aceroides. Acer negundo. (Box
Elder) Semi-desert, foothills, montane.
Washes, streamsides. Spring. Box Elder is common along lower elevation streams, sometimes growing to 35 feet tall and 3 feet in diameter. Often there are many small branches at the base and along the knobby, distorted trunk. Box Elder is fast growing and its wood soft; branches often split from wind and snow. The genus name "Negundo" was apparently applied because of similarities between the leaf shape of Negundo aceroides and Vitex negundo. "Aceroides" is from the Latin and Greek for "similar to acers", i.e., similar to Maples. The genus and species were first named Acer negundo by Linnaeus in 1753. Moench renamed the plant Negundo aceroides in 1794. Acer negundo is the more widely accepted scientific name today. |

aceroides. Acer negundo. (Box
Elder) Semi-desert, foothills, montane.
Washes, streamsides. Spring. Box Elder is dioecious , i.e., male flowers are on one tree and female flowers are on another. In late spring the winged "helicopter" seeds (samaras) develop on the trees bearing female flowers; the samaras do not drop from the tree until they are quite dry and uniformly light brown. Box Elder leaves, especially the young spring leaves, are very similar in shape and color to Poison Ivy leaves. |
