### Black Oxford
Black Oxford is an apple cultivar listed as a standard apple, with fruit size in the standard class (5 cm or more in diameter) [S1]. Its origin is listed as Maine, and it is described as long keeping and productive [S2].
The packet gives no breeder, release year, or parentage information [S1][S2]. A trial note says it performed well when top grafted at Cedar Falls, Iowa; that is the only orchard management detail given [S2].
Black Oxford fruit is medium, roundish oblate, and slightly conical [S2]. The skin is yellow, nearly fully covered with dark brown-red color, with gray net veining and a note of peculiar color [S2]. It has many light dots with occasional larger russet dots, a deep russeted cavity, and irregular russet patches at the base [S2]. The flesh is whitish, firm, moderately juicy, mild subacid, and rated good [S2].
The season is March to May and it is described as long keeping, making storage duration a notable trait [S2].
An identification key context also links Black Oxford to a funnel-shaped tube, median stamens, ovate cells, and a black-red color note [S2]. Those structural notes help separate it from other red fruiting apples in keyed material [S2].
Hardiness evidence in this packet is limited. The Prairie Canada list gives fireblight as FB3 for this entry [S1], but no direct zone claim is provided, so a verified zone 1, 2, or 3 statement cannot be made from these records alone [S1]. In this packet, its value is mainly descriptive and diagnostic rather than a documented hardiness rating [S1][S2].
