Cytomorphological exploration has been undertaken in 14 species of the Scrophulariaceae from Kashmir, Himalaya. The varied gametophtyic chromosome counts of n=23 for Veronica cana and diploid chromosome number i.e. n=7 for V. persica are reported here for the first time on global basis. Besides this 0 to 2 B-chromosomes have been observed in Verbascum thapsus for the first time. Likewise Digitalis grandiflora (n=28) and Scrophularia scopolii (n=13) are first chromosome reports from India. The meiotic course observed in these scrophs is normal except some irregularities like bridge formation in Mazus japonicus and Pedicularis rhinanthoides, interbivalent connections in P. pectinata and precocious disjunction in Euphrasia officinalis. Morphologically the different accessions within a species showed no conspicuous differences except Digitalis purpurea that has been seen to exist as three morphotypes on flower colour basis.
