Global Rank: G1 - Critically Imperiled

Date Inducted in National Collection: 02/25/1988

Description:

This rare mint, the Apalachicola rosemary, was listed as federally endangered in 1993. At that time, there were seven known locations of this species, six of which were on private timber company land. Since that time, the one population on State land has disappeared, but The Nature Conservancy discovered two new locations in or adjacent to one its preserves, and an exciting reintroduction effort was carried out. This Florida-endemic mint is a perennial shrub that grows to a height of 0.8 meters. The Apalachicola rosemary has linear, aromatic evergreen leaves. The upper surface of these leaves is smooth and hairless, while the lower surface is covered with dense hairs that are visible only with magnification. The flowers are white to pale lavender-pink flowers with a band of purple dots on the white throat. Flowers arise from the leaf axils in groups of 2 or 3.

Where is Apalachicola False Rosemary (Conradina glabra) located in the wild?

Habitat:

In Liberty County it occurs in flat sandy areas(characterized by longleaf pine and turkey or bluejack oak) that are deeply dissected by steep sided, moist ravines (Gray, 1965) Since Shinners did not determine this species to be taxonomically distinct until 1962, no one is sure of its exact habitat before the conversion of pine plantations in the 1950s. More recent occurrences have been found on the upper edge of steepheads in the transition to sandhills, edges of pine plantations, highway and utility right-of-ways (FNAI 2000).Not much is known about the Santa Rosa County population.

Distribution:

Endemic to Liberty and Santa Rosa Counties, Florida (Coile 2000).

States & Provinces:

Conradina glabra was reintroduced by The Nature Conservancy within protected areas of native habitat. Reintroduced specimens were monitored on a monthly basis and woody vegetation around it clipped at half the sites. During the first seson, removal of competition resulted in significantly taller plants with more branches and flowers. After the second season, treatment effects diminished. Survival was 94% prior to a prescribed fire at two of the three sites. Roughtly 25% of plants with 50-100% scorched tissue resprouted. Seedling establishment was highest at the burn sites and almost entirely limited to clipped plots.

This species has few known localities within a limited range: the Florida Natural Areas Inventory's database contains 10 occurrence records, all in Liberty County, Florida. Conversion of habitat to pine plantations, intensive forestry operations and management, pasture, roads and rights of way with maintenance and development threaten this plant.
