TYPE LOCATION: Marion County, Florida; approximately 4.0 miles east of Citra. NW 1/4, SW 1/4, Sec. 29, T. 12 S., R. 23 E.
RANGE IN CHARACTERISTICS: Solum thickness is 50 or more inches. Reaction ranges from extremely acid to strongly acid throughout. Depth to the Bh horizon ranges from 12 to 24 inches from the surface and depth to the Btg horizon ranges from 20 to 35 inches.
The A or Ap horizon has hue of 10YR or 2.5Y, value of 2 to 5, and chroma of 2 or less. Texture is sand or fine sand.
The Eg horizon has hue of 10YR or 2.5Y, value of 5 to 8, and chroma of 2 or less. Texture is sand or fine sand.
The Bh horizon has hue of 5YR to 10YR, value of 2 or 3, and chroma of 3 or less; or there is no dominant color and it is multicolored in shades of brown and black. Texture is sand, fine sand, loamy sand, or loamy fine sand.
The E'g horizon, where present, is less than 6 inches thick. It has the same range in colors and textures as the Eg horizon.
The Btg horizon has hue of 10YR to 5Y, value of 5 to 7, and chroma of 2 or less. Redoximorphic accumulations in shades of brown, yellow, and red range from few to many. Texture is sandy clay. Some pedons have thin layers, less than 8 inches thick, with textures of sandy clay loam or clay loam.
COMPETING SERIES: There are no known series in the same family.
GEOGRAPHIC SETTING: Lynne soils are on flatwood areas of Peninsular Florida. Slopes range from 0 to 2 percent. They formed in sandy and loamy marine sediments. The climate is humid subtropical. The average annual precipitation ranges from 56 to 62 inches and the average annual temperature ranges from 70 to 74 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These include the Adamsville, Electra, Myakka, Pomona, and Tavares soils. The somewhat poorly drained Adamsville and Electra soils are on slightly higher positions. In addition, Adamsville soils do not have argillic or spodic horizons and are sandy throughout while Electra soils have spodic horizons more than 30 inches below the surface and argillic horizons more than 37 inches. The very poorly or poorly drained Myakka soils are on similar positions, have spodic horizons more than 30 inches below the surface, and do not have argillic horizons. The very poorly or poorly drained Pomona soils are on lower positions and have argillic horizons more than 37 inches below the surface. The moderately well drained Tavares soils are on higher positions, do not have spodic or argillic horizons, and are sandy throughout.
DRAINAGE AND PERMEABILITY: Poorly drained; moderately slow permeability.
USE AND VEGETATION: Most areas of Lynne soils remain in native woodland. A few areas are used for truck crops, pasture, and range. The native vegetation consists of slash pine, longleaf pine, creeping bluestem, chalky bluestem, indiangrass, panicum, pineland threeawn, saw palmetto, fetterbush, gallberry, and wax myrtle.
DISTRIBUTION AND EXTENT: Peninsular Florida. The series is of moderate extent.

REMARKS: Diagnostic features and horizons recognized in this pedon:
Ochric epipedon - the zone from 0 to 20 inches (A, Eg1, and Eg2 horizons).
Spodic horizon - the zone from 20 to 33 inches (Bh1 and Bh2 horizons).
Argillic horizon - the zone from 33 to 67 inches (Btg1 and Btg2 horizons).
A seasonal high water table is within 12 inches of the surface for 1 to 4 months in most years.
