Basic Description: A low, minty-smelling shrub growing to 0.5 m tall. Stems are stiff, ascending from a woody base. Leaves are variable in size depending upon their location on the stem. Flowers are about 1 cm long, cream-colored with purple-red spots.
Diagnostic Characteristics: Distinguished from Dicerandra frutescens by mint-camphor odor (vs. mint) cream-colored corolla (vs. white to pink), bright yellow anthers (vs. purplish-yellow), and shorter leaves (5-14 mm, vs 6-20 mm). These characters are not as obvious on herbarium specimens as in the field. (unpublished FNAI material in element file, Martin 1989)
Duration: PERENNIAL, Short-lived, DECIDUOUS
Reproduction Comments: Assuming reproductive information is similar to D. frutescens.
Terrestrial Habitat(s): Shrubland/chaparral
Habitat Comments: Openings in sand pine-oak scrub on yellow soils of the Central Florida Ridge.
