Abstract


Stipa dickorei sp. nov. from the Western Tibetan Plateau (China) is described. The new species is morphologically similar to S. regeliana, but they differ from each other in the length of ligules of vegetative shoots. Stipa dickorei is also similar to S. aliena, however they differ in the shape of panicle, which is contracted with straight branches in S. dickorei, and lax with flexuous branches in S. aliena. Images of macromorphological and micromorphological structures of the new taxon are provided. Additionally, new records of S. borysthenica, S. richteriana, and S. zalesskii, species not listed in the recent Flora of China, as well as a checklist of Chinese feather grasses are also presented.
