    DETAILED BOTANICAL DESCRIPTION

    [0035] The following detailed description sets forth the distinctive characteristics of Ridley 0808. The data which define these characteristics were collected from asexual reproductions of the original selection. Dimensions, sizes, colors, and other characteristics are approximations and averages set forth as accurately as possible. The plant history was taken on plants plants at approximately 3 years of age, and the descriptions relate to plants grown in the field in Tabulam, New South Wales, Australia. Descriptions of fruit characteristics were made on fruit grown in Tabulam, New South Wales, Australia. Color designations are from Tabulam, New South Wales, Australia. Except where otherwise designated, color notations are based on The Royal Horticultural Society Colour Chart, of The Royal Horticultural Society, London, 2015 edition.
