French, Arbre a poison, Sumac veneneux ;
German, Gift sumach, Wurtzel sumach.
A deciduous shrub, with reddish, branching stem, 1 to 3 feet high,
or climbing by rootlets over rock, etc., or ascending trees in which
latter case it becomes Rhus radicans. The leaves are alternate,
ternate, the lateral leaflets unequal at the base and sessile, the
terminal one larger at the end of a prolongation of the common
petiole (cauline differing from the radical), rhombic-ovate pointed
variously notched or entire, cut-lobed, downy beneath, thin; the
character of leaves somewhat inconstant, depending probably on the
situation and proximity of supporting objects. The small greenish-white
flowers are polygamous appear in June in loose and slender axillary
panicles. The whole plant has a resinous, milky, acrid juice, staining
black and extremely poisonous.
