A new species of Leymus section Racemosus , L. pluriflorus L.B.Cai & T.L.Zhang, is described and illustrated. It grows in the eastern part of Qinghai Province and the southern part of Gansu Province, China. It most closely resembles L. crassiusculus L.B.Cai, from which it differs in having longer rachis internodes, some pedicellate spikelets, more florets per spikelet, glabrous lemmas, shorter paleas and shorter anthers. It differs from all other Chinese species taxa in Leymus with regard to the large number (8–12) of florets in its spikelets, and from all species of Leymus in adjacent countries in having three to four spikelets per node. © 2009 The Linnean Society of London, Botanical Journal of the Linnean Society , 2009, 159 , 343–348.
