Floral micro-morphological characters and their taxonomic significance for the tribe senecioneae (Asteraceae) from Pakistan and Kashmir

The micro-morphological characters viz.,receptacular surface and endothecial tissues of 26 species distributed in 9 genera of the tribe senecioneae were examined using light and scanning electron microscopy (sem). the endothecial tissues found to be significant for the generic delimitation within the tribe senecioneae. however,a variety of receptacle surfaces i.e.,alveolate,areolate,fimbrillate,foveolate and scorbiculate was observed and to some extent they may be used for specific delimitation. © 2014,pakistan botanical society. all rights reserved.
