FLORAL MICRO-MORPHOLOGICAL CHARACTERS
AND THEIR TAXONOMIC SIGNIFICANCE FOR THE TRIBE SENECIONEAE (ASTERACEAE)
FROM PAKISTAN AND KASHMIR RUBINA ABID*, AFSHEEN ATHER AND M. QAISER
Abstract: 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.
Key words: Asteraceae, Senecioneae, Receptacle, Endothecial tissues.
