Leaves are glabrous (smooth), 1-4 cm long, and deeply incised and toothed and is somewhat succulent (parts of the plant that are thicker) (Umber, 1979: 86, NatureServe, 2014). Branches are 0.02-0.20 cm long, and leaves that are (NatureServe, 2014). The flowers are arranged in slender spikes, salverform (a narrow tube with flat spreading terminal petals), and rose to purple (NatureServe, 2014). The fruits are 4 mm nutlets (Umber, 1979).

Regularity: Regularly occurring
Global Range: Brevard, Broward, Collier, Dade, Flagler, Hendry, Indian River, Levy, Martin, Monroe, Palm Beach, St. Johns, St. Lucie, and Volusia counties, Florida.
Similar to G. tampensis; distinguished by glandular haired calyx and leaf characteristics (leaves dentate to pinnatifid, somewhat succulent) (Wunderlin, 1982).
Comments: Sandy clearings in coastal dune swales, scrub, pinelands, and open live oak-cabbage palm woods (Kral 1983). Also found in disturbed clearings (L. Chafin, pers. comm. 3/96).
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 21 - 80
Comments: 58 occurrences as of 11/17/97.
Life History and Behavior
Reproduction sexual with no apomixis (Umber 1979). Fruits are small nutlets, probably self-dispersed.
National NatureServe Conservation Status
Rounded National Status Rank: N3 - Vulnerable
NatureServe Conservation Status
Rounded Global Status Rank: G3 - Vulnerable
Reasons: The number of element occurrences and number of individuals are relatively high, although the species' habitat is under great pressure from coastal development and is invaded by Casuarina. The number of collections and observations since 1980 is fairly low, but a high number of occurrences are on managed conservation lands.
Global Short Term Trend: Decline of 10-30%
Comments: Rapid coastal development has eliminated much of the dune habitat for this species.
Comments: Threatened by loss of habitat to residential and commercial development and to silviculture.
Biological Research Needs: Investigate reproductive biology of species. Provide land managers with information on biology of species for inclusion in management plans.
Names and Taxonomy
Comments: USFWS tracks as Verbena maritima (9/93).
