Description
A description of Polygonum dentoceras is provided in The Flora of North America.
Distribution
It is endemic to the ridges of central Florida[1].
Ecology
Habitat
It is found in the dry sands of Florida rosemary scrubs in central Florida[2]. It is a gap specialist and has allelopathic properties, specifically to grasses[3]
Phenology
Reproduces sexually and asexually[4]. Fruits and flowers all year[1].
Seed dispersal
Seed bank and germination
It is an obligate seeder[5].
Fire ecology
It is believed that P. dentoceras is not dependent on fire, however only depends on sufficient gaps[4]. It demonstrates allelopathic capabilities than may create suitable conditions to maintain enough bare sand needed. It does not rsprout after fire, Weekley and Menges (2003) observed that two years postburn, P. dentoceras had not recolonized most plots. This is an obligate seeder and will recolonize from seeds after time.
Pollination
