Today is the first I have heard of it. I have been reading about it a a few differnt threads, and the reviews seem very positive. Is it a clemitine crossed with something, or just a totally different cultivar? Anyone know where to find one in FL? I thought I was done adding new trees but now after reading about the clemenule I have to find one.

It is a clementine. Originating from the town of Nule in spain.
And Oronule is a (limb) mutation of clemenule. Also from the town of Nule.
Both are relatively hardy. They are ripe before Christmas. This is the most common clementine we find in shops in autumn in France.

And:
The true Name of "Clemenules" is "Nules"....

So "Clemenules" is a synonym, like "de Nules", "Nulera", "Nulesina" and others, and all mean the "Nules" Clementine. A very good cropper, relative hardy and very tasty...
In Spain this variety is usually budded onto Carrizo Citrange, but as plantings expand to soils unsuitable for citrange some plantings on macrophylla rootstock showed promising results, even if TSS/TA are lower compared to fruits grown on citrange rootstock, but rich enough for the fresh fruit market.
Fruits are prone to get puffy if not harvested in time.
