Please try our next iteration of the Michigan Flora Online here. Beginning on February 1, 2023, michiganflora.net will point to this new site.

The new site offers several benefits over the existing website, including real coordinate mapping, giving a clearer view of the density of documentation as well as more precision about plant distributions and their link to landforms. We will also have the ability to update species pages more regularly, both in terms of new collections and as more existing Michigan specimens are georeferenced. In addition, we have a better photo display, and offer indented keys.

A species of eastern Asia, widely cultivated for its distinctive winged branches and brilliant autumn foliage. It spreads occasionally to forests, thickets, and untended yards, sometimes forming dense stands. First collected in 1980 in Berrien Co.

This species is very distinctive  at all seasons if bearing the corky-winged twigs. However, plants spreading into natural areas sometimes lack the corky wings of cultivated strains.
