Description from The Citrus Industry Vol. 1 (1967)
"The English nurseryman, Thomas Rivers of Sawbridgeworth, imported this variety [Valencia] from the Azores Islands and catalogued it in 1865 under the name Excelsior (Coit, 1915). About 1870, he provided trees to S. B. Parsons, a Long Island Nurseryman, and in 1876 he sent trees to A. B. Chapman of San Gabriel, California. In the meantime, Parsons sold trees to E. H. Hart of Federal Point, Florida, where in 1877 the variety received the name Hart's Tardiff [Hart's Tardiff is also known as Hart's Late]."
