We describe and illustrate Aristolochia neinhuisii (Aristolochiaceae), a new species in subgenus Siphisia from the Highlands of Vietnam. It resembles A. hainanensis, A. tonkinensis and A. howii, but differs from them by having some of the leaves organized opposite-like, instead of exclusively alternate, with a 2-lobed apex and a slightly cordate base, a horseshoe-shaped perianth with chestnut upper tube, and a yellow flower throat without dots.
