Description from The Citrus Industry Vol. 1 (1967):
" Genoa is a California variety which Webber (1943) says is of the Eureka type and difficult to distinguish from it. As the writer saw it in Chile, where it was taken from California and constitutes the principal variety, it appeared to be somewhat more vigorous, densely foliated, and cold-resistant. It was introduced into California about 1875 from Genoa, Italy, by Jose Rubio of Los Angeles. So far as the writer has been able to ascertain, it has achieved commercial importance only in Argentina and Chile. "
