Taxonomic Notes
Synonym(s): Rhus toxicodendron; T. toxicodendron (Linnaeus) Britton; T. toxicarium Gillis; T. quercifolium (Michaux) Greene.[3]
Description
T. pubescens is a dioecious perennial that grows as a forb/herb, shrub, or subshrub.[2] Leaves are alternate, trifoliate and lobed. It can grow up to 10 ft (3 m) in height but is more commonly 2-4 ft (0.6-1.2 m).[4]
Distribution
Toxicodendron pubescens can be found from Long Island, NY south to north Florida, west to eastern Texas and inland to West Virginia, Tennessee, Missouri, and Kansas.[1]
Ecology
Habitat
This species is very common in sandhill and upland pine communities but can also be found in dry woodlands and dry rock outcrops in the Piedmont and mountains.[1] T. pubescens responds positively to agricultural-based soil disturbance in South Carolina coastal plain communities. This marks it as a possible indicator species for post-agricultural woodland.[5][6] T. pubescens responds negatively to soil disturbance by roller chopping in Northwest Florida sandhills.[7]
Toxicodendron pubescens is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[8]
Phenology
T. pubescens flowers from March through May and fruits from August through October.[1][4] Flowers are yellow and inconspicuous. Fruits are greenish white and 0.25 in (6.4 mm) in diameter.[4]
Seed dispersal
This species is thought to be dispersed by consumption by vertebrates. [9]
Fire ecology
A study in southern Alabama showed burns in the winter and spring produced a greater percent occurance of T. pubescens. Burns in the summer reduced the percent occurence.[10] However, it is common in research plots in native upland longleaf pine communities burned at 2-5 year intervals in May-July.[11]
Use by animals
T. pubescens consists of 10-25% of the diet of large mammals and 2-5% of the diet of small mammals and terrestrial birds.[2] Humans are studying the homeopathic abilities of Toxicodendron pubescens dilutions in anti-arthritic and anti-inflamation treatments.[12]
