This may be combined with A. glandulosa (Wallroth) Momiyama (FNA 12; W).These East Asian taxa differ from native cordata as follows (W): leaves 3-5 lobed (versus unlobed to shallowly 3-lobed); young twigs purplish (versus green), sparsely puberulent or sometimes glabrate (versus glabrous). A. brevipaniculata is a frequently cultivated ornamental alien ("porcelain berry") that was first reported from Ky. by BA in 1992. It has escaped into parks, roadsides and other urban and suburban sites, but it has not yet spread significantly into rural areas. In Louisville, it became locally dominant at Cherokee Park after the 1974 tornado, and it is now widespread across the city (P. Haragan, pers. comm.). It is also becoming locally abundant in Lexington (FAYE), especially along Wolf Run near Clay's Mill Road and Allendale Drive, where large vines have been allowed to develop in wilder streamside vegetation. Plants often branch and flower at only 1-5 m above the ground, enabling the plants to entangle low to tall shrubbery of Rubus spp., Lonicera maackii and others. Flowering shoots are largely glabrous, but non-flowering shoots closer to the ground are sometimes pubescent, then resembling Vitis vulpina. Control is difficult, unless complete removal of vegetation is an option. Small humans could be given botanical training, handsaws and glyphosate bottles, then sent in to do their best. However, cut stumps may be impossible to treat since they push so much sap out (J. Wysor, pers. comm.).
