Description
"Glabrous, monoecious, perennial herbs or shrubs with alternate leaves. Leaves finely crenate, the teeth with pointed, callous spicules, sessile or short-petiolate. Spike terminal, rachis with numerous large glands, the lower portion pistillate flowered, the upper staminate. Calyx 2-3 parted, yellow; petals none; stamens 2; stigmas 3, red. Capsules as long as broad, leaving a 3-lobed disc upon falling from plant. Seeds grayish white, ovoid; caruncle small." [1]
"Herbaceous perennial, to 8 dm tall, with few to numerous stems arising from a crown; stems branching only immediately below an inflorescence with 2-4 branches. These usually terminated in an inflorescence. Leaves elliptic, 3.5-9 cm long, 1-4.5 cm wide; petioles 0-4 mm long, base glandular-stipulate. Spike 5-12 cm long. Capsules 8-10 mm long. Seeds nearly smooth, 5-6 mm long." [1]
Distribution
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, S. sylvatica can be found in sandhills (FSU Herbarium; [2]), pine flatwoods, open pine-oak woodlands, recently burned pine-oak scrubs, longleaf pine-wiregrass stands, longleaf pine-turkey oak-wiregrass, and annually burned pinelands (FSU Herbarium). Substrate types include loamy sand, sand (FSU Herbarium), and siliceous, hypothermic Ultic haplaquod of the Pomona series. [3]
Associated species include Stillingia aquatica, Phlox floridana, Asimina longifolia var. spathulata, Lactuca graminifolia, Pterocaulon undulatum, Asclepias humistrata and Quercus hemisphaerica (FSU Herbarium).
Phenology
It has been observed flowering April through July (FSU Herbarium).
Seed dispersal
It is dispersed explosively (up to 3 meters); seeds are forcefully expelled after the fruit matures and dries. It can also be dispersed by ants. [2] According to Kay Kirkman, a plant ecologist, this species disperses by explosion mechanisms or by ants. [4]
Seed bank and germination
Fire ecology
It seems to respond positively to burning. In an experiment by Greenberg (2003), and he noted that the percent cover of S. sylvatica was highest 16 months after a May burn. [5]
Pollination
Use by animals
The seeds of S. sylvatica contain elaiosomes and have been found in middens of Florida harvester ants, Pogonomyrmex badius. [2]
