Source: Received as budwood from Dr. Fawcett's #89, Florida collection, 1914.

Rootstocks of accession: Carrizo citrange, C-35 citrange

Description from The Citrus Industry Vol. 1 (1967):
Fruit medium-sized, globose to slightly oblong; seeds comparatively few. Well-colored under favorable conditions. Rind medium-thin and slightly pebbled. Flesh color light orange; medium-tender, juicy; flavor rich. Midseason in maturity.
Tree vigorous, upright, with rather stiff thornless branches and stout branchlets; precocious, and prolific.
This variety, not to be confused with the Jaffa, originated in 1877 from seed imported from Joppa, Palestine, by A. B. Chapman of San Gabriel, California. It never attained commercial importance in California or in Florida, where it was early introduced, but it was popular for some decades in South Africa and still has limited importance in Texas.
In comparison with Jaffa, the fruit averages smaller and is less oblong, the rind texture is finer, and the season of maturity is earlier. The tree is more upright, has thicker branchlets, and is more precocious. In general appearance, Joppa resembles Shamouti more than Jaffa. In South Africa, it is reported (Marloth and Basson, 1955) that on rough lemon rootstock Jaffa and its seedlings exhibit budunion "crease" whereas Joppa and its derivatives do not. Addorosa is a local synonym in South Africa. The Fukuhara variety of Japan is considered to be a bud variation of Joppa."
Availability: Not commercially available in California.
