2a. var. negundo

A. negundo var. violaceum (G. Kirchn.) Jaeger

Twigs glabrous or glaucous, green to olive green or appearing pale purple to purple. Ovaries and fruits glabrous. 2n=26. April–May.

Common nearly throughout Missouri (mostly eastern U.S.; Canada). Bottomland forests, banks of streams, mesic upland forests in bottoms of ravines, and bases of bluffs; also shaded ditches and moist roadsides.

Although the separation of plants with glabrous vs. hairy twigs is relatively easy in Missouri material, there exists a nearly continuous range of variation from trees with nonglaucous twigs to those with grayish purple glaucousness on the twigs (sometimes separated as var. violaceum). Glaucous specimens are scattered throughout the range of the species in the state.
