The starch-rich stems and roots were a main source of flour for the native peoples of southeastern N. America, and some people still prepare it today. These peoples are attributed with increasing the plant’s distribution. The plants were exploited on a commercial basis for the production of starch in the 19th and early 20th century, but this led to huge population losses of the Cycads to the point where there were no longer sufficient plants to make it profitable to exploit them[

The species is abundant across its range but has declined substantially in parts of Florida over the past 90 years (estimated at 20%) mainly due to habitat destruction for housing developments and agriculture. It has therefore been classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2011)[

Species in this genus form structures known as coralloid roots. These roots branch off from the taproot or secondary roots and are distinctive in that they grow laterally or upward, forming a nodular mass at the apex. These coralloid roots occur slightly below or slightly above the soil surface and generally contain cyanobacteria, also known as blue-green algae. These are able to fix atmospheric nitrogen and make it available as a nutrient to the plant. The ability to extract this important nutrient from the air explains how many cycad species are able to survive on almost sterile soils[

]. To make flour, the roots are first chopped into pieces. They are then pounded with a mortar and pestle. The pulp is then washed with water and the starch is allowed to settle to the bottom. Then the water is drained and the remaining paste is left to ferment for several days. At the end of the fermentation process, the starch is set in the sun to dry. When dry, the powdery, cornmeal-like flour is baked into bread[
