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 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 that may create suitable conditions and maintain enough bare sand needed. It does not resprout 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

Polygonum dentoceras was observed at the Archbold Biological Station to host sweat bees from the Halictidae family such as Lasioglossum placidensis, wasps from the Leucospididae family such as Leucospis robertsoni, thread-waisted wasps from the Sphecidae family such as Bembecinus nanus floridanus, Cerceris blakei and Tachytes pepticus, and wasps from the Vespidae family such as Leptochilus krombeini and Stenodynerus beameri.[6] Additionally, P. dentoceras has been observed to host ground-nesting bees such as Andrena nigrocaerulea, aphids such as Aphis sp. (family Aphididae), bees from the Apidae family such as Bombus impatiens and Trigona spinipes, plasterer bees from the Colletidae family such as Colletes speculiferus, leaf-footed bugs from the Coreidae family such as Leptoglossus phyllopus, planthoppers from the Dictyopharidae family such as Scolops sulcipes, sweat bees from the Halictidae family such as Augochlora pura, Augochloropsis metallica and Lasioglossum pilosum, and plant bugs from the Miridae family such as Lygus lineolaris.[7]

Conservation, cultivation, and restoration

There are fewer than 150 populations of P. dentoceras remaining on the Lake Wales Ridge. The ridge is quickly being converted to urban and agricultural areas. This species requires a large-scale natural disturbance, such as fire, to maintain gaps in the scrub to allow for germination.[1]
