Abstract
The family Apiaceae comprises 428 genera worldwide, of which 68 are represented in India. Karnataka P.K. Mukh. & Constance, Pinda P.K. Mukh. & Constance, Polyzygus Dalzell, Sivadasania N. Mohanan & Pimenov and Vanasushava P.K. Mukh. & Constance are endemic genera to the country. The present communication is an attempt to provide chromosome counts and basic karyomorphology of Karnataka, Pinda, Polyzygus and Vanasushava. Somatic chromosome counts 2n = 22 and meiotic chromosome counts n = 11 are reported for the first time in Karnataka and Pinda while in Polyzygus 2n = 36 and in Vanasushava 2n = 44 are reported as new cytotypes in present investigation. Karyomophologically Pinda and Vanasushava showed affinities with Heracleum L. while Polyzygus showed advanced karyotype symmetry.
