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."[2]

"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 the 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."[2]

Distribution

This plant is a southeastern coastal plain endemic. It's found from southeastern South Carolina to Panhandle Florida, and west to Texas.[1]

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.[3] Associated species include Berlandiera pumila, Chrysopsis, Licania michauxii, Cnidoscolus stimulosus, Phlox pilosa, Rubus cuneifolius, and Solidago door.[3] Soils include sand and loamy sand.[3]

Phenology

L. caroliniense flowers from April through June.[3][4]

Seed dispersal

This species is thought to be dispersed by gravity.[5]

Fire ecology

Populations of Lithospermum caroliniense have been known to persist through repeated annual burns.[6]
