NatureServe Status

Global Status: G2
Global Status Last Reviewed: 27Jul2001
Global Status Last Changed: 27Jul2001
Rounded Global Status: G2 - Imperiled
Reasons: A Florida endemic that was formerly wide-ranging, but currently Florida Natural Areas Inventory's database contains only 24 occurrence records. These are from Brevard and Volusia counties on the east coast of Florida and Levy, Citrus, Hillsborough, Manatee, Sarasota, Collier, Pasco, and Pinellas counties on west coast. The species' habitat is under tremendous pressure from development.
Nation: United States
National Status: N2

U.S. & Canada State/Province Status
Due to latency between updates made in state, provincial or other NatureServe Network databases and when they appear on NatureServe Explorer, for state or provincial information you may wish to contact the data steward in your jurisdiction to obtain the most current data.

NatureServe Global Conservation Status Factors

Range Extent Comments: Element occurrences in Brevard, Collier, Citrus, Levy, Hillsborough, Manatee, Pasco, Sarasota, and Volusia counties. Wunderlin (Atlas, 1996) also reports stations in Flagler, Indian River, Lee, and Pinellas counties. Coile (1996) also reports specimens from Hernando and Orange counties. Many of these occurrences are historic.

Number of Occurrences: 21 - 80
Number of Occurrences Comments: Twenty-four occurrences as of July 2001, twelve of which are post-1980.

Overall Threat Impact Comments: Loss of habitat through coastal and upland commercial development.

Short-term Trend: Decline of 10-30%
Short-term Trend Comments: Most collections and observations are pre-1980. Habitat conversion has greatly impacted this species.

Intrinsic Vulnerability Comments: May respond positively to burning and other disturbance that creates sandy openings.

Ecology & Life History
Help
Basic Description: Perennial herb from a short, shallow rhizome or from short lateral offshoots. Quadangular stems decumbent, rooting from lower nodes. Leaves opposite, ovate, acute, 4-6 cm long, the margin unevenly coarse serrate, with long (1-3 cm), winged petiole. Inflorescence a compact spike, elongating with age, with slightly irregular, salverform, purple flowers. Differs from Glandularia maritima by a shorter corolla tube and less divided leaves, although intermediates exist.
Technical Description: Stems and branches usually diffuse and erect, ascending or decumbent, mostly 3-6 dm long, glabrate or minutely pubescent. Leaves lanceolate to ovate-lanceolate, elliptic or rhombic-ovate, 2-8 cm long, toothed or incised or sharply lobed, serrate. Flowers in short spikes or corymbose spikes, calyx about 10-15 mm long, the longer lobes bristle tipped up to 3 mm long, corolla tube about 1.5 cm long, purple. Fruit of 4 oblong-linear nutlets ca. 4 mm long, coarsely pitted (Kral, 1983; Long and Lakela, 1971; Small, 1933).
Diagnostic Characteristics: Calyx eglandular, strigose; leaves incised-dentate, chartaceous; nutlet commisure 1/3 to 1/2 the width of nutlet, rounded at top (Wunderlin, 1982). Distinction from G. canadensis and G. maritima can be a problem; there are intermediates and strongest character to separate is not distinct.
Duration: PERENNIAL
Ecology Comments: Often found in disturbed areas & in or by recent clearings (Kral 1983).
Terrestrial Habitat(s): Forest Edge, Forest/Woodland, Old field, Sand/dune, Shrubland/chaparral, Woodland - Mixed
Habitat Comments: Sandy coastal hammocks and dunes, clearings, well-drained live oak-slash or longleaf pine-saw palmetto flats, and disturbed areas (Kral 1983).
