2b. var. texanum Pax

A. negundo var. interius (Britton) Sarg.

Twigs densely short-hairy, not glaucous, green to olive green. Ovaries and fruits glabrous or short-hairy. April–May.

Scattered in the western half of the state and disjunctly in Lincoln County (mostly western and southern U.S.; Canada, Mexico). Bottomland forests, banks of streams, mesic upland forests in bottoms of ravines, and bases of bluffs; also shaded ditches and moist roadsides.

The var. interius is said to differ from var. texanum in its glabrous or nearly glabrous (vs. minutely hairy) ovaries and fruits, as well as its hairy (vs. glabrous) petioles. In Missouri material, there is no correlation between these characters, and a range of pubescence densities exists on the petioles. McGregor (1986b) suggested that individuals from Kansas and Missouri with hairy twigs and glabrous or nearly glabrous fruits might represent hybrids between var. negundo and var. texanum, but this requires further study.
