South Florida History and Distribution: This is a prostrate, herbaceous perennial herb, with wiry stems that radiate out from a taproot, forming dense mats over exposed limestone and sometimes sand. It is endemic to pine rocklands in southern Miami-Dade County from the Cutler Ridge area north to what is now downtown Miami, but is extirpated north of South Miami. It differs from subsp.
adhaerens in that the leaves and stems are nearly hairless. It differs from subsp.
pinetorum in that the stems are prostrate instead of erect.
Using modern NatureServe criteria, we up-ranked this to Critically Imperiled in South Florida in June, 2018.
