Genetic distance.

<p>Distribution of intra and inter specific K2P mean divergence (arranged in ascending order). (a) ITS2 and ITS2+<i>matK</i> (concatenated) are represented by grey and black colors respectively. (b) For <i>atpF-atpH</i>, <i>psbK-psbI and rpoC1</i> markers maximum intraspecific distance and minimum interspecific distance to nearest neighbor are represented by a bar.
