Liaoning, Nei Mongol, Xinjiang [Afghanistan, India, Kashmir, Kazakhstan, Kyrgyzstan, Mongolia, Pakistan, Russia, Tajikistan, Turkmenistan, Uzbekistan; N Africa, SW Asia, Europe; introduced in North America].This species was recorded in FRPS from Xizang, but the present authors have seen no material from that autonomous region.Neslia paniculata is represented in China by subsp. paniculata, which has a subtruncate fruit apex, whereas subsp. thracica (Velenovsky) Bornmüller (from C and SW Asia and S Europe) has a distinctly umbonate fruit apex.【引自：Flora of China】
