Regularity: Regularly occurring
Global Range: Found only in Highlands County on Lake Wales Ridge - very narrow range in highly endangered Florida scrub community on the southern end of the Lake Wales Ridge - map given in Bridges and Orzell shows about 600 square km (60km X 10 km) (Bridges and Orzell 2002)
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 6 - 20
Comments: 11 sites seen within last 20 yrs (6 verified around the year 2000 and 5 found by Christman in 1988 scrub survey), plus 3 historical sites (checked around 2000 and not found) and 2 herbarium sites not checked (Bridges & Orzell 2002).
National NatureServe Conservation Status
Rounded National Status Rank: NNR - Unranked
NatureServe Conservation Status
Rounded Global Status Rank: G1 - Critically Imperiled
Reasons: Fewer than 20 known sites and probably fewer than 1000 plants total in the 11 extant populations; endemic to highly restricted habitat which is being rapidly developed in Florida.
Environmental Specificity: Narrow. Specialist or community with key requirements common.
Comments: Low areas where seasonal mositure is available surrounded by deep white sands of oak scrub or rosemary balds on Lake Wales Ridge- tolerates some disturbance - often found in sand roads through scrub.
Global Short Term Trend: Decline of 10-30%
Comments: Bridges and Orzell (2002) mention 3 previously known sites could not be re-located.
Global Long Term Trend: Unknown
Degree of Threat: Very high - high
Comments: Natural uplands on Lake Wales Ridge are rapidly being developed as land values in that portion of Florida have recently risen steeply; existing scrubs are becoming overgrown due to lack of fire.
Biological Research Needs: Archbold Biological Station is monitoring the species (contact=Carl Weekley).
