Description
Densely branched, low shrub, less than 2.5 feet tall, with a strong minty odor. Leaves evergreen, opposite, needle-like; leaves in clusters, giving the branches a bushy look. Upper surface of leaves smooth and hairless; lower surface covered by densely matted but nearly invisible hairs (visible with magnification). Flowers usually in groups of 2 or 3. Flower 0.5 - 0.75 inches long, flower bent sharply upward, lower lip of flower threelobed, white to pale lavender-pink with a band of purple dots on the white throat. Calyx smooth or with a few short hairs[1].
Distribution
Conradina glabra is endemic to the sandhills along the eastern shore of the Apalachicola River in Liberty county, Florida. Most populations occur on privately owned silvicultural land, the only population on public land is found at Torreya State Park[2].
Ecology
Habitat
This species is endemic to the excessively drained sandhills east of the Apalachicola River in Liberty county, Florida. Many populations are found on privately owned land or pine plantations, the only public land with populations of C. glabra is Torreya State Park[3][2].
Phenology
Flowers and fruits March through June[3].
Fire ecology
Longleaf pine sandhill communities experience fire ever 1 to 10 years. Low-intensity fires have been observed to have a more positive effect on the survival of adult individuals than high intensity fires[4].
Conservation and Management
It is unclear of the historical range of C. glabra due to much of the land being converted to silviculture in the 1950s, before this species was discovered. Habitat modification as a result of logging, site preparation and conversion to silvicultural practices and fire suppression are the main threats to this species[2].
Cultivation and restoration
In 1990, a study by Gordon, transplanted populations of C. glabra from private silviculture lands to the Nature Conservancy property in Bristol, Florida. Seedling establishment was found to be high in burned areas[4].
