Discussion

Decumaria barbara is a rare escape from cultivation in New York.

Decumaria sinensis Oliver, of central China, differs from D. barbara in being a low-climbing vine with semipersistent or persistent leaves, stigmas almost completely sessile, and in plants growing at elevations of 600–1300 meters.
