Morphometric Study of the Genus Indigofera L. in Karnataka
The relationship among thirteen species of Indigofera is described using eight quantitative characters based on both fresh and herbarium specimens. The results of Principal Component Analysis (PCA) and Cluster Analysis divulge that only three characters examined accounted for about 78% importance in the delimitation in the taxa. In this study, the clusters that exist between Indigofera coultea and I. wightii is having the coefficient 12.208, whereas the I. caerulea and I. cordifolia is 102.476 showing great degree of agglomeration. The positive correlation was observed between plant length and number of seeds, Lf length and lf width and inflorescence length and fruit length at 5% level of significance. Also highly positive correlation was observed between fruit length and number of seeds at 1% level of significance. In conclusion, this study has demonstrated the importance of numerical analysis in taxonomic work, with the combination of a number of morphological characters to achieve ample demarcation with better implication for the taxonomy of these species.
