object in the picture with the fig so we can get a feel for the size of the fig( such as a ruler end with inches and centimeters on it).
Good luck rooting and welcome to the forum!
