Thirty six taxa of Monocots from W. Himalayan region have been studied. Six species have been investigated for the first time. These are Hypoxis aurea (2n=54), Iris duthieii (2n=22), Dioscorea glabra (n=20), Juncus membranaceus (n=60), Eriocaulon sieboldianum (n=9) and Roscoea procera (n=13). New chromosome numbers have been documented for another ten species, namely, Iris aurea (2n=34), I. nepalensis (2n=28), I. spuria (n=20), Juncus inflexus (n=40), J. lampo-carpus (n=40), Aneilema divergens (n=30), Tinantia fugax (n=33), Roscoea alpina (2n=42), Cautleya spicata (n=13) and Hedychium spicatum (n=26). Base number x=13 has been suggested for the genus Cautleya. B-chromosomes have been encountered in Tradescantia canaliculata. Detailed karyotype analysis has been made in Hymenocallis littoralis (2n=46), Narcissus poeticus (2n=21), N. incomparabilis (2n=21), Zephyranthes carinata (2n=48), Z. candida (2n=38), Hypoxis aurea (2n=54), Iris aurea (2n=34), I. duthieii (2n=22), I. kumaonensis (2n=24) and I. nepalensis (2n=28).
