Cypsela morphology and its taxonomic significance within the genus Scorzonera L. (Cichoreae-Asteraceae) from Pakistan and Kashmir
RUBINA ABID
Abstract
Morphological characters of cypsela for 17 species of the genus Scorzonera L. were examined from Pakistan and Kashmir to assess their taxonomic significance. Macro and micro morphological characters of cypsela, pappus and carpopodium were studied by light and scanning electron microscopy. The genus showed great variations however, linear shape of cypsela was found to be dominant and ribbed surface was prevalent within the genus. Pappus were found in one or two series. Carpopodium was basal or sub basal with the variety of shapes. The data obtained was also analyzed numerically and found rewarding to strengthen the taxonomic decisions at specific levels.
