Acer negundo

Summary 5

Acer negundo is a species of maple native to North America. In Canada it is commonly known as Manitoba maple and occasionally as elf maple. Box elder, boxelder maple, ash-leaved maple, and maple ash are its most common names in the United States; in the United Kingdom and Ireland it is also known as ashleaf maple.

Unlike most other maples (which usually have simple, palmately lobed leaves), Acer negundo has pinnately compound leaves that usually have three to seven leaflets. Simple leaves are also occasionally present; technically, these are single-leaflet compound leaves.The leaflets are about 2–4 in long and 1+1⁄4–2+3⁄4 in wide with slightly serrate margins. Leaves have a translucent light green color and turn yellow in the fall.

Because of its leaflets' superficial similarity to those of poison ivy, Acer negundo saplings are often mistaken for the allergenic plant. While both poison ivy and Acer negundo have compound leaves composed of three leaflets with ragged edges, Acer negundo exhibits an opposite branching pattern, as opposed to the alternating pattern of poison ivy.[13] Like poison ivy, Acer negundo is also a noted riparian species, and can often be found growing along riverbeds and in wet soils generally
