Source: Received as seed from J.W. Porter grove near Hypoluxo, Palm Beach Co., Florida, 1928.

Parentage/origins: Parents unknown.

Rootstocks of accession: Carrizo citrange, C-35 citrange

Season of ripeness at Riverside: January to March

Notes and observations:

1985, EMN: Mr. Stow considers this the most important tree which came under his observation; believes it to be a most desirable stock for either lemons or oranges. This accession had exocortis, removed by shoot tip grafting.

2/26/1988, EMN: This looks and tastes like a typical sour orange to me; not a bitter sweet. Seems as acid to the taste as Seville sour, and certainly much more sour than Orlando bittersweet next door.

Availability: Not commercially available in California.
