What is "bignonia capreolata"

Bignonia \Big*no"ni*a\, prop. n. [Named from the Abb['e] Bignon.]

1. (Bot.) A large genus of American, mostly tropical, climbing shrubs, having compound leaves and showy somewhat tubular flowers. Bignonia capreolata is the cross vine of the Southern United States. The trumpet creeper (also called the trumpet vine), with large red tubular flowers, was formerly considered to be of this genus, but is now classified as Campsis radicans.

2. any member of the family Bignoniaceae, including the bignonia[1], catalpa, trumpet creeper, and princess tree. They typically have brightly colored tubular (trumpet-shaped) flowers.

Bignonia capreolata is a vine commonly referred to as crossvine. The common name refers to the cross-shaped pattern revealed when the stem is cut; this pattern results from four radial wedges of phloem embedded within the stem’s xylem. It is native to the central and southern United States. The vine climbs without twining but does produce tendrils. It produces long tubular flowers which are red and yellow and frequently have a mocha fragrance. The leaves are dark green to almost purple and produced as opposite pairs with terminal tendrils. The vine often climbs very high, with leaves only remaining on the uppermost portion of the plant. Crossvine can spread aggressively through stolons and become invasive unless properly managed.

There was for some time confusion surrounding the name of this plant, which was apparently sometimes referred to as "Bignonia crucigera," a name more properly referring to a different plant altogether.
