There are three geographically distinct varieties: var. brachystachya is only found in southern and south-central Florida and appears to be the most unique of the three varieties; var. cromii occurs primarily in North and South Carolina; var. polygama is widely distributed and appears to be sympatric with var. croomii.[1]
Description
A description of Polygonum polygamum is provided in The Flora of North America.
Distribution
P. polygamum is distributed throughout the Coastal Plain, from southeast Virginia to south-central Florida, west to Texas.[2]
Ecology
Habitat
In the Coastal Plain in Florida, P. polygamum can occur in seasonally wet depressions with Hypericum tenuifolium and Paronychia chartacea; and in xeric oak/saw palmetto scrubs. In disturbed areas it can be found in roadside ditches, clear-cut slash pine forests,wooded beach dunes; and dry sandy spoil material that has been pumped from the river during dredging operations.[3][4] Associated species include Liatris laevigata, Hypericum tenuifolim, Paronychia chartacea and Palafoxia integrifolia. Soil types include white sand and loamy sand.[3]
Phenology
Flowers in September and October[3] seed mature in winter.[5]
Seed dispersal
This species disperses by gravity.[6]
Seed bank and germination
Physical dormancy does not typically occur, however, some seeds possess a non-deep physiological dormancy.[7]
Pollination
Polygonum polygamum has been observed with ground-nesting bees from the Andrenidae family such as Perdita polygonellae.[8]
Additionally, P. polygamum has been observed at the Archbold Biological Station to host the following species:[9]
Plasterer bees from the family Colletidae: Colletes mandibularis
Sweat bees from the family Halictidae: Augochlorella aurata, Augochloropsis anonyma, A. metallica, Halictus poeyi, Lasioglossum nymphalis, L. placidensis, Sphecodes heraclei
Wasps from the family Leucospididae: Leucospis slossonae
Spider wasps from the family Pompilidae: Anoplius marginalis, Episyron conterminus posterus
Thread-waisted wasps from the family Sphecidae: Gorytes deceptor, Oxybelus decorosum, Tachytes distinctus, T. validus
Wasps from the family Vespidae: Eumenes smithii, Leptochilus republicanus, Pachodynerus erynnis
