Two new species, Caulokaempferia kayinensis Picheans. & Sangnark and C. monensis Picheans. & Sangnark (Zingiberaceae), are described. This is the first report of the genus from Myanmar. The sessile inflorescence of C. kayinensis, hidden in the uppermost two leaf sheaths, is unique among the yellow-flowered group of the genus. The long ligule, ovate bract, and the bract-formation on inflorescence are characteristic of C. monensis. Full descriptions, together with ink line-drawings with water-color and photographic illustrations, of these new taxa are given.
