Basic Description: An erect, usually unbranched perennial herb, growing to 1 m tall. Stems are minutely hairy. Leaves are narrow, dotted with glands, and 4-7 cm long. Flower heads are numerous, usually 1 terminating each flowering stem. Flowers are all discoid and are bright purple in color. (Based on Taylor 1992, Hall 1993.)
Technical Description: Plants with a tuberous-thickened, cylindric, segmented primary root; stems 3-10 dm tall, villous-puberulent. Leaves numerous, glabrous or nearly so, all linear and only 1-2.5 mm wide, the lowermost ones up to 15 cm long but commonly deciduous, the others mostly 3-8 cm long, gradually reduced upward. Heads mostly 3-30 in an open-corymbiform to very openly racemiform inflorescence, on arcuate or ascending-spreading peduncles mostly 1.5-7 cm long, relatively very large, the involucre mostly 17-23 mm high, its bracts loosely erect, obtuse or broadly rounded, subherbaceous with scarious and ciliolate margins, sometimes partly anthocyanic; flowers ca. 20-30, the corolla ca. 2 cm long including the 5-8 mm lobes, glabrous within. Achenes 7-10 mm long; pappus strongly barbellate, inconspicuously biseriate, the outer series somewhat the shorter. (Cronquist 1980)
Diagnostic Characteristics: Pappus of barbellate, not plumose, bristles; heads distinctly pedicellate, large (with mostly 14-many flowers, and involucre mostly over 17mm high); bracts of the involucre obtuse or rounded; leaves very narrow. (Cronquist 1980, Wunderlin 1982)
Duration: PERENNIAL
Reproduction Comments: Flowers all sexual and perfect (Cronquist 1980). Pollination assumed biotic from showy flowers. Assumed wind-dispersed from pappus.
Ecology Comments: Resprouts after fire (Menges & Kohfeldt 1994). Restricted to sand pine scrub habitat.
Terrestrial Habitat(s): Forest/Woodland, Sand/dune, Shrubland/chaparral, Woodland - Conifer
Habitat Comments: Openings in oak-rosemary scrub, sand pine scrub.

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.
