Forgive the English translation by google, but I ran unto some info digging out Navelina and Ricalate navels. The info like this are hard to come by from UCR and other US websites.

It turns out that Navelina is among the cold hardiest of the navels and Ricalate can have navels stay much longer on the tree than Navelate. These are superb cultivars after all. I will try to graft Navelina on top of my Washington Navels to protect the tree from the frost, and also have two weeks earlier season sweet navels, at least sweeter than Washington navels.

Here's the crude info to decipher, the translator seems to be verbatim that sometimes the sentences are hard to make out clearly, knowing a little bit of spanish, I could improve the translation but have no time at the moment:

navelina
Its orange is of so large means with cleared form or slightly made oval, it does not have seeds and the pulp is very substantial. The skin is of an intense orange and has the prominent navel little. It is the more resistant variety of naranjo to the cold and the lime. It presents/displays tendency to the alternancia of harvests. He is productive, precocious, with a maturity index that takes an average of two weeks of advance with respect to the W. Navel. She is one of the cultivated varieties more. Their oranges are of great quality for consumption in fresh.


Navel Ricalate: It appears in the Shore of Cabanes in 1977 and comes from Washington Navel due to the mutation. The sale of orange of this class takes place as of 1990. Naranjo does not present/display thorns and has good vigor. The orange is of size somewhat smaller than the one of W. Navel, with made oval form and of color uniform orange, seemed to the NAVELATE, without getting to have as much clarity. He is something more delayed than the NAVELATE. It holds long time in the tree by his great adhesion to pedúnculo.

Salustiana: Commune comes from the variety, by spontaneous mutation in the province of Valencia. The tree is vigorous, of great size and with vigorous vertical branches. He is sensible to the cold. Its orange round or is slightly flattened, practically without seeds, fine skin and of so large means to great. It produces a juice of orange of sweet flavor, which makes be ideal variety for double aptitude of table and industry him. The orange can remain enough time in naranjo in good commercial conditions. Its harvesting is of February to March.

Joe:
I understand that we can order them through you. Right?

I will add them to your wish list

as agreed earlier.

Okay, here's my shot at more proper translation:

Navelina
Its clear bright orange fruit is slightly oval shaped, seedless, and large pulps. The skin is intense orange with a prominent little navel. It is the more cold hardy variety amongst the oranges and can tolerate lime soils. It tends to be alternate year bearing. Very productive, precocious, and matures about two weeks earlier than Washington Navel on the average. This is one of the more cultivated varieties in Spain. The fruits are of great quality for eating fresh.

Ricalate
Was first discovered in the Shore of Cabanes in 1977 as a sport mutation of Washington Navel. This cultivar was first commercialized in 1990. The orange tree is thornless and has good vigor. The fruit is somewhat smaller than that of of W. Navel, has oval form and of uniform orange color, similar to Navelate and almost indistinguishible. Harvested later than the NAVELATE. The fruits hold well on the tree because of stronger peduncle bond.
