Morphological Description

Diagnosis: Leaflets pinnately veined; terminal leaflet elliptic to obovate; lateral leaflets narrower and coarsely few-toothed to entire; flowers appearing just before the leaves, greenish; petals absent; samaras ca. 25-35 mm long.


Notes: Stream banks, low woods. (Feb-)late Mar-Apr. Leaves with 3 leaflets can sometimes resemble and be confused with those of POISON-IVY. However, BOX-ELDER has opposite leaves in contrast to the alternate leaves of POISON-IVY and most other Anacardiaceae. This is by far the most common Acer in nc TX. (negundo: from the native name of Vitex negundo, because of supposed similarity of leaves)
