Polygonum polygamum, commonly referred to as october-flower,[1][2][3] is a species of flowering plant endemic to the US southeast coastal plain.[1]
Habitat
It grows in the xeric fire-dependent habitats of the region, including longleaf pine sandhill and Florida scrub.[1][3]
Conservation
The species is relatively widespread and can be locally abundant where suitable habitat persists. It, like other dry site endemics of the region, may face long-term threats due to habitat loss for real estate, agriculture, and pine silviculture.[1]
As an obligate heliophile,[3] the species cannot persist in areas with closed canopy and low sunlight exposure, so additional threats include fire suppression and invasive species.[1]
