This variety of mandarin comes from a spontaneous mutation of the Clementina Fina, which originated in Nules (Castellón) in 1953. It is also known by the names Clementina de Nules, Nulesina, Nulesina, Clementina Reina and Clementina Victoria.
The tree has good vigor and development, an open growth habit, a flattened shape and dense foliage, with no thorniness on the branches and, if observed, only on suckers. On the trunk and main branches of adult trees, bulges corresponding to dormant buds usually appear. It has a tendency to produce one more or less uniform flowering, and later two or three more heterogeneous ones. The lanceolate leaves of different sizes are very typical of clementines. Pollen has high germination power. It is parthenocarpic and self-incompatible.
The clemenula mandarin is medium in size, larger than its parent. Good caliber and excellent quality. Without seeds, although it could present them with cross-pollination. Intense orange color, and prone to puffing when it reaches its natural maturity. Oblate shape.
It has an adequate content of high quality juice with adequate levels of sugars and total acids. The pulp is melting, leaving almost no residue when eaten. The rapid loss of juice after ripening prevents it from being kept on the tree beyond the end of January, even if the bark remains in good condition. This loss would produce the contraction of the pulp and is the cause of its tendency to puff.
