NatureServe Status

Global Status: G2
Global Status Last Reviewed: 06Jun2008
Global Status Last Changed: 05Jan1985
Rounded Global Status: G2 - Imperiled
Reasons: Scattered about the western and central Florida panhandle and adjacent Alabama. In 2007, it was also found at one site in Georgia. Disturbance from recreational use of lakes and ponds, clearcutting, and residential development is having a severe impact on this species.
Nation: United States
National Status: N2

Number of Occurrences: 21 - 80
Number of Occurrences Comments: Approximately 50 to 80 locations are known.

Population Size Comments: Can be locally abundant.

Overall Threat Impact: Very high - high
Overall Threat Impact Comments: Highly threatened by land-use conversion, habitat fragmentation, and human disturbance (ATV use and mowing of pond margins), and to a lesser extent by forest management practices (Southern Appalachian Species Viability Project 2002). Threatened by erosion and run-off from pine plantations and developments which causes damage to shorelines and alters the hydrology of karst ponds (Chafin 2000).

Short-term Trend: Decline of 10-30%
Short-term Trend Comments: Recreational use of lakes and ponds by ORV's, clearcutting, and residential development has seriously impacted this species.

Ecology & Life History

Basic Description: An herbaceous perennial, usually stiffly erect, 2-3 dm tall. Leaves are opposite, variously shaped, 1.5-4 cm long with the blades twisted vertically. The flowers have a distinctive urn-shaped floral tube, and 4 showy, lavender-rose petals. (Based on Ward 1979.)
Technical Description: "Plant forming tubers at the ends of some roots. Stem rigid, simple or more commonly bushy-branched, mostly about 2 dm tall, sometimes to 5.5 dm, at midstem 4-angled, angles narrowly winged, the faces subequal, copiously glandular-pubescent. Leaves narrowly elliptic, oblanceolate or linear, 1.5-4 cm long, 1-5 mm wide, 3-nerved, the lateral nerves absent; leaf surfaces sparsely to copiously glandular-pubescent, margins with distant low, ascending glandular hairs. Cymes few to densely flowered. Mature floral tube (4-) 5-7 (-8) mm long, with scattered glandular pubescence, body globose, neck short-cylindrical, much shorter than the body. Calyx segments narrowly triangular. Petals broadly obovate to suborbicular, 11-12 mm long, deep lavendar-rose, smooth above, glandular-pubescent below (in bud at least). Seed about 0.7 mm long, with 3-5 prominent, broad, symmetrical or tortuous longitudinal ridges or contiguous domelike tubercles in lines" (Godfrey and Wooten, 1981).
Diagnostic Characteristics: Rhexia salicifolia may be characterized by bright lavendar-rose petals with hairs of the floral tube scattered rather evenly over the surface and by leaf blades turned to a vertical position, i.e., with their plane surfaces at right angles to the substrate (Godfrey and Wooten, 1981). Leaves are narrow, there are gland-tipped hairs at the leaf nodes, stems are equal-sided, and fruits are glandular-hairy with the neck shorter than the body (Chafin 2000).
Duration: PERENNIAL
Palustrine Habitat(s): FORESTED WETLAND, TEMPORARY POOL
Terrestrial Habitat(s): Sand/dune
Habitat Comments: Full sun in wet sandy or sandy-peaty areas of sinkhole pond shores, interdunal swales, margins of depression marshes, flatwoods ponds, and sandhill upland lakes (Kral 1983; Chafin 2000).
