Acer
negundo L., [ACRNE, érable négondo, érable
à Giguère, érable du Manitoba] may have 3 leaflets
instead of the usual 5, but its compound leaves are arranged in opposite
pairs (2 per node) on the stems and the seeds are long and winged.
Hog-peanut,
Amphicarpa bracteata (L.) Fern., [APPBR, amphicarpe bractéolée,
amphicarpe monoïque], normally has 3 leaflets like Poison-ivy,
but it is a twining herbaceous vine (not woody), its purplish to whitish
flowers are pea-like and larger than those of Poison-ivy, and each of
the 3 leaflets in 1 compound leaf of Hog-peanut has 3 strong veins (the
midrib plus 1 big vein on each side) joining the leaflet stalk, whereas
Poison-ivy has only 1, the midrib.
Caution: Although this plant is not poisonous
to touch, as is Poison-ivy, its blue grape-like berries are poisonous
if eaten.
