Jacquinia keyensis is localized in the coastal strand; it grows mostly on coral exposures within the salt-spray community of the Monroe County keys, and Miami-Dade and Lee counties. It is listed as threatened by the state of Florida.

The name Jacquinia armillaris Jacquin has been misapplied to Florida material of J. keyensis.
