The genus name Stipulicida derives from the Greek meaning for fibers. The specific epithet setacea comes from the Latin word for bristle- which refers to the tiny leaves that resemble bristles.[1]
Description
A description of Stipulicida setacea is provided in The Flora of North America.
Distribution
Found along the Coastal Plain from Virginia down to Florida and west to Louisiana. It is critically imperiled in Virginia and Louisiana.[2]
Ecology
Habitat
In the Coastal Plain, S. setacea habitats include shrubless barrens, sandhill clearings in oak woodlands, sand pine-oak scrubs, longleaf pine-saw palmetto flatwoods, surrounding cypress wetlands, oak-hickory hammock forests, open oak-hickory-sand pine scrubs, and slash pine woodlands bordering tidal marshes. It occurs in disturbed areas such as powerline corridors, grassy roadsides, sandy old fields, parking areas, moist banks of drainage canals, and a pineapple field. Soil types include loamy sand, sand, and sandy peat. Associated species include Lupinus diffusus, Arenaria caroliniana, Opuntia, Parnoychia erecta, Polygonella robusta, Helianthemum, Vaccinium, and Crataegus.[3]
Phenology
S. setacea has white flowers, usually in clusters of three; with five petals, three stamen, and three lobed ovaries.[3] The flowers are not notched at the tips, unlike many members of this family.[4] The fruit is a small capsule with a small yellowish seed. Flowers March through June and fruits May through August.[3]
Seed dispersal
Seeds lack obvious dispersal mechanisms and is a poor disperser[5]. According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [6]
Seed bank and germination
It has been observed that the seed bank after fire in the Florida rosemary scrub was dominated by S. setacea[7][8]. Carrington (1997) observed there to be more seeds present in the bank than adults in the Florida rosemary scrub.
Fire ecology
S. setacea is a seeder species that occasionally resprouts after fire[5]. Post-fire, it has been observe to dominate the seed bank in the Florida rosemary scrub[7]. It has been observed growing in burned pinewoods[3].
Pollination
The following Hymenoptera families and species were observed visiting flowers of Stipulicida setacea at Archbold Biological Station: [9]
Halictidae: Lasioglossum nymphalis
Megachilidae: Anthidiellum notatum rufomaculatum
Vespidae: Leptochilus krombeini, Microdynerus monolobus
Conservation and management
Threats include shoreline and barrier island erosion and fire exclusion. Beneficial management practices include shoreline and island stabilization and prescribed burning or mowing[4].
Cultivation and restoration
