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.
