Abstract

The new species Dregea taynguyenensis from Vietnam is described, illustrated and compared with the other Dregea species occurring in Vietnam and neighbouring countries D. cuneifolia, D. sinensis, D. volubilis and D. yunnanensis. Dregea taynguyenensis differs from these species by the leaf blade secondary veins number, calyx lobes shape, and corolla lobes size.
