Pseuderanthemum multiflorum (Acanthaceae), a new species known only from Thailand, is here described and illustrated. It is distinguished from P. graciliflorum by inner corolla tube and pistil being glabrous instead of puberulous and by calyx lobes 4.5–6 mm long instead of 3–4 mm long. Comparison of morphological characteristics are provided.
