A description of Syngonanthus flavidulus is provided in The Flora of North America.
S. flavidulus can be found in Alabama, Florida, Georgia, North Carolina, and South Carolina. It is ranked vulnerable in North Carolina and imperiled in Mississippi and South Carolina.
In the Coastal Plain in Florida, S. flavidulus habitats include pine-oak woodlands, wet pine flatwoods, margins of cypress wetlands, sphagnous bogs, and powerline corridors. S. flavidulus grows in areas of copious ground water seepage in poorly drained soils and sandy loam.
S. flavidulus had mixed changes in biomass in response to heavy silvilculture in north Florida flatwoods. It has shown both regrowth and resistance to regrowth in reestablished flatwoods that were disturbed by these practices. It increased in frequency and biomass in response to soil disturbance by clearcutting and chopping in north Florida flatwoods forests.
Syngonanathus flavidulus is an indicator species for the Central Florida Flatwoods/Prairies community type as described in Carr et al. (2010).
Associated species include Lachnocaulon digynum, Sarracenia psittacina, Xyris drummondii, Drosera capillaries, Eriocaulon decangulare, Eryngium integrifolium, and Oxypolis filiformis.
Syngonanthus flavidulus flowers May through July.
Seed bank and germination
This species was found viable in the seed bank of Florida pine flatwoods communities following fire after over 30 years of fire exclusion.
It has been observed growing in an annually burned longleaf pineland.
Various Hymenoptera species were observed visiting flowers of Syngonanthus flavidulus at the Archbold Biological Station. These include plasterer bees from the Colletidae family (Colletes sp. and Hylaeus sp.), sweat bees from the Halictidae family (Agapostemon splendens, Augochlorella gratiosa, Augochloropsis sumptuosa, Halictus poeyi, Lasioglossum coreopsis, L. lepidii, L. nymphalis, L. puteulanum, L. tamiamensis and Sphecodes heraclei), wasps from the Leucospididae family (Leucospis robertsoni and L. slossonae), leafcutting bees from the Megachilidae family (Anthidiellum perplexum, Dianthidium floridiense, Hoplitis truncata and Megachile georgica), spider wasps from the Pompilidae family (Anoplius sp., Aporinellus apicatus and Episyron conterminus posterus), thread-waisted wasps from the Sphecidae family (Ammophila pictipennis, Bicyrtes capnoptera, Cerceris blakei, C. compar, Ectemnius decemmaculatus tequesta, E. rufipes ais, Hoplisoides placidus placidus, Microbembex monodonta, Oxybelus decorosum, O. laetus fulvipes, Philanthus ventilabris, Prionyx thomae, Stictiella serrata, Tachysphex apicalis, T. similis), and wasps from the Vespidae family (Leptochilus krombeini, L. republicanus, Pachodynerus erynnis, Parancistrocerus bicornis, P. fulvipes rufovestris, P. histrio, P. perennis anacardivora, P. salcularis rufulus, P. vagus slossoni, Pseudodynerus quadrisectus, Stenodynerus histrionalis rufustus, S. lineatifrons). Additionally, the leafcutting bee Anthidiellum notatum (family Megachilidae) was also observed on this species.
