Taxonomic notes

Synonym: Rhus copallina L.

There are three varieties: Rhus copallinum var. copallinum, R. copallinum var. leucantha, and R. copallinum var. latifolia[1].

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." - Radford et al 1964

"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." - Radford et al 1964

Distribution

Ecology

Habitat

R. copallinum habitats include old fields, oak-hickory woods, oak scrubs, marsh banks, roadsides, and sandridges[2].

Phenology

Blooms July to August[3].

Seed dispersal

Seeds are dispersed by birds[1].

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[4].

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[1].

Pollination

Use by animals

The foliage is a food source for the caterpillar Pyrrhia umbra who eat the flowers and drupes[5]. The berries are eaten by wild turkeys and songbirds[1]. 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. copallina[6].

Diseases and parasites

Fusarium wilt infects the roots, causing the leaves to droop and wilt[7].
