Islamorada - are moderately deep to bedrock on similar landform positions.
Keylargo - are very deep soils to limestone bedrock on similar landforms.
Matecumbe - are very shallow soils to limestone bedrock on similar landforms.

SERIES ESTABLISHED: Monroe County, Florida, 1989.

REMARKS:
These soils were formerly classified as shallow, Lithic Haplosaprists and are revised here to the twelfth edition of the keys (2014).
Diagnostic horizons and features recognized in this typical pedon:

1. Histic epipedon - 0 to 20 centimeters (0 to 8 inches) (Oase horizon)
2. Lithic (shallow) contact - 20 centimeters (8 inches) (2R horizon)
3. Peraquic feature - the zone from 0 to 203 centimeters (0 to 80 inches).
4. Aquic conditions - endosaturation ranges from 0 to 203 centimeters (0 to 80 inches).
5. Sulfidic feature - the zone from 0 to 20 centimeters (0 to 8 inches) contains sulfidic soil materials.
