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.
