Crepis desertorum (Asteraceae, Cichorieae), a new species from northern Xinjiang (China) based on morphological and molecular data

Abstract

Abstract: Crepis desertorum from the Junggar Basin of northern Xinjiang, northwestern China, is described as a new species. Molecular studies indicate that the species is closely related to Crepis frigida. Morphological studies indicate that it is similar to Crepis sancta subsp. bifida but differs from the latter taxon in having glandular hairs on the stem, a flat receptacle and dimorphic achenes. Chromosome features and pollen and achene ultrastructure also are described for the new species.

Key words: Karyotype, Micro-morphology, Pericarp, Pollen, Taxonomy
