A new species of Nymphanthus, N. vietnamensis T.A.Le, Tak.Yamam. & Tagane is described from Quang Tri Province and Thua Thien Hue Province (currently Hue City), central Vietnam. It is similar to N. namkadingensis but distinguished by its branchlet with 14–30(–40) leaves (vs. 50–60 in N. namkadingensis), leaf blades with 3–6 pairs of secondary veins (vs. 8–12 pairs), pistillate pedicel of 8–9 mm long (vs. 10–16 mm long), disc of pistillate flowers with 4–6 free rectangular segments (vs. connate and annular), and subglobose capsules (vs. ellipsoid). A detailed description, photographs, and information on the distribution and ecology, vernacular name, phenology, and preliminary conservation status are provided for the species.
