Taxonomic notes
Synonym: Rhus copallina L.; Rhus leucantha Jacquin; Rhus obtusifolia (Small) Small.[1]
Varieties: R. copallinum Linnaeus var. latifolia Engler.[2]
Description
"Upright shrubs or small trees, not poisonous. Leaves once-pinnately compound. Inflorescence a terminal panicle. Drupes red, ripening in the autumn. Seeds smooth. Flowers produced after the leaves."[3] "Rhizomatous shrub or small tree to 7 m tall; stems densely short-pubescent. Leaflets 9-23 (mostly 9-11), sessile, oblong to elliptic, 3-8 cm long, 1-4 cm wide, acute to acuminate, entire or less frequently crenate to serrate, base cuneate to rarely rounded, glabrous or densely pubescent beneath; rachis winged. Panicle 0.5-3 dm long and usually as broad. Drupe densely short-pubescent, 3-4 mm broad. Seeds 2.5-3 mm long."[3]
Distribution
Ecology
Habitat
R. copallinum habitats include old fields, oak-hickory woods, oak scrubs, marsh banks, roadsides, and sand ridges.[4]
R. copallinum has shown regrowth in reestablished longleaf pine woodlands that were disturbed by agriculture in South Carolina coastal plain communities, making it a possible indicator species for post-agricultural woodlands.[5] It increased its cover in response to clearcutting and chopping in north Florida flatwoods.[6] This species also increased its frequency in response to roller chopping in east Texas hardwood forests.[7]
It was unaffected by agriculture in South Carolina pine woodlands.[8]
R. copallinum had variable changes in frequency in response to soil disturbance by a KG blade in east Texas. It either showed regrowth or resistance to regrowth in reestablished hardwood forests that were disturbed by this practice.[7]
Rhus copallinum is frequent and abundant in the Clayhill Longleaf Woodlands and Upper Panhandle Savannas community types as described in Carr et al. (2010).[9]
Phenology
This species has been observed to flower from July to August.[10][11]
Seed dispersal
This species is thought to be dispersed by consumption by vertebrates.[12]
Seed bank and germination
The rhizomes, flowers, fruits, senescent leaves and leaf litter contain toxins that significantly inhibit both seed germination and seedling growth of climax prairie and weedy species.[13] Seed germination responds positively to heat shock with highest germination rates at 90 C.[14]
Fire ecology
Fire stimulates root and root collar sprouting along with enhancing germination, making this a fire-climax species. Density declines 3 to 4 years following a fire, with fire exclusion reducing density and cover.[15] Seeds respond positively to heat shock, suggesting that its germination is dependent on or facilitated by fire.[16] Populations of Rhus copallinum have been known to persist through repeated annual burns.[17][18][19]
Herbivory and toxicology
Rhus copallinum has been observed at the Archbold Biological Station to host a variety of bee species such as Colletes mandibularis (family Colletidae), members of the the Halictidae family such as Augochlora pura, Augochlorella aurata, Augochloropsis sumptuosa, Lasioglossum pectoralis and L. placidensis, members of the Megachilidae family such as Coelioxys sayi and Megachile xylocopoides, as well as wasps from the Pompilidae family such as Episyron conterminus posterus, Poecilopompilus interruptus and Tachypompilus f. ferrugineus, members of the Sphecidae family such as Cerceris flavofasciata floridensis, C. tolteca, Ectemnius rufipes ais, Isodontia apicalis, Oxybelus decorosum, Palmodes dimidiatus, Philanthus ventilabris, Sphex ichneumoneus and Tachysphex similis, as well as Leucospis robertsoni (family Leucospididae) and members of the Vespidae family such as Eumenes fraternus, Monobia quadridens, Pachodynerus erynnis, Parancistrocerus fulvipes rufovestris, Parancistrocerus perennis anacardivora, Parancistrocerus salcularis rufulus, Polistes dorsalis hunteri, Stenodynerus beameri, Stenodynerus pulvinatus surrufus, Vespula maculifrons, Vespula squamosa and Zethus spinipes.[20] Additionaly, R. copallinum has been observed to host members of the Andrenidae family such as Andrena brevipalpis, A. crataegi, A. miserabilis and A. robertsonii, Bombus griseocollis (family Apidae), Tibicen tibicen (family Cicadidae), Oecleus borealis (family Cixiidae), Harmonia axyridis (family Coccinellidae), members of the Colletidae family such as Colletes speculiferus and Hylaeus modestus, Agapostemon virescens (family Halictidae), and members of the Megachilidae family such as Megachile albitarsis, M. brevis, M. petulans, and M. texana.[21] The foliage is a food source for the caterpillar Pyrrhia umbra.[22] The berries are eaten by wild turkeys and songbirds.[15] Birds have been observed to choose fruits of R. copallina rather than fruits of R. glabra when they were both available as winter foods. This could be due to the higher caloric value and larger fruits of R. copallinum.[23]
Diseases and parasites
Fusarium wilt infects the roots, causing the leaves to droop and wilt.[24]
Conservation, cultivation, and restoration
Cultural use
The fruits are used to make a sweet drink by the Cherokee Indians.[25] The drink was similar to what we think of as pink lemonade. Additionally, boiling the berries can create a cure for sore throats.[26]
