Rhus toxicodendron, Linn. (Toxicodendrum vulgare, Mill. R. radicans, Linn. R. Toxicodendron var. radicans, Torr.). Poison Ivy. Poison Oak. Fig. 3018, p. 2678. Suberect and scrambling over walls and fences or high- climbing by aerial rootlets: lfts. ovate or rhombic, acute or short-acuminate, entire or sparingly dentate or sinuate, more or less pubescent beneath, 1-6 in. long: fls. greenish, in loose axillary panicles 1-3 in. long: fr. whitish, subglobose, 1/5in. across, remaining on the plant during the winter. Spring. Nova Scotia to Fla. west to Minn., Neb., and Ark. Em. 577.—It colors beautifully scarlet and orange in autumn, but is very poisonous to many and therefore should not be planted near places where persons are likely to come in contact with it; in such places it should rather be exstirpated. It is, however, very difficult to eradicate, for it spreads by suckers and each piece of root left in the ground sprouts again.— The plant described above is by some called R. radicans, Linn., and the name R. Toxicodendron is restricted to an upright shrubby form with pubescent crenate or crenately lobed lvs., native to the S. Atlantic states, also called R.quercifolia, Steud.; also several other closely related species have been distinguished.
