Description

Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, S. auriculata can be found bordering mesic woodlands, longleaf pine turkey oak sand ridges (FSU Herbarium), palmetto flatwoods (FSU Herbarium; Olano et al. 2006), oak-saw palmetto scrubs (Foster and Schmalzer 2003), sandhill communities (FSU Herbarium; Reinhart et al. 2004), xeric longleaf pine woodlands (Peet and Allard 1993), and unburned scrubby flatwoods (Menges and Kohfeldt 1995). It can also be found along railroads, powerline corridors, and disturbed longleaf pine restoration sites (FSU Herbarium). Soil types include loamy sand (FSU herbarium; Foster and Schmalzer 2003) and sandy, siliceous, hyperthermic Ultic haplaquod of the Pomona series (Moore et al. 1982).
In habitats that include Pinus palustris, Quercus laevis, Q. incana, Sporobolus junceus and Licania michauxii, S. auriculata accounts for most of the groundcover density (Rodgers and Provencher 1999).
Phenology
Flowering has been observed in May and fruiting June through July (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by being consumed by vertebrates (being assumed). [1]
Seed bank and germination
It can reproduce by resprouting, clonal spreading, and seeding (Menges and Kohfeldt 1995).
Fire ecology
It increases in abundance after fire (Menges and Kohfeldt 1995). Its rapid recovery post-fire can be attributed to large specialized storage organs (Olano et al 2006). However, Greenberg found out that S. auriculata decreased to almost nonexistent following a May fire (2003), suggesting that season of burning is important for this species.
Pollination
The following Hymenoptera families and species were observed visiting flowers of Smilax auriculata at Archbold Biological Station (Deyrup 2015):
Apidae: Apis mellifera
Halictidae: Augochlora pura
Megachilidae: Coelioxys dolichos, Megachile mendica, M. xylocopoides
Deyrup (2002) observed these bees, Augochlora pura, Coelioxys dolichos, Megachile mendica, M. xylocopoides, Apis mellifera, Xylocopa micans, X. virginica krombeini, on S. auriculata.
Use by animals
S. auriculata was found in 5.5% of the Gopherus polyphemus scat [2] therefore, the gopher tortoise serves as an agent of seed dispersal.
