The inclusion of Thorelia montana Gagnepain as a synonym in FRPS (74: 42. 1985) is incorrect; Camchaya montana (Gagnepain) Kerr is a distinct species restricted to Laos and Vietnam, differing by the almost linear outer phyllaries and smaller florets, ca. 3.5 mm, only 12-30 per capitulum. If it were synonymous then the name C. montana would have priority.
