摘要：

Dasypyrum (tribe Triticeae) is revised. Two species are recognized: the annual D. villosum (2n = 14) and the perennial D. breviaristatum (2n = 28). The typification of D. villosum is discussed. The combination D. hordeaceum is demonstrated to be based on a later homonym and for that reason a new combination, D. breviaristatum, is made. A key and a map showing the distribution of the species are presented. Interspecific hybridization and the phylogenetic relationships of the genus are discussed.
