Hi Kelo,
that variety can have a synonym (or lots of synonyms), it's not corretc to say that there is no "xxx" fig.
The University of Sassari (not the capital, the capital is Cagliari) Istituto di Coltivazioni Arboree (ICA-SS) has a collection field with these varieties:
BIANCA (LONGA) , BUFFOSA, BURDASCIOTTA BIANCA, BURDASCIOTTA NERA, BUTTADA, CALABRESE, CANA, CANAERA, CARCANZI TROTA, CRAXIOU DE PORCU, DE CASTEDDU, DE DUAS VIAS, DI SARROCH, MACCA, MARTINICA, MATTALÒ , MATTINIEDDA, MENDULINA, MONTELEONE, MONTELEONE VERDE, MONTINA, MURENA, MURRA, PERDINGIANA, PESSIGHINA, PETRELLI, RAMPELINA, SAN PIETRO, SASSARESE, VERDE, ZOCCHITTA.
I know that there is a collection field also in Oristano, but it's difficult to find info.
I don't know if they give cuttings for propagation, but they should, since their purpose is to preserve biodiversity.
If you manage to contact these institutes, let me know, i'd like to collaborate with them.
