Morphometric Analysis of Exacum (Gentianaceae) from Kolhapur District

Five Exacum species from Kolhapur District were morphometrically analyzed with the help of PCA, cluster analysis and CD. All these tests revealed that Exacum bicolor Roxb. is morphologically very distinct and Exacum petiolare Griseb. and Exacum pedunculatum L. are closely related with each other. The sequence of the species relationship is as per given succession Exacum pedunculatum L. p Exacum petiolare Griseb. (E. pedunculatum L. var. petiolare Trim.) Exacum pumilum Griseb. p Exacum lawii Cl. p Exacum bicolor Roxb. (E. tetragonum Roxb).
