A new species of Orinus Hitchcock, O. alticulmus L. B. Cai & Tong Lin Zhang, is described and illustrated. This species is endemic to Qinghai province, China, occurring at altitudes of 2450–2600 m on sandy soils. It resembles O. kokonorica (K. S. Hao) Tzvelev, but differs from that species by its slightly effuse panicles, longer spikelets usually with five or six florets, purple-yellow anthers, shorter caryopses, and the paleas usually longer than the lemmas. A key to the five species of the genus is provided.
