  1. On the basis of examination of more than 2000 specimens ( including types ) from 15 herbaria worldwide, the characters features of species, phonological phase, ecoloigical habit and the relation to close species were analyzed, recorded and described, the disputed species were compared, measured and counted in detail, the quantitative analysis to different characters was done through dot - map, the variation pattern of major morphology characters was analyzed and their significance for a better delimitation of the species was evaluated
