This is a Portugal early variety, an unknown cross, but one of the maternal varieties is probably the Mediterranean tangerine, usually referred to as t C. reticulata Blanco. 'Carvalhais' is widely cultivated in Portugal and sometimes also exported to other European countries.
It's an erect, vertically growing tree with typical long, pointed, spear-shaped leaves (leaves resemble those of Clementine 'Commune'). Its fruit is average or big, usually spherical or oval and has thick, strong, well attached orange rind (ripe fruit). 'Carvalhais' pulp is very juicy, slightly sour and contains lots of polyembrionic seeds. Ripe fruit can hang on the tree for a very long time without any significant quality loss, but this quality starts to fade really fast, after the fruit is harvested. Croatian nurseries propagate many clones from the Corsican research facility in San Giulianu (mainly those labeled as 'Carvalhais SRA 3', 'Carvalhais SRA 23' and 'Carvalhais SRA 25').
