Description

"Annual or perennial herbs or vines, often armed. Leaves petiolate, entire to pinnatifid. Corolla rotate, 5 parted, the lobes spreading or reflexed. Anthers exserted, erect and connivent or sometimes spreading, opening by two terminal pores, filaments short, often pubescent. Berry 2-locular, mealy or fleshy." [1] "Erect, armed, weakly branched, stellate pubescent perennial, 2-8 dm tall. Leaves ovate to elliptic-lanceolate, 7-12 cm long, 3-8 cm wide, irregularly sinuate, lobed, or parted, both surfaces beset with sessile, stellate trichomes with 5-7 spreading rays and an elongate central ray. Racemes terminal, few-flowered; calyx tube 2-3 mm long, calyx lobes acuminate, 3-6 mm long depending on age; corolla white to purple, 2.3-3.1 cm broad, lobes ovate, spreading or reflexed; anthers erect, connivent, 7-9 mm long. Berry yellow, 1-1.5 cm in diam."[1]

Distribution

Ecology

Habitat

S. carolinense can be found in pinelands, floodplains, floodplain clearings, pine-oak woods, upland oak-hickory forests, grassy turf of berms, pine-palmetto flatwoods, wet hammocks, deciduous woodlands, river banks, bordering marshes, and seasonally wet depressions within thickets. [2] It can also occur at boat landings, roadsides, shrubby lake margins, cultivated watermelon fields, under bridges, roadside depressions, cultivated flower beds, powerline corridors, old fields, along hiking trails, disturbed slash pine woodlands, and cowpea fields. Associated species include Richardia scabra, Croton glandulosus, Ambrosia artemisifolia, Datura stramonium, Phytolacca, Amaranthus, Cyperus, Passiflora, Rubus, Ilex, Baccharis, Myrica, horsemint, morning glory, and evening primrose. [2] Soils include sandy soils, limestone, sandy loam, loamy sand, alluvial sands, black organic clay [2] and calcareous soils. [3]

Phenology

S. carolinense has been observed to flower and fruit April through November with peak inflorescence in May.[2][4]

Seed dispersal

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

Fire ecology

S. carolinense dominated the canopy coverage on herbicide-treated plots during the first year after treatment. [6]

Use by animals

It is an important summer food for bobwhites.[7]
