Taxonomic notes
Synonym: Rhus vernix Linnaeus.[1]
Description
In Radford (1964) this species is recognized as a synonym under Rhus vernix which is where this description originated from. "Inflorescence of axillary panicles on new wood. Drupes white or gray, the mesocarp dry, shattering at maturity. Seeds grooved. Flowers proceed simultaneously with the leaves." -Radford et al 1964
"Glabrous shrub or small tree. Leaflets 7-13, elliptic oblong or oblanceolate, 5-12 cm long, 2-5 cm wide, acute to acuminate, entire, bae cuneate; rachis not winged. Panciles 3-5 in the lower leaf axils, drooping or spreading, 1-2 cm long. Drupe glabrous, 5-7 mm broad." -Radford et al 1964
Distribution
Ecology
Habitat
Toxicodendron vernix has been documented in pine-wiregrass savannas; floodplain woodlands; swamp floodplans; mixed pinewoods; hillside bogs; swamps; bogs; low woods below dams; sphagnum shrub-bog; tamarack bog; wooded swamp; a thicket in loamy sand; and on a berm at the water's edge.[2] It has been found in disturbed habitats such as seepage areas, powerline corridors, wet thickets, cut over swamps, and roadside ditches. It has been observed in loamy sand.[2]
Associated species include Decodon, Rhododendron austrinum, Magnolia grandiflora, Myrica, Ilex, Viburnum nudum, Typha, Cornus, Lysimachia thyrsiflora, and titi.[2]
Phenology
It has been observed flowering April through August and fruiting February through October.[2][3]
Diseases and parasites
"A severe contact poison causing extreme inflammation, swelling and itching in susceptible individuals." -Radford et al 1964
Conservation, cultivation, and restoration
Cultural use
The resin of Toxicodendron vernix contains a harmful skin irritant called urushiol[4] that should be avoided by all as the degree to which the irritation occurs varies between the individuals exposed.[5] All parts of this species may contain this irritant.[6][7] Symptoms of exposure generally include a rash, swelling, and blisters and may present immediately or be delayed for up to a few days.[8]
