Abstract
Five W. Himalayan species of the genus Allium have been studied. Two species, A. blandum (2n=32) and A. consanguineum (2n=16) have been investigated for the first time. A. stracheyi was found to possess 2n=16. In the somatic complement of A. victorialis the individual chromosomes of most of the pairs were found to be unequal varying greatly in length and arm ratio which is suggestive either of unequal translocations or hybrid nature of the taxon. The presence of only one pair of subterminal chromosomes in the complement of the tetraploid species A. blandum suggests its origin either from different parental sources or chromosomal repatterning which seems more probable.
