Taxonomic significance of cypsela morphology for the tribe mutisieae (s.l.) (Asteraceae) from Pakistan

摘要

Cypselas of 5 species distributed in 3 genera of the tribe Mutisieae (s.l.) were examined from Pakistan to assess their taxonomic significance. Micromorphological characters of cypsela including shape, pappus and carpopodium have been proved very rewarding to evaluate the taxonomic decisions both at the generic and specific levels.
