A palynotaxonomic study of Korean Adonis (Ranunculaceae)

Abstract

The pollen morphology of Korean Adonis was examined to clarify its specific recognition. Pollen grains were divided into two major types, according to the size and number of their echinae; those with many small echinae were further subdivided into two subtypes: 2 to 3 aligned foveolae vs. unaligned foveolae. The three types of pollen morphology determined here agree well with recent taxonomic treatments of Korean Adonis. Those analyses, based on morphological and molecular properties, previously recognized Adonis amurensis, Adonis multiflora, and Adonis pseudoamurensis.
