Present paper deals with the cytological evaluation of one species each belonging to 9 different genera of 6 families of Polypetalae from three selected areas such as Kashmir and distantly located Districts Kangra and Sirmaur of another state Himachal Pradesh from Western Himalayas. The chromosome numbers have been recorded for the first time on worldwide basis for the species, <I>Parthenocissus semicordata</I> (n=24) and <I>Silene moorcroftiana</I> (n=24). <I>Filipendula vestita</I> forma <I>vestita</I> with haploid chromosome number, n=7 has also been worked out for the first time. The present chromosome number n=14 for <I>Lathyrus aphaca</I> adds a new tetraploid cytotype to already reported diploid ones. In addition, new aneuploid cytotypes have been worked out for the first time for <I>Desmodium microphyllum</I> (n=10), <I>Impatiens laxiflora</I> (n=8), <I>Ranunculus diffusus</I> (n=14), <I>Thalictrum foetidum</I> (n=8) and <I>Vicia tetrasperma</I> (n=6). The presence of B- chromosomes (0-1B) also makes the first report for the species, <I>Ranunculus diffusus</I>.
