MICROMORPHOLOGY OF CYPSELA AND ITS TAXONOMIC SIGNIFICANCE OF SOME GENERA IN THE TRIBE INULEAE (ASTERACEAE) FROM PAKISTAN
RUBINA ABID AND NOUREEN ZEHRA
Abstract
Cypsela morphology of 10 taxa belonging to the tribe Inuleae of the family Asteraceae was examined using light and scanning electron microscopy. The taxa included representatives of the genera Pegolettia Cass., Varthemia DC., Asteriscus Torn.ex Mill., Carpesium L., and Blumea DC. Cypsela micromorphological characters are found taxonomically significant both at generic and specific levels.
