    A—0 to 10 centimeters (0.0 to 3.9 inches);, dark gray (10YR 4/1), dry; weak fine granular structure; very friable; fragments; clear wavy boundary. Lab sample # FL1601301
    E1—10 to 20 centimeters (3.9 to 7.9 inches);, light brownish gray (10YR 6/2), dry; single grain; loose; fragments; clear wavy boundary. Lab sample # FL1601302
    E2—20 to 66 centimeters (7.9 to 26.0 inches);, light gray (10YR 7/1), dry; single grain; loose; fragments; abrupt wavy boundary. Lab sample # FL1601303. Upon review of original soil description it was determined that the E/Eg horizon was best labeled as an E2. Based off experience and many other descriptions, the gray matrix associated with this layer was not determined to be due to ponding water within the soil profile but rather to iron being moved out of the profile from weathering to help form the underlying spodic horizon. This layer is simply light gray (10YR 7/1) find sand. For that reason the g (indicating gleying or wetness) was removed and replaced with an E with the 2 indicating it being the second E horizon in sequence.
    Bh1—66 to 76 centimeters (26.0 to 29.9 inches);, very dark brown (10YR 2/2), dry; 1 percent medium faint mottles; weak fine subangular blocky structure; very friable; fragments; gradual wavy boundary. Lab sample # FL1601304
    Bh2—76 to 89 centimeters (29.9 to 35.0 inches);, very dark grayish brown (10YR 3/2), dry; weak fine subangular blocky structure; very friable; fragments; clear wavy boundary. Lab sample # FL1601305
    Bh3—89 to 102 centimeters (35.0 to 40.2 inches); black (5YR 2/1); 1 percent fine distinct mottles; moderate medium subangular blocky structure; friable; fragments; gradual wavy boundary. Lab sample # FL1601306. Color was added to from 1978 publication Characterization Data for Selected Florida Soils. Information was missing on previous description.
    BE—102 to 117 centimeters (40.2 to 46.1 inches); brown (10YR 5/3); single grain; loose; fragments; gradual smooth boundary. Lab sample # FL1601307. Changed original designation of Bw to BE based off local knowledge and experience in describing these soils in the field as well as comparing to the OSD, which this pedon represents. This allows this pedon description to better fit other Mandarin descriptions. Original designation was A'21&B3 and was converted to a Bw, which is not common below a spodic horizon in these soils.
    E'1—117 to 142 centimeters (46.1 to 55.9 inches);, light gray (10YR 7/2), dry; single grain; loose; fragments; gradual wavy boundary. Lab sample # FL1601308
    E'2—142 to 157 centimeters (55.9 to 61.8 inches);, white (10YR 8/1), dry; single grain; loose; 1 percent medium faint ; fragments; gradual wavy boundary. Lab sample # FL1601309
    E'3—157 to 185 centimeters (61.8 to 72.8 inches);, grayish brown (10YR 5/2), dry; single grain; loose; fragments; gradual wavy boundary. Lab sample # FL1601310
    B'h—185 to 203 centimeters (72.8 to 79.9 inches);, black (10YR 2/1), dry; 1 percent fine faint mottles; weak fine subangular blocky structure; friable; fragments. Lab sample # FL1601311. Original description had this horizon designated as a B'2h and a conversion was made to a Bh. The prime symbol was left off that conversion and was added here.
    C—203 to 229 centimeters (79.9 to 90.2 inches);, brown (10YR 5/3), dry; single grain; loose; fragments. Lab sample # FL1601312. Original description had this horizon designated as a B'3 and has since been converted to a Bw'. Cambic horizons are not common in these soils and especially this deep. Based off the original description and staff input originating from many years of describing these soils, it appears that this horizon should be designated as a C.
