Taxonomic notes
Synonym: Rhus copallina L.; R. leucantha Jacquin; R. obtusifolia (Small) Small; R. copallina var. leucantha (Jacquin) A.P. de Candolle
Varieties: Rhus copallinum Linnaeus var. copallinum, R. copallinum Linnaeus var. latifolia Engler
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." [1] "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." [1]
Distribution
Ecology
Habitat
R. copallinum habitats include old fields, oak-hickory woods, oak scrubs, marsh banks, roadsides, and sand ridges. [2]
Phenology
Blooms July to August. [3]
Seed dispersal
This species is thought to be dispersed by consumption by vertebrates. [4]
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. [5] Seed germination responds positively to heat shock with highest germination rates at 90 C.[6]
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. [7] Seeds respond positively to heat shock, suggesting that its germination is dependent on or facilitated by fire.[8]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Rhus copallinum at Archbold Biological Station:[9]
Colletidae: Colletes mandibularis
Halictidae: Augochlora pura, Augochlorella aurata, Augochloropsis sumptuosa, Lasioglossum pectoralis, L. placidensis
Leucospididae: Leucospis robertsoni
Megachilidae: Coelioxys sayi, Megachile xylocopoides
Pompilidae: Episyron conterminus posterus, Poecilopompilus interruptus, Tachypompilus f. ferrugineus
Sphecidae: Cerceris flavofasciata floridensis, C. tolteca, Ectemnius rufipes ais, Isodontia apicalis, Oxybelus decorosum, Palmodes dimidiatus, Philanthus ventilabris, Sphex ichneumoneus, Tachysphex similis
Vespidae: 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, Zethus spinipes
Use by animals
The foliage is a food source for the caterpillar Pyrrhia umbra. [10] The berries are eaten by wild turkeys and songbirds. [7] 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.[11]The fruits are used to make sweet drink by the Cherokee Indians.[12]
Diseases and parasites
Fusarium wilt infects the roots, causing the leaves to droop and wilt. [13]
