NatureServe Status

Global Status: G2
Global Status Last Reviewed: 29Feb2000
Global Status Last Changed: 19Jul1984
Rounded Global Status: G2 - Imperiled
Reasons: A species with an extremely limited range, and often just a few plants per occurrence: the Florida Natural Areas Inventory contains 78 occurrence records in its database, all located within Highlands and southern Polk counties, Florida. The species' habitat is decreasing in quality and extent as the southern portion of the Central Florida Ridge is developed.
Nation: United States
National Status: N2

Ecology & Life History

Basic Description: A much branched, herbaceous perennial with 1-several arching to ascending, wiry stems arising each year from an elongated taproot. Stem leaves are short and linear. Flowers are yellow, each obliquely curved to the right. (Based on Ward 1979, Kral 1983.)
Technical Description: Wiry, herbaceous to slightly woody perennial. Stems several, erect, wiry, branched near their tops, growing from a taproot, to 0.6 m tall. New shoots form in September and overwinter. Leaves linear-subulate, 1-6mm long, in widely-spaced pairs, minutely pustulate, rather succulent, those of the flowering stems erect or appressed. Flowers small, numerous, in the upper forks and towards the tips of the stems. Sepals unequal, 2-4-ribbed, broadly linear to ovate, 1-1.5 mm long. Petals five, yellow, 3-4 mm long, separate, obovate, asymmetrical (like the blades of a fan): the midnerve nearly lateral and an oblique blade on one side. Stamens numerous, grouped in 4's. Styles filiform. Capsule red to brown, 5-6 mm long, subulate-tipped, invested by the persistent perianth at the base, the 3 valves distinct, containing many minute seeds. (derived from Small 1933 and Martin 1987)
Diagnostic Characteristics: Plants with clusters of short branches with crowded, decussate, bladeless leaves at the base, and wiry, remotely scaly flowering stems which terminate in slender-branched cymes: petals marcescent: capsule dehiscent to the base; petals 5, yellow. (Small 1933)
Duration: PERENNIAL, Short-lived
Reproduction Comments: Insect pollination assumed from showy flowers; some members of the family are beetle-pollinated (Cronquist 1981). Distyly occurs in the genus (Ganders 1979). Aposporic apomixis and both self-fertilization and self-incompatibility are known from the genus (Asker & Jerling 1992).
Ecology Comments: Benefits from fire in the environment (Johnson 1981). Has been observed resprouting after fire (Menges & Kohfeldt 1994).
Terrestrial Habitat(s): Forest/Woodland, Shrubland/chaparral, Woodland - Conifer
Habitat Comments: Patches of open, nutrient-poor sand within oak and rosemary scrub. Often occurs with raindeer lichen (Cladonia spp.) and the rare wedge-leaved button snakeroot (Eryngium cuneifolium).

Population/Occurrence Delineation
Help
Group Name: Lake Wales Ridge 1 - EOSPECS

Minimum Criteria for an Occurrence: Any naturally occurring population of 1 or more individuals in suitable habitat.
Separation Barriers: Patches of dense vegetation that shade out patches of open sand and prevent seed germination and colonization form barriers between populations; also, agriculture, pine plantations, and development.


Separation Distance for Unsuitable Habitat: 1 km
Separation Distance for Suitable Habitat: 1 km
Alternate Separation Procedure: N/A
Separation Justification: Seeds for most of these species are dispersed by gravity, thus 1 km of suitable / unsuitable habitat appears to be sufficient to distinguish populations.
