Regularity: Regularly occurring
Global Range: Arnoglossum floridanum occurs in 29 counties in Florida, from Madison and Taylor Counties east to Duval County and south to Brevard, Highlands, and Manatee Counties. There are no validated Georgia records.
Comments: Longleaf pine/oak/wiregrass sandhills, dry longleaf pine/oak/palmetto flatwoods, sand pine scrub, and along roadsides and clearings through such habitats.
National NatureServe Conservation Status
Rounded National Status Rank: N3 - Vulnerable
NatureServe Conservation Status
Rounded Global Status Rank: G3 - Vulnerable
Reasons: Fairly widespread. Well distributed throughout range. Not difficult to find in proper habitat, but tends to have localized, scattered populations. Several protected populations. Threats operate mostly on private lands and on long-term scale but there is a general declining trend due to loss of habitat.
Global Short Term Trend: Decline of 10-30%
Comments: General decline due to loss of habitat.
Comments: Threats include loss of habitat from agriculture and citrus crops, pine plantations, suburban sprawl, commercial development. Fire suppression is a constant threat in areas not under a fire management plan.
Names and Taxonomy
Comments: The genus name "Cacalia" was used for a group of plants now generally recognized as belonging to eight genera, and has been variously used for differing portions of that group. In 1998, the Committee for Spermatophyta published (Taxon 47: 444) its decision to reject this name nomenclaturally, in order to avoid confusion. Thus, all plants formerly called Cacalia must now be classified into other genera. LEM 3Jun98.
