Abstract

The tribe Vernonieae of the Asteraceae with about 70 genera and 1500 species has two main centres of distribution in tropical America and tropical Africa. It is also fairly well represented in south-east Asia. 37 genera are monotypie. In South India about 50 species belonging to 5 genera have been recorded. This review makes a current assessment of the systematic status of the tribe from various points of view, morphology-anatomy, cytology, chemical constituents, geographical distribution, based on a recent study of the tribe by one of the authors. It has been shown that some of the morphological-anatomical attributes like, trichomes, stomata, pappus, inflorescence, cytological situation as revealed by a karyomorphological analysis, chemical constitutes like flavonoid compounds and geographical distributional features, may all be of value in the assessment of the systematic status of the taxa concerned. Some nomenclatural aspects have also been discussed.
