Description

"Annual or perennial, pubescent or hispid herbs. Leaves usually alternate. Cymes leafy-bracteate, some flowers heterostylic; fruiting pedicels mostly erect or ascending. Calyx cleft into narrow lobes; corolla yellow, yellow-orange, or white (to blue), tubular to funnelform or salverform, throat pubescent, crested or open, lobes spreading and imbricate; anthers included; gynobase flat or depressed. Mericaps 4 or fewer, smooth or wrinkled, with a broad basal attachment scar, the scar often surrounded by a sharp rim." [1]

"Plant 3-10 dm tall, arising from a strong-staining taproot; stems simple or branched, very leafy, hirsute. Cymes dense, leafy-bracteate, elongate at maturity and loosely flowered; flowers heterostylic, all subtended by a bract. Calyx 6-8 mm long at anthesis, 8-10 mm long at maturity; corolla orange-yellow, funnelform, 13-25 mm long; anthers in short-styled flowers at the top of corolla tube and just below the appendages at the throat, style extending only to the middle of tube; anther in long-styled flowers near the middle of the corolla tube, the long style reaching to and beyond the top of the tube, the appendages weakly developed at the throat; corolla nectary 1-0lobed, villous at the base of tube; stigma terminal , minutely villosulous, bilobed. Mericaps white, smooth, often pitted, 3-3.5 mm long." [1]

Distribution

Ecology

Habitat

In the Coastal Plain in Florida and Georgia, L. caroliniense has been found in pinewoods and sand dunes. In human disturbed areas it has occurred in cut over secondary sandhill forest and along highways. [2] Associated species include Berlandiera pumila, Chrysopsis, Licania michauxii, Cnidoscolus stimulosus, Phlox pilosa, Rubus cuneifolius, and Solidago door. [2] Soils include sand and loamy sand. [2]

Phenology

L. caroliniense has been observed flowering from February to May.[2][3]

Seed dispersal

This species is thought to be dispersed by gravity. [4]
