Isodon aurantiacus Y.P. Chen & C.L. Xiang (Lamiaceae), a new species from the Yarlung Zangbo River Valley in Tibet, China, is described and illustrated. It is morphologically close to I. parvifolius and I. tenuifolius, but can be distinguished from the former by the plants being dotted with aurantiaceous glands, corolla tube included in the calyx, and anterior corolla lip much recurved, and from the latter by the plants being densely aurantiaceous-glandular, larger lamina and corolla, and calyx 2-lipped to half its length.
